Best of times, worst of times

his winter has been brutal for northern and northeastern states, with record snowfall and record temperatures, and with abnormal icy conditions even in southern states such as Georgia.

In addition to the havoc wreaked by brutal blasts of arctic cold and relentless buildup of the white stuff, streets and highways are peppered with destructive potholes. The bad news for vehicle owners was delivered in terms of torn tires, bent rims, weak batteries, frozen fuel lines, snow-packed air ducts, etc., in addition to countless incidents of collision damage.

Amidst the severe temperature shifts, any windshield that had a previous chip likely snapped and cracked due to the combination of below-freezing temperature and mechanical stress. The combined heavy snowfalls, frigid temperatures alternating with brief warm-ups followed by sub-zero weather created hard-packed lumps of ice in driveways, parking lots and side streets.

Drivers who attempted to mush through such obstacles often found themselves impaled and stuck, requiring a push or a tow to release their vehicle from the grips of the ice monster. The results in many cases: dented or torn oil pans, damaged brake or fuel lines, torn CV shaft boots, overheated transmissions and in some cases even bent subframes and damaged suspension arms.

While these horror stories presented nightmares for drivers, the recent weather has created a boon for repair shops. Though

we certainly don’t want to proft from the misfortunes of others, the recent weather attacks have generated substantial increases in repair work, which is good news for shops.

While this might present opportunities for unscrupulous shops to take advantage

of such a windfall of work by charging a premium to handle emergency repairs, this winter season has served as a showcase for the integrity and empathy that reputable shops have displayed, especially for customers whose budgets have been stretched beyond the breaking point.

I know of many instances where shops have saved the day for stranded drivers by working late hours and providing price breaks for those in need. We should take pride in the fact that our industry is comprised of many good-hearted folks who go above and beyond when circumstances demand. Instead of profteering and bleeding people dry, they step up to the plate and act as human beings should. â—?

Tech tips From module-to-module communication to wireless ignitions and leaking rear main seals DIAGNOSTIC MULTIPLES From an engineering standpoint, most technicians can see the logic behind moduleto-module communication. In theory, it makes sense to have a single input such as a vehicle speed sensor feed just one module, and then have that module share the information over a pair of data bus wires to other modules. Unfortunately for the technicians faced with the challenge of diagnosing and repairing these problems, module-to-module communication often makes our job signifcantly more diffcult. Not only does it increase the requirement of diagnostic equipment, since many of these problems can only be diagnosed with factory scanners, but it requires today’s technicians to be computer network diagnosticians as well. Of course with increased module-to-module communication comes increased unique and multiple simultaneous problems, and any one module shutting down can affect everything — from interior lights malfunctioning to the vehicle not starting.

Recently I took in a 2007 Ford Crown Vic-

the ABS module, we found there was no communication to the scanner. The frst plan of action was to check the powers and grounds to the ABS module; the ignition power feed to the module was not showing battery voltage as it should. The fuse was checked and found to be OK. Further tracing of the circuit found a broken wire in the harness.

Once the wire was repaired, communication was restored to the ABS module, the ABS light went out, and the power steering returned.

When dealing with a multiplexed vehicle with multiple problems that began at the same time, the best plan is to pick one problem and concentrate on resolving it. If too many problems are tackled at once, it’s very easy to lose direction and start going in circles on a diagnosis. One useful test, if available, is to perform a “‘network” or automated test, where the scan tool attempts to communicate with all the modules on the vehicle’s networks. If a particular module is not communicating, addressing that concern is normally a good place to start.

WIRELESS IGNITION

Ford’s 2007 Crown Victoria utilizes a variable assist power steering system.

toria. The complaint was that the ABS light was on and the power steering was lacking assist. This vehicle model uses a variable assist power steering system that defaults to minimal assist in the event of a system failure. While trying to retrieve codes from

Chrysler’s newer vehicles have gone wireless. One of the new systems is the Wireless Ignition Node (WIN). This system uses a transponder remote keyless entry fob integrated key (FOBIK) which replaces the traditional metal key.

With all of the functions of a traditional remote keyless entry fob, this unit also has a metal key blade for valet functions to lock the glove box and to open the door in the event of a dead battery, a remote keyless entry failure or a bus failure. This unit serves as the remote keyless entry fob and the electronic ignition key.

The functions of the WIN are: •

Sentry key immobilizer (SKIM)

10 | March/April 2014

• • • • • • •

Wireless receiver for remote keyless entry Brake transmission interlock (BTSI) Clock master Steering column lock interface (BUX) for export only Tire pressure monitor (TPM) system Remote starting Electronic ignition switch

When entering the vehicle, the FOBIK is used to open the door locks and disarm the alarm system via the remote keyless entry.

The FOBIK is then inserted into the WIN, much like an ignition key. But the similarity ends there. When the FOBIK is near the WIN, it transmits a secret key code via radio frequency to the WIN which in turn passes this information on to the controller area network (CAN). The WIN is hard wired to the CAN C bus. The signal is then sent to the powertrain control module (PCM). At this point, if it is a valid key, the immobilizer is satisfed and the vehicle is ready to start. The signal is then passed through the central gateway on the vehicle, usually the Totally Integrated Power Module (TIPM).

This information is then gathered by the other controllers via the CAN B, the CAN Interior High Speed (IHS) or in some cases the Locale Interface Network (LIN) bus. Once the FOBIK is turned to the “start” position in the WIN, the Win again transmits a message on the CAN bus for starter engagement and when it returns to the run position, the “ignition on” functions through the PCM and the central gateway to the other modules.

The WIN then monitors the tire pressures over the bus and provides the BTSI function via a hard wired input from the shifter assembly and brake switch.

The system became available on some 2007 vehicles and was standard on all Chrysler, Dodge and Jeep vehicles by 2009.

LEAKY REAR MAIN ON LS A local customer makes his living by “rebuilding” late model salvage cars and reselling them. He tends to perform his own work, and he’s not exactly an expert technician, so he routinely asks us to fgure out

any problems that he can’t solve on his own.

After “restoring” a food car that he bought at auction, he “rebuilt” the engine and told us that the rear main is leaking and he can’t fgure out why.

The engine at hand was a GM LS1. This engine’s crankshaft features a one-piece rear main seal that’s held in at the engine’s rear cover. He had been installing the new seal to the rear cover, oiling the seal lips, and then pushing the rear cover onto the rear of the crank. When doing this, the seal’s two inner lips would fold back, allowing oil to simply walk past the seal.

The LS rear main seal installs to the rear engine cover. Do not lube the seal lips prior to installing the cover to the engine block.

The proper method is to install the seal dry (this may go against the thinking of many, but it’s important). Also, a new seal will include a white nylon seal guide (which this guy had been ignoring and throwing away).

The guide needs to be installed to the inside of the seal and held in place while pushing the rear cover onto the crank. The guide prevents the lips from folding back. Once the seal is captured onto the crank rear fange, the guide simply pops out.

Any time you install a rear main seal onto any LS crankshaft, you must use this nylon guide. It serves as a temporary installation tool. ● (All tech tips are courtesy of Identifx Inc. For more information, see www.identifx.com.)

Tire pressure monitoring systems

By Mike Mavrigian

W

e’ve discussed the subject of TPMS (tire pressure monitoring systems) in the past, but this is a topic that can always beneft from an update. Considering the proliferation of TPMS in today’s market, it’s vital that we gain as much understanding of these systems as possible.

location is under-infated; or the warning system may indicate which location (LF, RF, LR, RR) is under-infated.

INDIRECT TPMS

Instead of monitoring actual infation pressure, an indirect system relies on the vehicle’s ABS to monitor tire rotational speed (since a lower-pressure tire will rotate at a different speed due to the decrease in overall tire diameter). When the ABS detects a different rotational speed, it alerts the driver. This works as designed as long as the system detects a difference in rotational speed as compared to the remaining tires.

However, if all four tires are under-infated by the same amount, the system may not detect a difference, and no alert warning Typical components of a “clamp-on” style may be provided. A direct TPMS is much sensor. The sealing washer seats against the inside surface of the wheel’s valve hole. more accurate by comparison.

The CONDITIONS WHEREIN THE use of a steel or brass cap can also lead to SYSTEM MAY NOT FUNCTION radio wave signal interference.

RELEARN VS. PROGRAMMING Vehicle relearn and sensor programming are completely different procedures.

Confusion is common due to the availability of aftermarket TPMS sensors that are offered as “programmable,” “universal” or “cloneable” sensor units. These sensors must be programmed with the proper protocol/application information for the vehicle before they can be installed on the wheel. An exception is VDO’s Redi-Sensor which does not require programming prior to installation (these sensors are already loaded with the programming needed to function with the vehicle’s system).

Regardless of the brand of sensor, once programmed and installed, the sensors must then be relearned to the vehicle, even if only one sensor has been replaced. It’s not uncommon for shops to overlook the necessary relearn step, proceeding under the assumption that the sensor programming was all that was required. This misunderstanding can result in comebacks and customer complaints.

Vehicle relearn is a standard and mandatory procedure whenever a sensor has

PROPERLY

1. Similar radio frequencies in the immediate area may interfere with the system.

2. A radio device of similar frequency is being used in the vehicle.

3. Excessive snow/ice on the vehicle (especially around wheels and wheel wells) may cause poor transmitter radio signal operation.

4. The tire pressure warning valve subassembly’s sensor battery may be depleted.

5. Wheels may be installed on the vehicle which do not feature a tire pressure monitor valve sub-assembly.

6. Use of studded snow tires or tire chains may disrupt radio signals.

7. If non-specifed wheels are used, the system may not function properly because the radio waves are transmitted at different angles from the pressure sensor.

8. Depending on the type of tire used, the system may not function properly even if the correct specifed wheels are used.

NOTE: The average life of the grommet of the tire pressure monitor valve sub-assembly is about fve years, at which time the grommet should be replaced.

TIRE MOUNTING

2. Press and release the brake pedal once.

3. Cycle the ignition button from OFF to RUN three times, ending in the RUN position (this is the same procedure that would be used if the vehicle is key-ignition equipped).

4. Press and release the brake pedal again, and press the ignition button to the OFF position.

5. Cycle the ignition button from OFF to RUN three times, again ending in the RUN position. When the vehicle horn honks, this indicates that the relearn procedure has been initiated. You are now ready to begin the relearning procedure.

6. Using a TPMS scan tool, trigger each sensor, starting with the LF wheel and working clockwise (LF, RF, RR, LR). If the vehicle is equipped with a spare tire, be sure to trigger that wheel’s sensor as well (after triggering the LR). The TPMS scan tool is held at the tire valve/sensor during triggering.

7. Once the relearn process is complete, the vehicle horn will honk to confrm.

NOTE: The tire should be completely removed from the wheel before installing any new sensor. When dealing with a sensor that is secured to the wheel with a mounting nut, BE SURE to tighten at the specifed torque value. Over-tightening can easily damage the stem.

When mounting the tire onto the wheel, install the inner tire bead frst. Position the main body of the valve sensor approximately in the 7 o’clock position relative to the mounting machine’s bead pusher arm. If the valve sensor is positioned outside this area, it may create interference with the tire bead with resulting sensor damage.

Install the upper bead, being careful not to damage the valve sensor (make sure that the valve sensor is not clamped by the bead).

After the tire beads have been seated and the tire has been fully infated, recheck the valve nut and retighten to the vehicle manufacturer’s specifcation (this will likely be in the 35 in.-lbs. range. Valve stem damage can easily result from overtightening, so ALWAYS refer to the torque specifcations! Check for air leaks with a soapy water solution.

GM VEHICLES EQUIPPED WITH DRIVER INFORMATION CENTER

TPMS SENSOR RELEARN EXAMPLES

This includes Camaros and other models that feature an information display on the dash.

Following are a few examples of the steps required for TPMS relearn. If the replacement sensor(s) require programming, sensor programming must be performed prior to the relearn procedure. The following examples were provided courtesy of VDO for their Redi-Sensor.

FORD WITH PUSH-BUTTON IGNITION Ford vehicles that are equipped with a push-button ignition switch require a specifc sensor relearn procedure. Once the replacement sensor(s) has been installed and all four wheels/tires are mounted to the vehicle, infate all tires to the recommended pressure and follow these steps: 1. Ignition OFF.

1. Place the ignition in the ACC or ON position (do not start the engine).

2. Use the turn signal arm to display the infation pressures of all four tires.

3. Hit SET on the wiper arm to reset the TPMS. 4. A screen pops up displaying “Are you sure you want to relearn?” At this point, push the wiper arm inward to toggle to “YES.” At this time, the vehicle horn will honk twice to alert you to begin sensor triggering.

5. Using your TPMS scan tool, begin triggering the sensors, starting at the LF and working clockwise (LF, RF, RR, LR). Don’t forget to trigger the sensor in the spare tire if so equipped. You’ll hear a single horn honk as each sensor is successfully

18 | March/April 2014

triggered. You’ll hear a double-honk when the relearn procedure is fnished.

CHRYSLER, MAZDA AND SOME EUROPEAN VEHICLES This procedure applies to TPM systems that are otherwise auto-relearned once the vehicle is driven. If driving the vehicle is impractical at the time, a TPMS scan tool may be used to perform the relearn in the shop.

1. With wheels/tires installed to the vehicle and infation pressure adjusted to specifcation, trigger all sensors using an OBD II-compatible TPMS scan tool, starting with the LF and working clockwise (LF, RF, RR, LR). Trigger the spare (if so equipped) last.

2. Once all sensors have been triggered, place the ignition switch to the ACC or ON position (do not start the engine).

3. Connect the TPMS scan tool to the vehicle’s OBD II port in order to upload the sensor ID. The TPMS scan tool displays a confrmation once the process is complete, which may take several minutes. If your scan tool is not capable of performing this process, the vehicle must be driven in order to complete the relearn.

GM KEY FOB RELEARN NOTE: Not all GM vehicles are enabled from the factory with the key fob vehicle relearn initiation method. (For reference, see www.autoserviceprofessional.com for the chart on applicable vehicles that can use the key fob relearn method.)

1. Ignition ACC or ON (do not start the engine).

2. Press and hold the unlock and lock buttons on the key fob at the same time.

When you hear two horn honks, this indicates that the vehicle has entered the relearn mode.

3. Using your TPMS scan tool, trigger each wheel sensor, starting with the LF and working clockwise (LF, RF, RR, LR). The turn signal lamps will illuminate as you go. As each sensor is triggered and the sensor ID is captured, you should hear a

single horn honk. Remember to trigger the spare.

4. When relearn is complete, you’ll hear two horn honks. A “Relearn successful” message may also be displayed on the driver information center.

Before installing a sensor, make sure that the wheel well is cleaned of dirt, debris or oils.

UNIVERSAL SENSORS The OEs, in their usual fashion, have created an incredibly vast proliferation of pressure sensors (there are no industry standards, so everybody apparently felt the need to devise their own proprietary sensors in terms of data transmission protocol, with an estimated 75 versions currently in OE use). As a result, it’s impossible (or least extremely impractical) for any shop to stock enough sensors to accommodate all makes/ models/years (you’d go broke just trying to stock these things in an attempt to achieve full coverage).

The solution: universal tire pressure monitoring sensors. These universal sensors allow you to basically grab a new “blank” sensor and program it for the application.

Currently there are three sources for universal sensors: Continental’s Redi-Sensor, Schrader’s E-Z Sensor and Myer Tire Supplies’ Sens-It. While none of these universal sensors will accommodate 100% coverage, we’re told that they will cover roughly 85% to 90% of the current market. The makers are continually trying to obtain protocol information from the automakers, so if certain application information hasn’t yet been made available to the aftermarket, it’s a waiting game for the sensor makers.

CONTINENTAL VDO REDI-SENSOR This sensor is akin to a universal TV remote control unit, in that it’s designed to cover all (available) protocols in a “shotgun” approach. The sensor is already pre-programmed with all system protocols. It sends out all frequency protocols (multiple data commands in a continuous wave), allowing the vehicle’s ECU to grab the one that fts. These sensors are preprogrammed, and are not programmable (similar to a read-only CD that can’t be over-written). Basically, install and go.

R/R/R roundup R134a recover/recycle/recharge equipment

By Bob Weber

T

he world of automotive service continues to change at an accelerated rate.

That includes mobile air conditioning service challenges for service technicians.

Currently, techs and shop owners must deal with electrically driven compressors found in hybrid and plug-in electric vehicles. That means recover/recycle/recharge (R/R/R) equipment must be up-to-date beyond compliance with Environmental Protection Agency (EPA) rules and the Society of Automotive Engineers standard J2788.

Briefy, the purpose of the standard, which was revised in January 2013, as stated by SAE, “... is to establish the specifc minimum equipment performance requirements for recovery and recycling of HFC-134a that has been directly removed from, and is intended for reuse in, mobile air-conditioning (A/C) systems. It also is intended to establish requirements for equipment used to recharge HFC-134a to an accuracy level that meets Section 9 of this document and SAE J2099.

The requirements apply to the following types of service equipment and their specifc applications. a. Recovery/Recycling Equipment, b. Recovery/Recycling-Refrigerant Charging, c. Refrigerant Recharging Equipment Only.”

If you service hybrid or plug-in electric vehicles, make sure the equipment you use is certifed for these high-voltage systems.

If you are looking for the latest R/R/R service equipment, we want to help. Following is a roundup of equipment to better help you make an informed decision. Here is the latest on SAE J2788-compliant equipment.

Robinair Cool-Tech 34988 The Cool-Tech 34988 from Bosch Automotive Service Solutions LLC’s Robinair

division combines simple operation with superior accuracy. It recovers, recycles, evacuates, leak tests, and recharges R134a quickly and accurately. A fully automatic function allows the technician to recover, vacuum and leak test, charge, and then walk away. Other features and functions include automatic refrigerant refll, automatic air purge and oil drain, refrigerant charging and refrigerant management According to the company, the model

Robinair’s Cool-Tech 34988 is highly effcient.

34788 is a UL-listed, single-pass system that meets SAE specifcations for recycled refrigerant. Follow the SAE-J2211 recommended service procedure for the containment of R134a.

The unit includes a 1.5 cfm vacuum pump for fast, thorough evacuation. The compressor pulls the A/C system to 0 psig, then

26 | March/April 2014

works in series with the vacuum pump to achieve highly effcient recovery and immediate recharge. The company says it recovers 20% more refrigerant than other models, and has a charge accuracy of +/–0.5 ounce. There are two large tool storage areas and storage for an extra flter and compressor oils. The control panel fips down when not in use.

Features include full automation to recovery, vacuum, leak test and charge without operating any panel valves; automatic UV dye inject into a vehicle’s system; and automatic oil measure and inject that determines how much lubrication oil is needed based on how much oil was taken out during recovery. It fushes a vehicle’s A/C system with refrigerant, eliminating a residual oil or other liquid. (Flushing adapters sold separately.) The save and print feature lets the user store before-and-after service information and print it for the customer.

There is an indicator light and notifcation alarm when service is complete, or if a problem has occurred. Oil injection has less than 1% cross-contamination, and a vacuum leak test informs the tech of a possible leak. Automatic air purge eliminates damaging air without monitoring gauges or opening valves. An automatic refrigerant refll maintains a user-selectable amount of refrigerant in an internal tank and signals when it is time to change supply tank.

For more information, go to the company’s website at www.robinair.com.

High voltage oil fush

Many automotive air conditioning systems contain PAG (polyalkylene glycol) oil, but high-voltage hybrid systems require POE (polyol ester) oil. Although it acts as a lubricant, more importantly, POE oil isolates the high voltage from the automobile’s chassis.

When doing an oil fush on one of these systems, it is important to make sure there is no residual PAG oil in the service hoses and couplers.

System damage or technician electrocution are possible.

Tip Number One: Give up on current ramping, or don’t even start if you have heard about it.

Back in the day, when 90% of vehicles were made by three American companies, there was not a lot of diversity in what fuel pumps these vehicles had. Not coincidentally, when the amperage of these pumps was ascertained using an amp clamp and a labscope, they produced neat looking waveforms, such as the one seen in Figure 1.

T

he present-day is an interesting time for the automotive technician.

Perhaps now more than ever, the vehicles that are on the road resist breakdown, and with the help of a few repairs can routinely last about 200,000 miles.

This is a far cry from the day when vehicles had carburetors or early versions of fuel injection. While it appears that fuel-saving technologies such as direct fuel injection and the increased use of turbocharg- Figure 1: This 1987 Pontiac Grand Am creates a nice and neat amperage waveform when running the fuel pump. ers may also break down quicker in the future, many of these vehicles are so new they have not Many technicians think that all fuel yet reached the point where they have pumps can be diagnosed this way. However, breakdown-related issues. if they actually tried the technique on vehiSo, the question service technicians need cles made after the year 2000, they would to ask themselves is whether or not they see that the fuel pump waveforms don’t are prepared to deal with a fuel-related no- lend themselves to such easy interpretation. start or misfre.

This fuel pump is fne one of these issues. and this is not even a new vehicle, it is a

1998 model year GM. Further, as one can see in Figure 4, the vehicle’s fuel trim is not highly positive, compensating for a bad fuel pump. It is well within normal range. Quite frankly, the fuel pump is fne.

Further, to effectively current ramp fuel pumps the technician is required to undergo the impossible task of taking specs of every new car he fnds. And it is not always easy to access fuel pump relays.

Rents and taxes are too high and labor is too expensive to waste time doing this, especially when, quite frankly, it does not work anyway.

Tip Number Two: Checking fuel volume is the only way to test for a bad fuel pump or restricted fuel flter.

Many technicians have a fuel pressure gauge and the vehicle usually has a fuel pressure sensor on the rail. Both the gauge and the scan tool can help us test for fuelpump drain back and an underperforming pump, so they can be quite useful.

However, it should be known that just because a vehicle has low fuel pressure, it does not mean that the fuel pump is bad.

For example, a vehicle with a bad fuel flter may have barely any fuel pressure, especially if it is causing such a restriction that the vehicle will not start. Yet, the fuel pump can still be good.

Figure 4: Shown here is fuel trim on the same 1998 Chevy Malibu at +3%. Essentially, anything below 8% to 10%, positive or negative, indicates a normal running vehicle and does not warrant further investigation regarding there being a fuel metering-related issue.

Figure 5: Before replacing the fuel flter on this 2004 Ford Taurus 3.0L, the observed fuel pressure on the vehicle was acceptable.

However, the engine did not have enough fuel volume to start, let alone run.

So, if the shop can spring for the bucks, a fuel volume gauge is the way to go. It is simply placed in line, preferably before the fuel flter, and it tells us both fuel pressure and fuel volume in gallons-per-minute.

Better yet, there is no need to memorize fancy specifcations. Every single vehicle that’s a four cylinder will fow at least 0.4 gallons per minute (gpm) and any other vehicle with a turbo or larger engine will fow at least 0.5 gpm. To be honest, do not be surprised to see even a known-good Honda four cylinder fowing at least 0.6 gpm. If a fuel pump is good, it will generally fow even above these numbers, but when it is bad it will fow below these numbers.

Just remember, if you fow after the fuel Circle 117 on Reader Service Card

40 | March/April 2014

Circle 118 on Reader Service Card

flter (even though most flters are in the tank anyway these days), a bad fuel flter can cut both your pressure and volume.

How can you measure fuel volume without the gauge? If you can command on the fuel pump by jumping the connectors where the relay goes and disconnect the fuel line, you can take an empty windshield washer fuid bottle and see how much fuel you get in a minute. If about half of that bottle gets flled up, your fuel pump is fne.

Figure 6: Even BMW endorses this technique, as can be seen in the repair information available to us from Mitchell 1’s ProDemand software. The Germans give us the specifcation “one liter every 30 seconds” in order to confuse technicians across the ocean. Being that a gallon is 3.89 liters, the technician can surmise that every minute there is about half a gallon of fuel fow on a known-good BMW.

However, sometimes this is too messy and inaccurate. There is one other way to get the job done without purchasing a fuel volume gauge.

If you are performing fuel system cleanings in your shop, chances are you have a tool that connects to the fuel rail in order to fush the injectors out with a cleaning solvent. If this is the case, you can test fuel volume indirectly.

Circle 119 on Reader Service Card

42 | March/April 2014

Circle 120 on Reader Service Card

Figure 7: This is an example of how to hook up even a new vehicle for indirect fuel volume testing. Pictured here is a 2009 VW Jetta 2.0 Wolfsburg Edition.

Simply connect the tool to the fuel rail and fll it up with gasoline instead of solvent. Then, put the tool at about 40 psi

(which may be risky so be sure to wear glasses or a face shield) and start up the engine. If the engine runs normally, then what you have essentially done is proved that there was a fuel volume issue.

Why? Because if the vehicle runs normally hooked up in this fashion when it did not before, the only thing that changed was the volume of fuel that reached the fuel rail.

So, the problem has to be something fuel volume related farther down the fuel system, likely the pump or flter.

Tip Number Three: Be on the lookout for obvious stuff.

Here, on this 1998 Honda Civic, the customer had a bad fuel tank (see Figure 8).

He put a junkyard fuel tank on and, not surprisingly, a few months later, the engine starts running funny.

The M7 1/2-inch-drive air wrench from King Tony of America features a head that’s a mere 4-3/8 inches long. The comfy cushioned grip provides a nice tactile feel, and the grip length and angle provides an ideal balance point. The gun doesn’t feel top heavy at all.

hat appealed to me about the M7 (Mighty-Seven) 1/2-inch-drive air wrench from King Tony of America is its ultra-stubby size. It’s the cutest, shortest 1/2-inch-drive air wrench that I’ve had the pleasure to try.

The M7 offers a beefy, solid feel and is well built. I put this pro-level gun through

its paces over a week’s worth of repair and restoration work, and I’m impressed. While the size and balanced feel is what frst drew me to this gun, I did my best to beat it up and it never whimpered. It feels like a tool that will last.

I measured the wrench at 3-5/8 inches in length, from the back plate to the front nose housing. Overall length from the rear plate to the tip of the anvil measured at

4-3/8 inches. Overall height (not including the air nipple) measured 7 inches. Thickness at the front of the housing measured 2.360 inches, tapering at a rear thickness of 2.185 inches. As far as I know, this has to be the shortest 1/2-inch-drive pneumatic wrench on the market, obviously designed to accommodate tight spaces. The tactile rubber-coated grip area features fnger grooves, with the fnger height area of about 2.760 inches, which provides an ideal fnger grip area for an average-size hand (full grip space with no pinky fnger overhang).

If I were forced to come up with a complaint (considering how much I like this little bugger, pointing out anything negative was diffcult), it would involve the trigger. While the plastic material seems tough enough for heavy-duty use, the very top of the trigger is open/hollow. In an ultra dirty environment I can see the Circle 125 on Reader Service Card

possibility for debris to enter and possibly restrict movement. However, I’m not overly concerned, since the top of the trigger is shielded by the head. As long as you don’t immerse the gun into a bucket of sand, I don’t see this as something to worry about.

The M7 quickly earned a special place in my heart. For me, it’s one of those “must have” tools for dealing with cramped work areas. While I have 3/8-inch-drive guns of similar size, having something this tiny with a 1/2-inch-drive capability and plenty of gutsy reverse torque is a real blessing.

Every time I picked it up, I couldn’t help smiling. It’s just so darned cool.

Cadillac COOLANT TANK LEAK Some 2012 Cadillac Escalade, Chevy Avalanche/Silverado/Suburban/Tahoe, GMC Sierra/Yukon/Denali vehicles may experience a coolant leak. The cause may be traced to an ill-ftting coolant overfow tank nipple.

The leak is caused by excess plastic at the parting seam on the tank nipple, preventing proper hose sealing.

The repair involves sanding the plastic seam on the nipple to create a more uniform sealing surface for the hose. Do not replace

the overfow tank, since sanding the seam will fx the problem; and the replacement tank might have the same excess plastic on the nipple.
