Water Pump Repair Procedures

Removal

1. 1
   Remove the engine compartment cover. (Refer to Engine and Transaxle Assembly - "Engine Compartment Under Cover")
2. 2
   Drain the engine coolant. (Refer to Cooling System — Engine Coolant)
3. 3
   Remove the drive belt. (Refer to Valve Timing System - "Drive Belt")
4. 4
   Remove the water pump pulley (A).

   

5. 5
   Remove the water pump (A) and gaskets (B).

   

   

Inspection

1. 1
   Inspect each component for cracks, damage, or wear, and replace the water pump assembly if necessary.
2. 2
   Inspect the bearing for damage, abnormal noise, and rough rotation, and replace the water pump assembly if necessary.
3. 3
   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.

Installation

1. 1
   Install the water pump (A) with new gaskets (B).

   

   

   Clean the mating surface before assembly. Always use new gaskets. Always use a new stud bolt (bolt C).

   Tightening torque A(3EA): 9.8 ~ 11.8 N·m B(1EA): 9.8 ~ 11.8 N·m C(1EA): 21.6 ~ 26 N·m — new bolt D(1EA): 9.8 ~ 11.8 N·m E(1EA): 9.8 ~ 11.8 N·m F(1EA): 9.8 ~ 11.8 N·m G(4EA): 21.6 ~ 24 N·m

   

2. 2
   Install the water pump pulley (A).

   Tightening torque: 7.8 ~ 9.8 N·m

   

3. 3
   Install in the reverse order of removal.
4. 4
   Fill the radiator with engine coolant and check for leaks. (Refer to Cooling System - "Engine Coolant")
