A thermostat seal is a molded rubber ring that seals the thermostat or the water outlet instead of a flat paper gasket. Stant's description of these seals: no sealer or RTV is needed, and each one is shaped for its application. **Key Features** - Part Number: Stant 27271 (single pack); same seal as Stant 25271 in the Stant catalog - Type: Engine coolant thermostat / water outlet seal (rubber, O-ring style per the Gates equivalent) - Size: about 2.359 in. inside diameter × 2.637 in. outside diameter × 0.14 in. thick (Gates 33613 data for the direct equivalent) - Cross-references: Gates 33613; BMW 11511714519, 11531265084, 11531304202; British Leyland EAC8999; Carquest 30929; Carter 26-5071; Chrysler 550580; Dayco 82504, 82507; Edelmann 6029 Stant's own 1928–1994 application catalog lists the 27271 for 13 makes from 1959 to 1994.

Some catalog lines are limited to one engine code or housing type; the full engine-by-engine list is in the fitment appendix below. If you have your old seal, compare its size and shape, or just ask Don and Kathy. **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. **Why Buy From Don & Kathy at Don's Obsolete Auto Parts?** Don Leask founded one of the earliest online obsolete auto parts businesses (carparts2 on eBay in 1997, the second auto parts store on eBay) and grew it to 11,000–17,000 unique listings. Today, with help from their digital agent Misty (misty@donsobsoleteautoparts.com), Don and Kathy connect directly with restorers and collectors while preserving their legacy of quality parts. These seals come from Don's own shelves. To reach them, click the "Don & Kathy Leask" button at the bottom left of any page on donsobsoleteautoparts.com, or email misty@donsobsoleteautoparts.com. **The Stant 27271 Thermostat Seal: The Right Seal for Audi and BMW Owners** Thermostat seals are small, but they decide whether a cooling system stays dry. When the thermostat housing comes off, the right seal is the quiet part that keeps the job from turning into a second trip to the parts counter. **Why This Seal Matters** Stant's application catalog covering 1928 through 1994 lists the 27271 across 13 makes (Audi, BMW, Dodge, Eagle, Jaguar, Jeep, Lincoln, Mercedes-Benz, Peugeot, Porsche, Renault, Volkswagen, Volvo). Cross-reference tables tie it to the Stant 25271 and Gates 33613, which makes it easy to match against an old parts list or a worn-out seal. **Real-World Fitment Examples** - 1989–1991 Audi 100 5-Cyl. 2.3L - 1971 BMW 2500 6-Cyl. 152 cu in - 1990–1992 Dodge Monaco V-6 3.0L - 1988–1992 Eagle Premier V-6 3.0L - 1988–1989 Jaguar XJ6 6-Cyl. 3.6L - 1985–1987 Jeep Cherokee 4-Cyl. 2.1L Diesel - 1984–1985 Lincoln Continental 6-Cyl. 2.4L Diesel - 1959 Mercedes-Benz 190 4-Cyl. 116 cu in Diesel **Keeping Older Cars on the Road** Don and Kathy Leask have been part of the classic car world since the early days of the internet. Starting with carparts2 on eBay in 1997, they became one of the largest online sellers of obsolete parts. Now, with their Don's Obsolete Auto Parts site and digital agent Misty, they're making hard-to-find parts discoverable again, connecting owners of rare inventory with the enthusiasts who need them. **Buying Tips** - Match three things before ordering: year, model and engine. Watch for catalog notes such as engine VIN codes or housing type. - Compare sizes: the 27271 is about 2.359 in. inside diameter × 2.637 in. outside diameter × 0.14 in. thick. - Some engines use a gasket and a seal at the thermostat; check what came off yours. - Restoration shops, clubs and collectors can ask about quantity pricing. --- ## Fitment appendix — every Stant catalog line for 27271 Source: Stant *Thermostats, Gaskets, Caps – 1928 through 1994* (application pages).
