Mazda CX-5 Service & Repair Manual: Thermostat
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.
Thermostat Removal/Installation
