Water Pump: Service and Repair

Removal

Water Pump

3. Remove the water pump pulley(A).




4. Remove the water pump(A).





Water Temperature Control Assembly
1. Drain engine coolant.
2. Remove the air cleaner assembly.




3. Remove the water temperature control assembly(A).

Tightening torque :
9.8 - 11.7N.m (1.0 - 1.2kgf.m, 7.2 - 8.7lb-ft)




4. To install, reverse the removal orders.

CAUTION:
Clean the surface of the water temperature control assembly before installing.

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

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