Removal and Installation
WARNING: This page is about a different variant/trim than selected.
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.
- Drain engine coolant so its level is below thermostat.
(Refer to Cooling System - "COOLANT ")
- Disconnect the radiator lower hose.
(Refer to Cooling System - "Radiator ")
- Remove the water inlet fitting (A) and thermostat (B).
Tightening torque: 18.6 ~ 23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)
- Remove the intake manifold.
(Refer to Intake and Exhaust System - "INTAKE MANIFOLD ")
- Remove the bypass hose (A).
- Unfasten the heater pipe mounting bolts (B) and then remove the heater pipe.
Tightening torque: 19.6 ~ 23.5 N.m (2.0 ~ 2.4 kgf.m, 14.5 ~ 17.4 lb-ft)
NOTE:- Do not reuse the seal bolts.
- Install in the reverse order of removal.NOTE:
- 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 inlet fitting. Be careful the thermostat doesn't get out of the groove on the housing.
- Clean surface on the rubber packing contact surface.
- Fill the engine coolant.
(Refer to Cooling System - "COOLANT ")
- Start the engine and check for leaks.
- Recheck the coolant level.
