Remove drive belt(A).
Drain the engine coolant.
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.
Remove drive belt(A).
Remove the 4 bolts and pump pulley(A).
Remove the water pump(A) and gasket.
Drain the engine coolant.
Remove air cleaner assembly.
Disconnect radiator upper and lower hose(A).
Disconnect WTS connector.
Disconnect heater hose, water vent hose and water hose from water temperature control assembly.
Remove wiring protector.
Remove water temperature control assembly(A).
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.
Drain engine coolant so its level is below thermostat.
Remove water inlet(A) and thermostat(B).
Drain the engine coolant.
Remove the air duct(A).
Disconnect radiator upper and lower hoses(A).
Disconnect transaxle oil cooler hoses.(Refer to TR group)
Disconnect the radiator fan connector(A).
Remove the radiator bracket(A).
Remove the radiator(A).
Remove the radiator fan(A).
Install the water pump(A) and a new gasket(B) with 12 bolts.

Install the 4 bolts and pump pulley(A).
Tightening torque
7.84 ~ 9.80Nm (0.8 ~ 1.0kgf.m, 5.78 ~ 7.23lb-ft)
Install drive belt(A).
Fill with engine coolant.
Start engine and check for leaks.
Recheck engine coolant level.
Make clean the contact face before assembly.
Install water temperature control assembly(B) and new gasket(A).
Tightening torque
18.62 ~ 23.52Nm (1.9 ~ 2.4kgf.m, 13.74 ~ 17.36lb-ft)
Use new O-rings(C) when reassembling.
Connect water hoses to the water temperature control assembly.
Install wiring protector.
Connect WTS connector.
Connect radiator upper and lower hose(A).
Install air cleaner assembly.
Fill with engine coolant.
Start engine and check for leaks.
Recheck engine coolant level.
Place thermostat in thermostat housing.
Install the thermostat with the jiggle valve upward.
Install a new thermostat(B).
Install water inlet(A).
Tightening torque
16.66 ~ 19.60Nm (1.7 ~ 2.0kgf.m, 12.30 ~ 14.47lb-ft)
Fill with engine coolant.
Start engine and check for leaks.
Install the radiator fan(A) to the radiator.
Install the radiator(A).
Install the radiator bracket(A).
Reconnect the radiator fan connector(A).
Connect transaxle oil cooler hoses.(Refer to TR group)
Connect radiator upper and lower hoses(A).
Install the air duct(A).
Fill with engine coolant.
Start engine and check for leaks.
Recheck engine coolant level.
Check each part for cracks, damage or wear, and replace the coolant pump assembly if necessary.
Check the bearing for damage, abnormal noise and sluggish rotation, and replace the coolant pump assembly if necessary.
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.
Immerse the thermostat in water and gradually heatthe water.
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.
Check the valve lift.
Valve lift : Min. 10mm (0.4in.) at 95°C (205°F)
If the valve lift is not as specified, replace the thermostat.
