Water Pump: Testing and Inspection
WATER PUMP FLOW
To determine whether coolant is flowing through the cooling system, use one of the following procedures:
PREFERRED METHOD
WARNING: Do not remove the cooling system pressure cap or any hose with the system hot and under pressure because serious burns from
coolant can occur.
-
2.0L/2.4L: Remove pressure cap when engine is cold. Remove small amount of coolant. Idle engine until thermostat opens. You should observe
coolant flow while looking down the filler neck. Once flow is detected install the pressure cap. Replace removed coolant into coolant recovery
container.
-
2.7L: Start engine, coolant flow should be observable in coolant pressure container when revving the engine.
ALTERNATIVE METHOD
-
If engine is cold, idle engine until normal operating temperature is reached. Feel the upper radiator hose. If it is hot, coolant is circulating.
