# Stant 27282 Thermostat Seal for GMC C & K Series Pickup (C/K pickups), 1974, 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 C & K Series Pickup (C/K pickups). It isn't a wall of every car ever made, just yours.

## Model this seal fits

- GMC C & K Series Pickup (C/K pickups) (1974, 1992–1994)
- 6-Cyl. 250 cu in: 1974
- 6-Cyl. 292 cu in: 1974
- V-6 4.3L: 1993–1994
- V-8 350 cu in: 1974
- V-8 454 cu in: 1974
- V-8 5.0L: 1992–1994
- V-8 5.7L: 1992–1994

Stant's catalog also lists the Stant 27153 thermostat gasket (1974) for this same engine and years. Check your old parts to see whether your housing takes the seal, the gasket, or both.

## 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

Back in 1997, when almost nobody had a website, Don and Kathy were already selling car parts online. They were the very first web customer of Daniel Comp's Intelligent Network. They've since sold through eBay, Bonanza, and their own site, and kept the sales coming no matter how often the internet changed its rules.

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.
