Installation Notes and Tips

Verify the upper housing style, outlet diameter, and 45-degree neck angle before installation. Transfer any required thermostat separately, since this housing does not include one. Inspect the mating surface, replace the O-ring or gasket as needed, and confirm the mounting hole alignment before tightening fasteners.

Quality Assurance

Dorman designs this replacement thermostat housing to match stock fit and durability on the listed vehicles. The housing is built for cooling-system temperature changes that can shorten the life of lesser-quality parts.
