Ford Focus Thermostat Housings & Filler Necks

A thermostat is one of the key components of the engine cooling system. Essentially, it’s a valve that opens or closes depending on the temperature of the liquid flowing through it. When the coolant is cold, the valve is closed, and the liquid circulates through the engine assembly alone. With the temperature growing, the thermostat progressively opens the valve allowing more coolant to enter the radiator. The thermostat housing plays an important role there. It’s a three-way tube making sure that the liquid flows in a right direction.

A thermostat housing may leak. It uses gaskets ensuring the perfect sealing as the tubing expands and shrinks due to changes in temperature. But those gaskets aren’t very durable. Made from soft materials, they gradually deteriorate while losing flexibility and ultimately allowing for leaks. They are especially susceptible to overheat. Hence, if the temperature gauge in your Focus even once approached the red zone, you’re likely to have impaired gaskets. And, in case your tubing is made of plastic, it can deform too. You can find high-quality replacements in our Ford Focus thermostat housing & filler necks inventory to solve your problems with overheating.
