Removal
Disassembly of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.
1. | Drain engine coolant so that its level would be under the thermostat height.
2. | Remove the radiator lower hose.
3. | Remove the water inlet fitting (A) and thermostat (B).
Inspection
1. | Immerse the thermostat in water and gradually heat the water.
2. | 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.
3. | 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.
Installation
1. | Place the thermostat in the block. Install the thermostat (B) with the jiggle valve upward.
2. | Install the water inlet fitting (A).
Tightening torque : 18.6 ~ 23.5N.m (1.9 ~ 2.4kgf.m, 13.7 ~ 17.4lb-ft)
3. | Fill with engine coolant.
4. | Start engine and check for leaks.
