# Stant 27282 Thermostat Seal for GMC Suburban, 1992–1994

GMC trucks were the professional-grade cousins of Chevrolet trucks, built side by side and often sharing the same engines and cooling parts. On the GMC side, Stant's catalog lists the 27282 for 9 models from 1974 to 1994.

This page is for one model only: the GMC Suburban. It isn't a wall of every car ever made, just yours.

## Model this seal fits

- GMC Suburban (1992–1994)
- V-8 5.7L: 1992–1994

## Help choosing the right seal

The 27282 is a Stant thermostat seal, a molded rubber ring that seals the thermostat or the water outlet (thermostat housing) instead of a flat paper gasket. Its Gates equivalent, Gates 33619, is described as a grooved seal, about 1.95 in. inside diameter × 2.31 in. outside diameter × 0.15 in. thick. Stant's own description of these seals: no sealer or RTV is needed for a leak-proof seal, and each one is shaped for its application. Stant made a different seal for each housing design, and Don stocks several of them, so check which number your car calls for.

Before you order, match three things: your year, your model, and your engine. Catalogs list fitment by vehicle, but some engines had more than one thermostat housing design over the years. If your old seal is still in hand, compare its size and shape, or just ask Don and Kathy. They'll help you sort it out.

## Real people behind the parts

In their early web days, Don and Kathy built separate "garages" online, one for Mustangs, one for Chevettes, and one for Corvettes, so that every owner could find their own corner. These pages carry on that idea: every model gets its own page.

These seals come from Don's own shelves.

## Price is $9.95 plus $3.00 for shipping.

Don and Kathy offer a fair deal for this. Buying for a club, a shop, or a whole fleet of project cars? Even better.
