4.Disconnect the ECT(Engine Coolant Temperature) sensor connector.
5. Remove the coolant hose related to the heater hoses and the ECT(Engine Coolant Temperature) system.
6. Remove wiring protector.
7. Remove water temperature control assembly(A) and the gaskets(B).
8.Remove the water pipe(A).
THERMOSTAT
Removal 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. Remove the coolant inlet pitting(A) and the thermostat(B).
