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 overflow tube (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 for leakage. Make sure the
hole remains open. If water leaks through the
check hole, the water pump seal is damaged.
If oil leaks through the check hole, the
transmission oil seal is damaged. See the
Honda Service Manual or consult your Honda
dealer for replacing the water pump seal or
the transmission oil seal. Both seals should
be replaced at the same time.
