cleans up to 24,000 liters of air per hour when driving 60kmh. An air filter eventually becomes clogged with trapped particles. A clogged filter starves your engine for air, permits unburned rich fuel to enter into the engine which ends up in the oil sump, reducing engine oil lubrication quality, causing excessive engine wear, sluggish performance and poor fuel economy. An air filter is located in the induction passage inside the black box (fuel injected system) and its job is to feed cleaned air via the throttle body to the combustion chamber for proper ignition. It is very easy to check. Just turn on your high beams and a place filter in front of them to see if light is passing through it. If you can’t see the light that means it’s time to replace the filter. It should be inspected at every oil change and replaced every 18 months or 36,000 km, depending on road, weather and driving conditions. A new filter can provide 4 - 5 per cent better gas mileage and engine performance.

Fuel Filters:

Fuel is an engine’s food and its purity is v e r y important, just as pure food is for your health. This is fulfilled by the fuel system which mixes air and fuel in proper ratio and injects it into the engine through inlet ports for a complete combustion with the help of injectors and spark plugs. Fuel filters help ensure the delivery of clean fuel from the gas tank to the engine by stopping contaminants such as rust, water, corrosion and dirt from entering the carburetor (old model cars), throttle body, injectors, fuel pump, and parts that could be damaged by foreign matters. Impurities in the gas tank can also cause the filter to clog and restrict fuel flow, leading to problems such as hard starting, stalling or even injector failure and poor engine performance. A fuel filter is normally located inside or over the fuel tank pickup tube. It is recommended that you buy brand

name gas with the proper grade (see your owner’s manual for details on fuel grade and replacement intervals). Generally, it’s suggested that you replace the in-line fuel filter every 2 years or 48,000 km to avoid unexpected engine problems.

Transmission oil is also a life blood for your car, serving m u l t i p l e purposes. It lubricates internal parts and also transmits power by hydraulic shifting. Bits of metal, friction material, water condensation, dust and other substances can circulate through the hydraulic system. The filter can be contaminated with harmful foreign matter after prolonged operation, causing premature wear or major transmission breakdown. This filter is located inside the transmission oil pan. Some selected manufacturers have a magnetic drain plug which attracts all metals fine particles and holds them until service time. However, it is generally recommended that you service your transmission with oil and filter replacement (if equipped) every tow years or 48,000 km. Some vehicle manufacturers suggest only to drain, fill and flush, as required. See your maintenance schedule for details.

Many vehicle owners don’t even realize that they have a cabin air filter, much less if it ever needs to be replaced. However, your cabin air filter provides a very important service to the driver and passengers in this age of increasing global pollution. Have you ever driven behind a smoky car and experienced the change in cabin air quality and smell? Then you need to replace your cabin filter!

Your car’s ventilation system is a breeding ground for a wide variety of microbes, including mould, bacteria and germs. When you turn your ventilation fan on, these microorganisms are blown into the passenger compartment and inhaled by you and your family. This poses a potentially harmful health problem, especially for people with respiratory sensitivities and for children. Hence a cabin air filter is an integral part of your vehicle’s ventilation system that removes pollutants from the air before they get inside your vehicle. They can also clog a vehicle’s heating and A/C cooling system, reducing performance. Periodic replacement of a cabin air filter is a quick and inexpensive way to protect the inside air of vehicle from unwanted airborne particles. Cabin air filters are typically located under a vehicle’s dashboard or attached to the glove box. Others may be located in the engine compartment. You should replace your cabin air filter as soon as possible if interior air smells musty or moldy. Your cabin air filter should be inspected on every oil change and replaced once a year or every 24,000km or earlier, depending on road and environmental conditions.

Turn your fan ON at high speed, drawing outside air in (not in recirculation mode). Aim all directionals to the centre of the vehicle. Turn on your A/C control and ensure that all of your windows are closed. Now take an aerosol household germ killer and spray it on the outside air vents below the front windshield. This will draw the germ killer through the filter and clear and kill all germs that cause odor in the cabin through the ventilation system. You can also choose an air freshener instead of a disinfectant spray to bring fragranced air into your car’s cabin. This simple task will improve in-car air quality for you and your whole family. Regular automotive filter maintenance spares you the expense of avoidable and unexpected major repairs, saves you money and adds more trouble-free years to your vehicle. The Driver Magazine
