Note: The water pump seal can be replaced without removing the water pump from the engine. An intermittent leakage of a small amount of coolant from the hole in the water pump housing will exist. This is not a sign of a failure of the seal. This is required to provide lubrication for the seal. Replace the water pump seal only if a large amount of leakage is observed.

1. Remove O-ring seal (1) from the adapter.

2. Remove adapter (2) from the housing. Remove the O-ring seal from the outside diameter of the adapter.

3. Remove bolt (3) and the retainer that holds the impeller on the shaft.
