2.
Remove the drive belt(A).
Drain 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 the drive belt(A).
Remove the water pump pulley(A).
Remove the water pump(A).
Disassembly of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.
Drain engine coolant so that its level would be under the thermostat height.
Remove the water inlet fitting(A), gasket and thermostat(B).
Drain the engine coolant.
Remove the radiator cap to speed draining.
Remove the radiator upper hose(A) and the breather hose(B).
Remove the radiator lower hose(A).
Disconnect the fan motor connector(A).
Remove the blower assembly(A) for cooling module.
Disconnect the ATF oil cooler hoses(A).
Remove the radiator upper bracket(A), then pull up the cooling module.
After pulling back the condenser fixing bracket(A), remove the radiator assembly.
Drain engine coolant.
Remove the air cleaner assemlby.
Disconnect the air cleaner hose(A) and breather hose(B).
Remove the accelerator cable(C).
Disconnect the powertrain control module(PCM) connector(D).
Remove the air cleanerassemlby(E).
Remove the engine coolant hose(A).
Remove the water temperature control assemlby(A).
To install, reverse the removal orders.
Clean the surface of the water temperature control assembly before installing.
Install the water pump.
Install the water pump(A) and a new gasket with the bolts.
Tighten the bolts with the order blow.
Install the water pump pulley(A) with the four bolts.
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
Tighten the bolts diagonally.
Install the drive belts.
Fill with engine coolant.
Start engine and check for leaks.
Recheck engine coolant level.
Place the thermostat in the block.
Install the thermostat(B) with the jiggle valve upward.
Install a new gasket to the thermostat(B).
Install the water inlet fitting(A).
Tightening torque :
18.6 ~ 23.5N.m (1.9 ~ 2.4kgf.m, 13.7 ~ 17.4lb-ft)
Fill with engine coolant.
Start engine and check for leaks.
Install the radiator.
Install the radiator upper bracket(A).
Tightening torque :
3.9 ~ 5.9N.m (0.4 ~ 0.6kgf.m, 2.9 ~ 4.3lb-ft)
Install the ATF(Automatic Transaxle Fluid) oil cooler hoses(A).
Connect the fan motor connector(A).
Install the radiator lower hose(A).
Connect the radiator upper hose(A) and the breather hose(B).
Fill with engine coolant.
Start engine and check for leaks.
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 heat the water.
Check the valve opening temperature.
Valve opening temperature : 82±1.5°C (179.6±2.7˚F)
Full opening temperature : 95°C (203˚F)
If the valve opening temperature is not as specified, replace the thermostat.
Check the valve lift.
Valve lift : 8mm(0.3in) or more at 95°C (203˚F)
If the valve lift is not as specified, replace the thermostat.
Disconnect the cooling fan motor connector.
Check that the radiator fan rotates when battery voltage is applied between the terminals.
