2.
Remove the water inlet fitting (A), O-ring (B) and thermostat (C).
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 inlet fitting (A), O-ring (B) and thermostat (C).
Immerse the thermostat in water and gradually heat the water.
Check the valve opening temperature.
Valve opening temperature : 82±2°C (179.6±3.6°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 : 10mm(0.3937in) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
Place the thermostat (C) in thermostat housing with a new O-ring (B).
Place the thermostat with the jiggle valve (D) upward.
Install the water inlet fitting (A).
Tightening torque :
16.7 ~ 22.6N.m (1.7 ~ 2.3kgf.m, 12.3 ~ 16.6lb-ft)
Fill with engine coolant.
Start engine and check for leaks.
