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
Honda All Season Antifreeze/
Coolant Type 2.
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). Turn
the temperature control dial to
maximum heat. Turn off the
ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.
2. Remove the radiator cap.
