Coolant Replacement
Refer to
Safety Precautions
on page 25.
Coolant should be replaced by your dealer, unless
you have the proper tools and service data and
are mechanically qualified. Refer to the Honda
Service Manual (page 174).
Coolant
Removing the radiator cap while the
engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.
WARNING
Cooling System Inspection
1. Check the cooling system for leaks (see the
Honda Service Manual for troubleshooting of
leaks).
2. Check the water hoses (1) for cracks,
deterioration, and radiator hose clamp 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 bleed hole (3) below the water
pump cover (4) for leakage. Check for signs
of seal leakage. A small amount of “weeping”
from the bleed hole is normal. See the Honda
Service Manual or consult your dealer for
replacing the water seal or the oil seal. Both
seals should be replaced at the same time.
