Description

Seal the thermostat housing against coolant leaks with the Gates Engine Coolant Thermostat Housing Gasket (MPN 33631). This adhesive-backed thermostat gasket sits between the thermostat and its housing, sealing the coolant passage as the thermostat opens and closes. It drops in across a broad range of classic and full-size applications, including the 1967-1974 American Motors Ambassador, 1968-1970 AMC Javelin, 1982-1985 Buick Regal, and 1977-1990 Buick LeSabre — see the Buyer's Guide tab for the full list of 244 applications spanning L4-2.5L, V6-4.3L, and V8 engines from 4.3L through 7.5L.

Adhesive-backed design: simplifies aligning the gasket with the thermostat housing to help ensure a leak-free fitment the first time.
Self-adhesive backing: holds the thermostat in place while the water outlet is installed.
Faster installs: increases installation efficiency during the job.
Options: rubber thermostat seals are also available.

The listed applications use one gasket each (Quantity Per Application: 1). A worn or hardened thermostat gasket can weep coolant at the housing; if that gasket is the source of the leak, this replaces it. Country of origin: China. Manufacturer part number 33631.
