Dorman Engine Coolant Thermostat Housing Assembly with Sensor

The Dorman Engine Coolant Thermostat Housing Assembly with Sensor is a replacement thermostat housing (also called a water outlet or coolant outlet) designed to restore reliable engine coolant flow and temperature control. It replaces cracked, warped, leaking or corroded original housings, which commonly fail with age and repeated heat cycling.

Key Features:

• Replacement thermostat housing assembly that includes an integrated coolant temperature sensor
• Helps restore proper coolant circulation and consistent engine operating temperature
• Designed to address leaks, seepage and housing damage that can lead to overheating
• Engineered to match the form, fit and function of the original equipment part
• Built to hold up to continuous heat, pressure and coolant exposure
• Supports accurate temperature readings for the engine computer and gauge

A failing thermostat housing can cause coolant loss, overheating, poor heater performance and check engine lights. Replacing it with a complete assembly that includes the sensor simplifies the repair. Dorman is a long-established aftermarket brand known for hard-to-find replacement parts and practical, repair-focused solutions. Replace the gasket or seal and refill the coolant as part of the repair, following the vehicle manufacturer's service procedures.
