Remove the water inlet fitting (A) and thermostat (B).
Disassembly of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.
Drain engine coolant so that its level would be under the thermostat height.
Remove the radiator lower hose.
(Refer to Cooling System - "Radiator Hose")
Remove the water inlet fitting (A) and thermostat (B).
Immerse the thermostat in water and gradually heat the water.
Check the valve opening temperature.
Valve opening temperature:

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.
Place the thermostat in the block.
Install the thermostat (B) with the jiggle valve upward.
