Dorman Engine Coolant Thermostat Housing Assembly

The Dorman Engine Coolant Thermostat Housing Assembly is a replacement thermostat housing, also called a thermostat housing or coolant outlet, designed to restore proper engine cooling system operation. The housing holds the thermostat and directs coolant flow between the engine and the radiator. It helps the engine reach and hold its correct operating temperature.

Key Features:

• Replaces a cracked, warped, corroded or leaking factory housing
• Built to match the form, fit and function of the original part
• Gives a secure seal at the mating surfaces to help prevent coolant leaks and overheating
• Many assemblies are designed to improve on original-equipment weak points, such as aging plastic or corrosion-prone materials
• Supports reliable thermostat operation and consistent coolant flow

A failing thermostat housing can cause coolant loss, overheating, poor heater performance and engine damage. Replacing it helps protect the cooling system.
