Cooling System Inspection
1. Check the cooling system for leaks (see the
Honda Service Manual for troubleshooting of
leaks).
2. Check water hoses (1) for cracks,
deterioration, and clamp bands for looseness.
3. Check the radiator mount for looseness.
4. Make sure the siphon hose (2) is connected
and not clogged.
5. Check the radiator fins for clogging.
6. Check the water leakage check hole (3) below
the water pump cover (4) for leakage. Make
sure the hole remains open. If water leaks
through the check hole, the mechanical seal is
damaged. If oil leaks through the check hole,
the engine oil seal is damaged. See the Honda
Service Manual or consult your Honda dealer
for replacing the mechanical seal or the engine
oil seal. Both seals should be replaced at the
same time.

down before removing the radiator cap.
