8.Mix the recommended antifreeze with an equal
amount of water in a clean container.
NOTE:
a Use only genuine Honda antifreeze/coolant.
a For best corrosion protection, the coolant concen-
tration must be maintained year-round at 500,6
minimum. Coolant concentrations less than 507o
may not provide sufficient protection against cor,
rosion or freezing.
a Coolant concentrations greater than 60% will im-
pair cooling efliciency and are not recommended.
CAUTION:
a Do not mix different brands of anti-lrcezel
coolants.
a Do not use additional rust inhibitots or anti-tustproducts; they may not be compatible with the
coolant.

9.Pour coolant into the radiator up to the base of the
tiller neck.
10. Startthe engine and let jt run until itwarmsup(the
radiator fan comes on at least twice).
1 1 . Turn olf the engine. Check the level in the radiator,
add coolant if needed.
'12. Put the radiator cap on tightly, then run the engine
again and check for leaks.

Cap Testing
1.Remove the radiator cap, wet its seal with engine
coolant, then install it on the pressure tester.
Apply a pressure of:
93 123 kPa(0.95 1.25 kgf/cm', 13.5 17.8 psi)
Check for a drop in pressure.

Pressure Testing
1. Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top ot the filler neck.
2. Attach the pressure tester to the radiator and apply
a pressure of:
93 123 kPa(O.95- 1.25 kgf/cmr, 13.5-'17.8 psi)
3. Inspect lor engine coolant leaks and a drop inpressure.
4. Remove the tester and reinstall the radiator cap.
NOTE:
a Check for engine oil in the engine coolant and/orcoolant in the engine oil.a Check for ATF in the engine coolant and/orcoolant in the ATF {A/T}.

Inspection
Remove the timing belt (81881 engine: see page 6-10, B'l8Cl,818C5 engines: see page 6-48).
Tu.n the water pump pulley counterclockwise.Check that it turn freely.
Check for sign6 of seal leakage.
NOTE: A small amount of "weeping" trom thebleed hole is normal.
BLEED HOLE
Remove the timing belt (81881 engine: see page 6-
10,818C1, Bl8C5 engines: see page 6-48).
Remove the camshaft pulleys and the back cover(B'1881 engine: see page 6-20, 818C1, 818C5
engines: see page 6-60).
Remove the water pump by removing flve bolts.
NOTE: Inspect, repair and clean the O-ring groove
and mating surface with the cylinder block,
