Removal and Installation
NOTE
Disassembly 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. Disconnect the radiator lower hose (A).

3. Remove water inlet fitting (C), gasket (B) and thermostat (A).
Tightening torque: 7.8 ~ 11.8N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7lb-ft)

4. Installation is reverse order of removal.
CAUTION
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 +- 1.5ºC (179.6 +- 2.7ºF)
Full opening temperature: 95ºC (203ºF)
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 95ºC (203ºF)
If the valve lift is not as specified, replace the thermostat.
