- Remove the old gasket material
from the water pump sealing surfaces.
 
- Clean all excess dirt and debris from the water pump housing.
 
- Inspect the water pump for the following:
 
| •  | Gasket sealing surfaces for excessive scratches or gouging | 
 
| •  | Restrictions within the internal coolant passages | 
 
| •  | Excessive side-to-side play in the pulley shaft | 
 
| •  | Leakage at the water outlet housing or rear cover gasket | 
 
| •  | Leakage at the water pump vent hole | 
 
| •  | A stain around the vent hole is acceptable. If leakage occurs (dripping)
with the engine running and the cooling system pressurized, replace the water
pump. |
