Remove the water pump (A).
Tightening torque :
19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 Ib-ft)
When installing the water pump, replace the o-ring with a new one.
Install in the reverse order of removal.
Fill the radiator with coolant.
(Refer to Cooling System - "Coolant")
Start the engine and check for leakage.

Remove the engine room under cover.
Drain the coolant.
(Refer to Cooling System - "Coolant")
Remove the air control valve.
(Refer to Engine Control/Fuel System - “Air Control Valve”)
Disconnect the radiator lower hose (A).
Disconnect the heater hoses (A).
Remove the EGR cooler.
(Refer to Intake And Exhaust System - “EGR Cooler”)
Unfasten the oil feed pipe bracket bolt.
Tightening torque :
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
Disconnect the oil cooler return hose (A).
Remove the water return pipe (A).
Tightening torque :
19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 Ib-ft)

Fill the radiator with coolant.
(Refer to Cooling System - "Coolant")
Start the engine and check for leakage.
Check each part for cracks, damage or wear, and replace the water pump assembly if necessary.
Check the bearing for damage, abnormal noise and sluggish rotation, and replace the water pump assembly if necessary.
Check for coolant leakage. If coolant leaks from hole, the seal is defective. Replace the water pump assembly.
A small amount of "weeping" from the bleed hole is normal.
