Cooling System: Service and Repair

1. With engine off, add specified coolant concentrate to radiator, then add water until it reaches radiator filler neck seat.
2. Remove vent plug on water bypass elbow (located on intake manifold behind water outlet connection). Vent plug must be removed before radiator fill or engine may not fill completely. Do not turn plastic cap under vent plug or gasket may be damaged. Do not try to add coolant through vent plug hole. Install vent plug after filling radiator and before starting engine.
3. Install radiator pressure cap to first notch.
4. Start and idle engine until upper radiator hose is warm.
5. Carefully remove cap and top off radiator with water.
6. Install cap on radiator. Fill coolant recovery reservoir to FULL COLD mark with coolant, then add water to FULL HOT mark. This will ensure a proper mixture in coolant recovery bottle.
7. Check for leaks at radiator draincock, block plug and vent plug.
