3. Remove the 4 bolts and pump pulley (A).





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





WATER TEMPERATURE CONTROL ASSEMBLY
1. Drain the engine coolant.
2. Remove air cleaner assembly.
3. Disconnect radiator upper and lower hose (A).





4. Disconnect ECT connector.

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.
