- 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. |
