Detailed Description

This Motorad thermostat housing assembly is engineered for direct replacement service on vehicles such as the Dodge Grand Caravan, Chrysler Town & Country, Ram ProMaster, and Volkswagen Routan. The 908-203 is specified at 203°F and is built to maintain stable coolant flow and operating temperature in demanding automotive cooling systems. This part cross-references Dorman OE Solutions 902-3036 for the same application.

As part of Motorad’s Integrated Housing Thermostat line, this assembly is manufactured to OE specifications with materials selected for consistent sealing and temperature response. The integrated design reduces the need to source separate thermostat and housing components when servicing the cooling system.

Common Cooling System Issues It Can Address

• Engine running hotter than normal due to thermostat wear
• Coolant leaks at the thermostat housing or seal surface
• Delayed warm-up from a thermostat that no longer opens at the correct temperature
• Air trapped in the cooling system after service
• Temperature fluctuation caused by a worn thermostat assembly

Installation Notes and Tips

Verify the 203°F temperature specification and match the vehicle application before installation. Inspect the mating surfaces, replace any damaged coolant hoses or clamps, and follow the vehicle service procedure for coolant refill and air bleeding. The bleeder hole and jiggle pin help with air relief during service, but the cooling system should still be properly purged after installation.
