Cooling System 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. This coolant is a mixture of 50 percent anti-freeze and 50 percent water. Premixing in not required. Draining the coolant requires access to the underside of the vehicle. Unless you have the tools and knowledge, you should have this maintenance done by a skilled mechanic. DRAIN PLUG DRAIN BOLT 1. Turn the ignition ON (II). Turn the heater temperature control dial fully clockwise. Turn the ignition off. Open the hood. Make sure the engine and radiator are cool to the touch. 2.
