  1. Remove the water pump (A) with water pump pulley.

Tightening torque : 7.8 - 11.8 N*m (0.8 - 1.2 kgf*m, 5.8 - 8.7 lb*ft)

  1. Remove the water pump gasket (A).

  1. Install in the reverse order of removal.

Warning

Install a new water pump gasket.

  1. Fill the engine coolant.

    (Refer to Cooling System - "Coolant")

  2. Start the engine and check for leaks.
  3. Recheck the coolant level.

Water Pump Cover

  1. Remove the engine room under cover.

    (Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

  2. Drain the coolant.

    (Refer to Cooling System - "Coolant")

  3. Disconnect the coolant hose (A).

  1. Remove the thermostat.

    (Refer to Cooling System - "Thermostat")

  2. Remove the heater pipe.

    (Refer to Cooling System - "Water Temperature Control Assembly")

  3. Remove the water pump.
  4. Remove the water pump cover (A).

Tightening torque : 18.6 - 23.5 N*m (1.9 - 2.4 kgf*m, 13.7 - 17.4 lb*ft)

  1. Install in the reverse order of removal.
  2. Fill the engine coolant.

    (Refer to Cooling System - "Coolant")

  3. Start the engine and check for leaks.

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.

Warning

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