trical parts or the paint. lf any coolant spills, rinse it off
immediately.
1. Slide the heater temDerature control lever to maxi-
mum heat.
Make sure the engine and radiator are cool to the
touch.
2. Remove the radiator cap.
3. Loosen the drain plug, and drain the coolant.
4. Remove the drain bolt from the cvlinder block.

7. Remove, drain and reinstall the reservoir. Fillthe tank
halfway to the MAX mark with water, then up to
MAX mark with antifreeze.

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.

these items:
. Apply sealant to the grommets
. Do not interchange the inlet and outlet hoses.
Make sure that the hose clamps are secure.
. Loosen the bleed bolt on the engine and refill the
radiator and coolant reservoir with the proper
engine coolant minure (see section 10).
Tighten the bleed bolt when all the trapped air
has escaped and engine coolant begins to flow
from it (see section 10).
. Connect all cables and make sure they are prop-
erly adjusted (see page 2'l-271.

. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-1344) to avoid leakage.
a Do not damage the radiator and condenser fins
when installing the condenser.
o Be sure to install the condenser mount cushions
securely into the holes.
. Charge the system {see page 22-39) and test its
