Scheme 1
Scheme 2
- Remove the radiator cap (A), wet its seal with engine coolant, then install it on the pressure tester (B) (commercially available).
- Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2 , 14-18 psi).
- Check for a drop in pressure.
- If the pressure drops, replace the cap.
Scheme 3
- Wait until the engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant to the top of the filler neck.
- Attach the pressure tester (commercially available) (A) to the radiator, and apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2 , 13.5-18 psi).
- Inspect for engine coolant leaks and a drop in pressure.
- Remove the pressure tester.
- Check for engine oil in the coolant and/or coolant in the engine oil.
- Install the radiator cap.
Scheme 4
- Disconnect the 2P connectors from the radiator fan motor and condenser fan motor.
- Test the motor by connecting battery power to terminal No. 2 and ground to terminal No. 1.
- If the motor fails to run or does not run smoothly, replace it.
