Good To Know

Q: Does this housing come with a thermostat or gasket? A: The listing covers the aluminum housing itself, so check whether your thermostat and gasket are reusable or order them separately to complete the job.

Q: Will an aluminum housing seal properly on my stock Mustang? A: Yes, it is machined to match the factory mounting surface, but always clean the mating area and torque bolts to spec to prevent leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
