INSPECTION
1. | Drain the coolant so its level is below thermostat.
2. | Remove the inlet fitting and gasket.
3. | Remove the thermostat.
4. | Immerse thermostat in hot coolant to check proper valve opening temperature. Replace if necessary.
Valve opening temperature : 82 °C (177 °F) Full opening temperature : 95 °C (205 °F)
COOLANT TEMPERATURE SENSOR
1. | Heat the sensor by submerging it in hot engine coolant.
2. | Check that the resistance is within the specified range.
Resistance At : 20 °C (68 °F) : 2.31 ~ 2.59kg
REASSEMBLY
1. | Check that the flange of the thermostat is correctly seated in the socket of the thermostat housing.
2. | Install a new gasket and the coolant inlet fitting.
3. | Refill the system with clean coolant.
Tightening torque Coolant temperature sensor : 20 ~ 40Nm (200 ~ 400kg.cm, 15 ~ 30lb.ft)
