Detailed Description

This engine coolant thermostat housing assembly is engineered as a direct-fit replacement for the stock housing on specified Chrysler and Ram vehicles. The housing is made from plastic and uses a gasket seal design to help restore proper coolant routing and thermostat control. With a 0.626 inside diameter, 4.208 flange length, 3.623 flange width, and 0.407 flange thickness, the assembly is built around the original mounting layout for service replacement work. The thermostat opens at 194 degrees F, and the package includes the thermostat, sensor, and gasket needed for the repair.

What It Helps Fix

• Coolant leaks from a cracked or worn thermostat housing

• Warning lights or drivability concerns related to the coolant sensor area
• Improper coolant flow through the thermostat housing assembly
• Service problems caused by damaged sealing surfaces or gasket failure

Installation Notes

Verify vehicle application before installation. This assembly uses three mounting holes and a gasket seal, and mounting hardware is not included.

For fitment-specific service, confirm the vehicle is one of the listed Chrysler Pacifica, Voyager, Grand Caravan, or Ram ProMaster models for the correct year range.
