# Stant 27272 Thermostat Seal for Pontiac Firebird, 1989–1991, 1993–1994

Don's very first car was a 1936 Pontiac convertible, bought by his father for about $600 when Don was in high school in Saskatchewan. So Pontiac has a special place in this shop. On the Pontiac side, Stant's catalog lists the 27272 for 3 models from 1988 to 1994.

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

## Model this seal fits

- Pontiac Firebird (1989–1991, 1993–1994)
- V-6 2.8L: 1989
- V-6 3.1L: 1990–1991
- V-6 3.4L: 1993–1994

## Help choosing the right seal

The 27272 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 33611, is described as a grooved seal, about 1.72 in. inside diameter × 1.915 in. outside diameter × 0.13 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.
