Do not add any rust inhibitors or
other additives to your car's cooling
system. They may not be compatible
with the coolant or engine compo-
nents.
Replacing Engine Coolant
The cooling system should be
completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use
Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance
done by a skilled mechanic.
1. Turn the ignition ON (II). Slide
the heater temperature control
lever to maximum heat. Turn off
the ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.
