Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Water pumps may leak as a result of damaged face seals. Relative movement between the shaft and the housing may allow the drive shaft to contact the face seal in the water pump. If contact occurs, the face seal will be damaged, and very early hour failures can result.
Note: Do not lift the auxiliary water pump by the shaft. Do not bump the shaft when installing the auxiliary water pump onto the engine.
