What is a Thermostat Housing?
A thermostat housing is a crucial component of a car’s cooling system, which is vital in regulating the engine temperature. It is typically made of metal or plastic and is responsible for housing the thermostat, which controls the flow of coolant through the engine.
The purpose of a thermostat housing is to provide a secure and sealed enclosure for the thermostat. The thermostat itself is a valve that opens and closes depending on the engine’s temperature. When closed, it prevents coolant from entering the engine, allowing it to warm up quickly. Once the desired temperature is reached, it opens to allow the coolant to circulate and maintain a consistent operating temperature.
In Mazda vehicles, the location and design of their thermostat housings may vary depending on the model and year. However, they all serve an essential function in keeping your engine running smoothly and efficiently.
One common type of Mazda thermostat housing is an integrated housing assembly. This type combines the upper radiator hose connection and the thermostat into one unit. It can be found in models such as the Mazda6, CX-7, CX-9, and MX-5 Miata.
