Cooling System Function

The thermostat housing routes coolant through the engine cooling system and provides the mounting point for the thermostat assembly area. On Chrysler 300, Dodge Charger, Dodge Challenger, and Dodge Magnum applications, a worn or cracked housing can lead to coolant leaks, unstable operating temperatures, air in the cooling system, or damaged sealing surfaces. Dorman 902-035 is engineered to match the original housing form and durability requirements for these vehicles.

• Coolant seepage at the housing or seal surface
• Cracked or heat-damaged plastic housing
• Air trapped in the cooling system
• Improper coolant flow caused by a failing housing
• Fitment issues when replacing the original thermostat housing

Installation Notes

Verify the outlet port diameter, 45-degree neck angle, and mounting hole layout before installation. Transfer only the components required by the application, and inspect the mating surface, hose connection, and gasket area for debris or damage. Bleed the cooling system after service to remove trapped air and confirm proper coolant circulation.

Quality Assurance

Dorman designs this replacement thermostat housing to match the fit and durability of the stock part on specified vehicles and to withstand extreme temperature changes for extended service life.
