Coolant Level Servicing

NOTE: The cooling system is closed and designed to maintain coolant level to the top of the radiator.

When servicing requires a coolant level check in the radiator, the engine must be off and not under pressure. Drain several ounces of coolant from the radiator drain cock while observing the Coolant Recovery Container. Coolant level in the container should drop slightly. Then remove the radiator cap. The radiator should be full to the top. If not, and the coolant level in the recovery container is at the ADD mark there is a air leak in the recovery system. Check hose or hose connections to the recovery container, radiator filler neck or the pressure cap seal to the radiator filler neck for leaks.
