Cooling System: Overview Honda Pilot II

Scheme 1

Scheme 2

1. Wait until the engine is cool, then carefully remove the radiator cap (A). Wet the radiator cap 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 , 13.5-18 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Scheme 3

1. Wait until the engine is cool, then carefully remove the radiator cap, and fill the radiator with engine coolant to the base 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, then reinstall the radiator cap.

Scheme 4

1. Disconnect the 2P connectors from the radiator fan motor (A) and the condenser fan motor (B).
2. Test each motor by connecting battery power to terminal No. 2 and ground to terminal No. 1.
3. If either motor fails to run or does not run smoothly, replace it (see «RADIATOR AND FAN REPLACEMENT»(ref-333555-S21535150732009072100000) ).
