Inspection Procedure 2: Engine Overheating
DIAGNOSIS
STEP 1. Remove the radiator cap and check for coolant contamination.
Q. Is the coolant contaminated with rust and oil?
YES Replace it (Refer to Engine Coolant Change) [2.0L ENGINE Non-turbo, 2.4L ENGINE] or (Refer to Engine Coolant Change) [2.0L ENGINE Turbo].
NO There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
NOTE:
Be sure that the cap is clean before testing. Rust or other foreign material on the cap seal will cause an improper reading.
(1)Use a cap adapter to attach the cap to the tester.
(2)Increase the pressure until the gauge indicator stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)
Q. Does the reading remain at or above the minimum limit?
YES Go to Step 3.
NO Replace the radiator cap. Then go to Step 5.
STEP 3. Check thermostat operation.
Refer to Testing and Inspection.
Q. Does the thermostat operate correctly?
