Remove the water pump pulley(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 the drive belts.
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 the engine coolant so its level is below thermostat.
Remove the water outlet fitting(A), gasket and thermostat.
Drain the engine coolant.
Remove the radiator cap to speed draining.
Remove the upper radiator hose(A).
Remove the lower radiator hose(A).
Disconnect the fan motor connector(A).
Remove the radiator upper bracket, then pull up the radiator.
Remove the cooling fan assembly (A).
Install the water pump(A) and a new gasket.
Tightening torque :
19.6 ~ 24.5N.m (2.0 ~ 2.5kgf.m, 14.5 ~ 18.1lb-ft)
Apply coolant to the O-ring before installing the water pump.
Install the water pump pulley(A).
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
Install the drive belts.
Fill with engine coolant.
Start engine and check for leaks.
Recheck engine coolant level.
Place the thermostat in thermostat housing with new gasket.
Install the water outlet fitting(A).
Tightening torque :
19.6 ~ 24.5N.m (2.0 ~ 2.5kgf.m, 14.5 ~ 18.1lb-ft)
Fill with engine coolant.
Start engine and check for leaks.
Install the cooling fan assembly (A).
Tightening torque :
6.9 ~ 10.8N.m (0.7 ~ 1.1kgf.m, 5.1 ~ 8.0lb-ft)
Install the radiator.
Install the radiator upper bracket.
Connect the fan motor connector( A).
Install the lower radiator hose(A).
Install the upper radiator hose(A).
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 : 85±1.5°C (185.0±2.7°F)
(Measurement lift : 0.35mm(0.0138in))
Full opening temperature : 100°C (212°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 100°C (212°F)
If the valve lift is not as specified, replace the thermostat.
Disconnect the cooling fan motor connector.
Check if motor speed is low when power and ground are connected to the NO.1 and NO.3 terminals.
Check if motor speed is high when power and ground are connected to the NO.2 and NO.3 terminals.
