Removal and Installation
Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove the thermostat, even if the engine tends to overheat.
1. | Drain engine coolant so its level is below thermostat.
2. | Remove the radiator lower hose (A).
3. | Remove water inlet fitting (A), gasket (B) and thermostat (C).
Tightening torque : 7.8 ~ 11.8N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7lb-ft)
4. | Installation is reverse order of removal.
Install the thermostat with the jiggle valve upward.
5. | Fill the engine coolant.
6. | Start the engine and check for leaks.
7. | Recheck the coolant level.
Inspection
1. | Immerse the thermostat in water and gradually heat the water.
2. | Check the valve opening temperature.
Valve opening temperature : 82°C (177°F) Full opening temperature : 95°C (205°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 (205°F)
If the valve lift is not as specified, replace the thermostat.
