Metco Motorsports MTO0003 Billet Thermostat Housing Buick Turbo

The Metco Motorsports billet thermostat housing for the Buick Grand National is CNC-machined for precision fit and maximum durability. It installs as a direct replacement for the rusted or collapsed OEM housing and includes a new high-quality O-ring. Our thermostat housing for the turbo Regal application is unique in that the inside contours of the housing around the thermostat promote coolant flow and reduce cavitation in the coolant.

Also included in this kit is our replacement thermostat housing clamp. Our clamp is precision machined from billet aluminum and is the perfect complement to our billet thermostat housing. A stainless-steel socket head screw and lock washer are included to complete your installation.
