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. |
