2.
Remove the thermostat (C) with its gasket (B) after taking off the water inlet fitting (A) from the water temperature control assembly.
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
Disassembly of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.
Drain the engine coolant so its level is below thermostat.
Remove the thermostat (C) with its gasket (B) after taking off the water inlet fitting (A) from the water temperature control assembly.
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
Installation is reverse order of removal.
Install the thermostat (C) with the jiggle valve upward.
Conform to what is described above because tension of the belt in this engine is higher than ones of other engines for preventing a slip.
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 : 10 mm (0.39in) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
