# Stant 27269 Thermostat Seal for Audi 90, 1988

Audi is the German maker that made its name in the 1980s with five-cylinder engines and quattro all-wheel drive, and its older cars reward owners who keep them right. On the Audi side, Stant's catalog lists the 27269 for 6 models from 1971 to 1990.

This page is for one model only: the Audi 90. It isn't a wall of every car ever made, just yours.

## Model this seal fits

- Audi 90 (1988)
- 4-Cyl. 2.0L: 1988

## Help choosing the right seal

The 27269 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 33607, is described as a O-ring seal, about 1.93 in. inside diameter × 2.25 in. outside diameter × 0.158 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.
