COOLING SYSTEM BLEED PROCEDURE

To be performed after servicing the cooling system.

1. Fill cooling system with a 50/50 mixture of antifreeze and water, to just below the filler neck.
2. Fill the coolant recovery reservoir to the specified fill mark on the outside of the reservoir.
3. Run engine with the radiator cap removed until normal operating temperature is achieved.
4. Set climate control to maximum heat and high blower.
5. With engine running at idle, add coolant to the radiator, until it reaches the bottom of the filler neck.
6. Replace the radiator cap. Arrows on the cap must line up with the coolant recovery reservoir hose.
7. Cycle the engine to 4000 RPM, then back to idle at least five times. This will help expel any air trapped in the system.
8. Verify heater operation.
9. Recheck coolant level in reservoir, add if necessary.
