Detailed Description

This Dorman thermostat housing, part number 902-3017, is designed for vehicles that use a 90-degree coolant outlet and a two-bolt mounting pattern. It cross-references Carlson 7041 and Motorad CH4017 for the same application. The housing is built to replace worn, cracked, or heat-damaged original parts in the cooling system on Dodge Caravan, Plymouth Voyager, Dodge Grand Caravan, Plymouth Grand Voyager, and Chrysler Voyager models listed in the fitment data.

Because the housing is metal rather than plastic, it is suited for service environments where repeated heat cycling can stress the original component. The included gasket supports a proper seal at the housing-to-engine interface.

Common Problems This Part Can Address

• Coolant leakage at the thermostat housing
• Cracked or warped original housing
• Corrosion or heat damage around the coolant outlet
• Improper sealing at the thermostat housing flange
• Cooling-system service on a worn OE housing

Installation Notes and Tips

Verify the outlet port diameter, 90-degree neck angle, and two-hole mounting pattern before installation. Clean the mating surface thoroughly and inspect the thermostat, since this housing does not include one. Replace the gasket during service and torque fasteners evenly to help maintain a secure seal. Confirm vehicle application by year and model before ordering; this part fits 2000 Chrysler Voyager, 1996-2000 Dodge Caravan, 1996-2000 Plymouth Voyager, 1996-1997 Dodge Grand Caravan, and 1996-1997 Plymouth Grand Voyager.

Quality Assurance

Dorman designs replacement cooling-system components to match OE fit and service requirements for specified applications. Part number 902-3017 is engineered for the listed Chrysler and Dodge vehicles and built to withstand extreme temperature changes for extended service life.
