Water Pump Cleaning and Inspection





Inspect the water pump (300) for the following conditions:

* Gasket sealing surfaces for excessive scratches or gouging
* Restrictions within the coolant passages
* Excessive side-to-side play in the pulley shaft
* A loose belt pulley or a pulley with excessive wear in the belt tracking area
* Leakage at the vent hole
A stain around the vent hole is acceptable. If leakage occurs, such as dripping with the engine running or the cooling system pressurized, replace the water pump.
