Repair Procedures

Removal

Water Pump
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 4 bolts and pump pulley.
(2) Remove the 2 bolts(C), then remove the alternator brace (A).
(3) Remove the water pump (B) and gasket.





Thermostat

NOTE:
Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove the thermostat, even if the engine tends to overheat.

1. Drain engine coolant so its level is below thermostat.
2. Remove water inlet (A), gasket and thermostat.





Radiator
1. Remove the radiator cap to speed draining.
2. Loosen the radiator drain plug (A) and drain engine coolant.




3. Disconnect the terminals(A) and remove the battery(B).




4. Remove the air duct (A).




5. Remove the air cleaner assembly.
(1) Disconnect the power train module (PCM) connector (A).
(2) Disconnect the intake hose (B).
(3) Remove the air cleaner assembly (C).




6. Disconnect the auto transaxle fluid (ATF) hose (A).




7. Disconnect the fan motor connector (A) and remove the radiator mounting bracket (B).




8. Remove the blower assembly(A).




9. After pulling back the condenser fixing bracket(A), remove the radiator assembly.






Inspection

Water Pump
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 coolant pump assembly.

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

Thermostat
1. Immerse the thermostat in water and gradually heat the water.




2. Check the valve opening temperature.

Valve opening temperature :82 °C(177 °F)
Full opening temperature :95 °C(205 °F)




If the valve opening temperature is not as specified, replace the thermostat.
3. Check the valve lift.

Valve lift :8mm(0.3in.) or more at 95 °C(205 °F)

If the valve lift is not as specified, replace the thermostat.

Installation
