Repair Procedures
Removal
1. Drain the engine coolant.
WARNING:
System is under high pressure when the engine is hot. To avoid danger of releasing scalding engine coolant, remove the cap only when the engine is cool.
2. Remove drive belts.
3. Remove the timing belt and the timing belt idler.
4. Remove the water pump.
(1) Remove the bolts (D), then remove the alternator brace (A).
(2) Remove the bolts (C), then remove the water pump (B) and gasket.
Inspection
1. Check each part for cracks, damage or wear, and replace the coolant pump assembly if necessary.
2. Check the bearing for abnormal noise and sluggish rotation, and replace the coolant pump assembly if necessary.
3. Check for coolant leakage. If coolant leaks from hole, replace the water pump assembly.
NOTE:
A small amount of "weeping" from the bleed hole is normal.
Installation
1. Install the water pump.
(1) Install the water pump (B) and a new gasket with the 3 bolts (C, D).

Bolts (D) : 19.6 - 26.5Nm (2.0 - 2.7kgf.m, 14.5 - 19.5lb-ft)
(2) Install the alternator brace (A) with the 2 bolts (E).
Tightening torque
19.6 - 23.5Nm (2.0 - 2.4kgf.m, 14.5 - 17.4lb-ft)
2. Install the timing belt idler and the timing belt.
3. Install the water pump pulley.
4. Install drive belts.
5. Tighten the bolts on the water pump pulley.
Tightening torque
7.8 - 9.8Nm (0.8 - 1.0kgf.m, 5.8 - 7.2lb-ft)
6. Fill with engine coolant.
7. Start engine and check for leaks.
8. Recheck engine coolant level.
