Water Pump: Service and Repair

4. Remove the water pump(A) and gasket(B).





CAUTION:
Do not reuse the water pump gasket disassembled.

INSTALLATION

INSPECTION


WATER PUMP
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.
3. Check for coolant leakage. If coolant leaks from hole, the seal is defective. Replace the coolant pump assembly.

NOTE:
A small amount of "weeping" from the bleed hole is normal.
