Draining and Filling

WARNING: DO NOT OPEN THE COOLING SYSTEM WHILE IT IS HOT OR ENGINE IS RUNNING.

CAUTION: Coolant must be recovered in a suitable clean container for reuse. If coolant is contaminated it must be recycled or disposed of properly.

NOTE: About 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.





1. Release pressure in the cooling system by slowly turning the radiator cap one half to one turn counterclockwise to the first step on the filler neck. When the pressure has been released, remove the radiator cap.

NOTE: When filling a crossflow radiator, allow time for the coolant to flow through the radiator tubes to fill both tanks. Use the following steps to remove air from the cooling system and to insure that filling procedure is complete.





6. Install the engine block drain plug.





7. Close the radiator draincock and lower the vehicle.
8. Add the proper coolant mixture (50-50 mix) to the radiator and radiator coolant recovery reservoir.
