THERMOSTAT [SKYACTIV-G 2.5]

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 {177—182°F}, the thermostat valve starts to open and the engine coolant passed through the radiator flows to the engine.
