Water Pump: Service and Repair

COMPONENTS:

3. Remove exhaust manifold.
4. Remove water inlet pipe nut.





5. Remove the water pump (A).

INSPECTION
1. Check each part for cracks, damage or wear, and replace the coolant pump assembly if necessary.
2. Check the bearing for damage, abnormal noise and sluggish rotation, and replace the coolant pump assembly if necessary.
