INSPECT FOR ENGINE OIL LEAK
INSPECT FOR ENGINE COOLANT LEAK
Remove the radiator cap.
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
Install the radiator cap.
BLEED POWER STEERING SYSTEM
Check the fluid level Click here.
Jack up the front of the vehicle and support it with stands.
Turn the steering wheel.
With the engine stopped, turn the steering wheel slowly from lock to lock several times.
Lower the vehicle.
Start the engine.
Run the engine at idle for a few minutes.
Turn the steering wheel.
With the engine idling, turn the steering wheel left or right to the full lock position and keep it in that position for 2 to 3 seconds, then turn the steering wheel to the opposite full lock position and keep it there for 2 to 3 seconds (*1).
Repeat this procedure (*1) several times.
Stop the engine.
Check for foaming or emulsification.
Tech Tips
If the system has to be bled twice because of forming or emulsification, be sure to check for fluid leaks in the system.
