- Installation is performed in the reverse order of removal, using a new water pump gasket.
- Fill the engine coolant.
- Start the engine and check for leaks.
- Recheck the coolant level.
Inspection
- Inspect each component for cracks, damage, or wear, and replace the water pump assembly if necessary.
- Inspect the bearing for damage, abnormal noise, and rough rotation, and replace the water pump assembly if necessary.
- Check for coolant leakage. If coolant leaks from the hole, the seal is damaged. Replace the water pump assembly.
A small amount of "weeping" from the weep hole is normal.
