Tightening torque :
7.8 ~ 11.8N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7lb-ft)
Installation is reverse order of removal.
Install the thermostat with the jiggle valve upward.
Fill the engine coolant.
Start the engine and check for leaks.
Recheck the coolant level.
Immerse the thermostat in water and gradually heat the water.
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.
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.
