BLEEDING 1. 2.

CHECK FLUID LEVEL (See page SR-5 ) JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH STANDS 3. TURN STEERING WHEEL With the engine stopped, turn the wheel slowly from lock to lock several times. 4. LOWER VEHICLE 5. START ENGINE Run the engine at idle for a few minutes. 6. TURN STEERING WHEEL (a) With the engine idling, turn the wheel to left or right full lock position and keep it there for 2-3 seconds, then turn the wheel to the opposite full lock position and keep it there for 2-3 seconds. (b) Repeat (a) several times. 7. STOP ENGINE

Normal

8. CHECK FOR FOAMING OR EMULSIFICATION If the system has to be bled twice specifically because of foaming or emulsification, check for fluid leaks in the system. 9. CHECK FLUID LEVEL (See page SR-5 )

CHECK FLUID LEVEL Keep the vehicle level. With the engine stopped, check the fluid level in the oil reservoir. If necessary, add fluid. Fluid: ATF DEXRON® II or III HINT: Check that the fluid level is within the HOT LEVEL range on the reservoir. If the fluid is cold, check that it is within the COLD LEVEL range. (c) Start the engine and run it at idle. (d) Turn the steering wheel from lock to lock several times to boost fluid temperature. Fluid temperature: 80°C (176°F)

(e) Check for foaming or emulsification. If there is foaming or emulsification, bleed power steering system (See page SR-4 ).

Engine Idling

Engine Stopped R11562

With the engine idling, measure the fluid level in the oil reservoir. (g) Stop the engine. (h) Wait a few minutes and remeasure the fluid level in the oil reservoir. Maximum fluid level rise: 5 mm (0.20 in.) If a problem is found, bleed power steering system (See page SR-4 ). (i) Check the fluid level.
