Water Necks - Thermostat Housings

Water Necks - Thermostat Housings are an important component of your vehicle's engine cooling system. Also commonly known as a thermostat housing or water outlet, this part holds the thermostat in place, regulating the flow of coolant between the engine and the radiator. The thermostat is the valve that opens and closes based on temperature to ensure your engine reaches and maintains its optimal operating temperature.

Your vehicle's water necks and thermostat housings can be made from various materials, including plastic, aluminum, or steel. Over time, these parts can become worn out or damaged from age, heat, and vibration, which can lead to coolant leaks. If you notice a coolant leak or your engine temperature gauge is reading higher or lower than normal, it may be time for a thermostat housing replacement.
