Water Pump Repair Procedures

Removal and Installation

1. 1
   Drain the engine coolant. (Refer to Cooling System — Engine Coolant)
2. 2
   Remove the drive belt. (Refer to Valve Timing System - "Drive Belt")
3. 3
   Remove the water pump pulley (A).

   Tightening torque: 9.8 ~ 11.8 N·m

   

4. 4
   Remove the water pump assembly (A) with the gasket (B).

   Tightening torque: 9.8 ~ 11.8 N·m

   

5. 5
   Install in the reverse order of removal.

   Install a new water pump gasket.

6. 6
   Fill the engine with engine coolant. (Refer to Cooling System - "Engine Coolant")
7. 7
   Start the engine and check for leaks.
8. 8
   Recheck the coolant level.

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.
