Remove the water pump. Refer to Disassembly and Assembly, "Water Pump - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The water pump seal can be replaced without removing the water pump from the engine.Note: An intermittent leakage of a small amount of coolant from the hole in the water pump housing is not an indication of a water pump seal failure. This is required to provide lubrication for the seal. Do not replace the water pump seal unless a large amount of leakage or a constant flow of coolant is draining from the water pump housing.
