Purpose, Function
When the engine coolant temperature is low, the thermostat blocks the engine coolant passage between the radiator and engine. As a result, because engine coolant cycles without passing through the radiator, warming is promoted.
Construction
The thermostat is installed to the rear part of the cylinder head.

The thermostat has the following parts:

Operation
1. When the engine coolant temperature decreases, the thermostat valve closes and engine coolant circulates without passing through the radiator.

2. When the engine coolant temperature is 80.5—83.5°C, the thermostat valve starts to open and the engine coolant passed through the radiator flows to the engine.
