Scheme 21

1. Remove the radiator cap (A), wet its seal with engine coolant, then install it on a commercially available pressure tester (B).
2. Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2 , 14-18 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Scheme 22

1. 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.
2. Attach a commercially available pressure tester (A) to the radiator, and apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2 , 14-18 psi).
3. Inspect for engine coolant leaks and a drop in pressure.
4. Remove the tester, and reinstall the radiator cap.

Scheme 23

1. Disconnect the 2P connectors from the radiator fan motor (A) and condenser fan motor (B).
2. Test the motor by connecting battery power to the B terminal and ground to the A terminal.
3. If the motor fails to run or does not run smoothly, replace it (see «Radiator & Fan Replacement»(ref-173994-S19391197972005041500000) ).
