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 27285 (single pack); same seal as Stant 25285 in the Stant catalog - Type: Engine coolant thermostat / water outlet seal (rubber) - Cross-references: Stant equivalents 25285 Stant's own 1928–1994 application catalog lists the 27285 for 2 makes from 1992 to 1994. It's a good fit for restoration projects, weekend drivers and mechanics keeping older vehicles running. **Compatible Makes & Models (from the Stant catalog)** - **Ford** (1993–1994): Probe (1993–1994) - **Mazda** (1992–1994): 626 (1993–1994), MX-3 (1992–1994), MX-6 (1993–1994) **Note**: Always verify fitment for your specific year, make, model and engine. 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. Heads-up: current retailer listings (PartsHawk) show 27285 as the replacement for the older 27270 (Saab/Volvo) and 27278 (Cadillac/Volvo) seals. Those later cross-overs are retailer data only, so this page lists only the Ford/Mazda applications that the 1928–1994 Stant catalog gives for 27285. If you have a Saab, Volvo or Cadillac, see our 27270 and 27278 pages or 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 27285 Thermostat Seal: The Right Seal for Ford and Mazda 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 27285 across 2 makes (Ford, Mazda). Cross-reference tables tie it to the Stant 25285, which makes it easy to match against an old parts list or a worn-out seal. **Real-World Fitment Examples** - 1993–1994 Ford Probe 4-Cyl. 2.0L - 1993–1994 Mazda 626 4-Cyl. 2.0L **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. - 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 27285 Source: Stant *Thermostats, Gaskets, Caps – 1928 through 1994* (application pages).
