Removal and Installation
1.
Loosen the drain plug (A), and drain the coolant.
Remove the radiator cap to speed draining.

Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.
2.
Remove the drive belt (A).

3.
Remove the exhaust manifold heat protector (A).

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

4.
Remove the water inlet pipe bolt (A), and then remove the water pump (B) and the gasket.

Tightening torque:
A: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
B: 18.6 ~ 23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)

5.
Installation is in the reverse order of removal.
6.
Fill the radiator with coolant and check for leaks.
Bleed air from the cooling system.
-
Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.)
-
Turn off engine and let it cool down. Check the coolant level and add coolant if needed. This will allow trapped air to be removed from the cooling system.
-
Put the radiator cap on tightly, then run engine again 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.
A small amount of "weeping" from the bleed hole is normal.
