Dorman Engine Coolant Thermostat Housing Assembly with Thermostat

The Dorman engine coolant thermostat housing assembly with thermostat is a complete replacement solution for restoring proper engine temperature control and a leak-free cooling system. Also known as a thermostat housing, water outlet, or coolant outlet assembly, this part holds the thermostat in place and directs coolant flow between the engine and the radiator.

Key Features:

• Includes a matched thermostat with the housing, so you can replace both parts at once
• Replaces a worn, cracked, corroded, or leaking housing, which can cause coolant loss and overheating
• Built to help the engine reach and hold its correct operating temperature
• Designed to match the form, fit, and function of the original part
• Often includes updated materials or design improvements over the original housing to resist the cracking and warping that plague some factory housings
• Gasket or seal included where the application requires it

A failing thermostat housing can cause overheating, coolant leaks, poor heater performance, and inconsistent engine temperature. Replacing the housing and thermostat together restores reliable cooling system operation and saves a second repair later. Dorman is a long-time supplier of aftermarket replacement parts, and this line is designed for straightforward installation.
