# Stant 27273 Thermostat Seal for Oldsmobile Bravada, 1992–1994

Oldsmobile was General Motors' comfortable middle-class car, and for many years it was America's oldest car brand. On the Oldsmobile side, Stant's catalog lists the 27273 for 11 models from 1986 to 1994.

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

## Model this seal fits

- Oldsmobile Bravada (1992–1994)
- V-6 4.3L: 1992–1994 — catalog note: 1992: engine VIN code W

## Help choosing the right seal

The 27273 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 33609, is described as a grooved, molded seal, about 1.56 in. inside diameter × 1.636 in. outside diameter × 0.27 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

Don was born in 1936 and grew up on a Saskatchewan farm, four miles from a town of about 150 people. As a young man he drove trucks through deep snow in Canada's Northwest Territories, hauling dynamite to seismic crews. Kathy grew up in South Dakota, blizzards and all. Together they've spent close to three decades helping people keep old cars on the road.

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.
