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.
•
Install the thermostat with the jiggle valve upward.
•
When assembling the thermostat, place the thermostat on the
housing with a protrusion of thermostat matching with a groove of the
housing and install the gasket and inlet fitting. Be careful the
thermostat doesn’t get out of the groove on the housing.
5.
Fill the engine coolant.
6.
Start the engine and check for leaks.
7.
Recheck the coolant level.
Inspection
1.
Immerse thermostat in water heated to over 95°C (203°F), then heat for at least 3 minutes to check valve lift.
•
Do not use water below 95°C (203°F).
•
Do not directly heat unit as this will damage thermostat.
