Dorman Engine Coolant Water Outlet Thermostat Housing

The Dorman engine coolant water outlet thermostat housing, also called a thermostat housing or coolant outlet, is a replacement part for the engine cooling system. It holds the thermostat in place and gives the coolant a sealed path out of the engine and toward the radiator. A cracked, corroded, or leaking housing can cause coolant loss and overheating, so replacing it helps restore reliable cooling performance.

Key Features:

• Replaces a worn, cracked, or corroded original housing
• Designed to restore proper thermostat seating and a leak-free coolant connection
• Built as a direct-replacement part to match the form and function of the original
• Available in multiple configurations, each with its own part number
• Backed by Dorman's reputation as a leading supplier of aftermarket replacement parts

Dorman is known for solving common repair problems and for offering replacement parts that are practical to install. Replacing the housing together with the thermostat and fresh coolant is a common way to get a complete, lasting repair. Select the child item that matches your application to see its specific details.
