# Stant 27281 Thermostat Seal – Fitment Guide for Asuna, Daihatsu, Ford, Geo, Mazda, Pontiac and more (1976–1994)

**Stant 27281 Engine Coolant Thermostat Seal – from Don's Obsolete Auto Parts**

Keep your car or truck on the road with a genuine Stant 27281, the Stant thermostat seal for Toyota 2.4L and 3.0L trucks (Pickup, 4Runner, T100), Supra, Cressida, Celica and Corolla engines, the 1989–1994 Ford Taurus 3.0L (Eng. VIN Y) and 3.2L SHO, the Mazda RX-7 rotary, Daihatsu Charade and Rocky, Suzuki Sidekick / Geo Tracker and the Renault Alliance and Encore. 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 27281 (single pack); same seal as Stant 25281 in the Stant catalog  
- Type: Engine coolant thermostat / water outlet seal (rubber, grooved style per the Gates equivalent)  
- Size: about 1.9 in. inside diameter × 2.15 in. outside diameter × 0.26 in. thick (Gates 33618 data for the direct equivalent)  
- Cross-references: Gates 33618; Carquest 30745; Daihatsu 1634187103000; Dayco 82514; Ford E9DZ 8590 A, E9OZ 8255 A, E9OZ 8590 A; General Motors 91171052, 91174501; Ideal Tridon 30988; NAPA 1086  

Stant's own 1928–1994 application catalog lists the 27281 for 9 makes from 1976 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)**  
- **Asuna** (1993–1993): Sunrunner (1993)  
- **Daihatsu** (1989–1992): Charade (1989–1992), Rocky (1990)  
- **Ford** (1989–1994): Taurus (1989–1994)  
- **Geo** (1993–1993): Tracker (1993)  
- **Mazda** (1989–1994): RX-7 (1989–1991, 1993–1994)  
- **Pontiac** (1994–1994): Sunrunner (1994)  
- **Renault** (1985–1987): Alliance (1985–1987), Encore (1985–1986)  
- **Suzuki** (1992–1994): Sidekick (1992–1994)  
- **Toyota** (1976–1994): 4Runner (1984–1994), Celica (1983–1985), Corolla (1976–1982, 1984–1985), Cressida (1983, 1989–1992), Pickup (1983–1994), Supra (1986–1992), T100 (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.

**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 27281 Thermostat Seal: The Right Seal for Asuna and Daihatsu 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 27281 across 9 makes (Asuna, Daihatsu, Ford, Geo, Mazda, Pontiac, Renault, Suzuki, Toyota). Cross-reference tables tie it to the Stant 25281 and Gates 33618, which makes it easy to match against an old parts list or a worn-out seal.

**Real-World Fitment Examples**  
- 1993 Asuna Sunrunner 4-Cyl. 1.6L (Canada)  
- 1990–1992 Daihatsu Charade 4-Cyl. 1.3L  
- 1992–1994 Ford Taurus V-6 3.0L  
- 1993 Geo Tracker 4-Cyl. 1.6L  
- 1993–1994 Mazda RX-7 2-Rotor 1.3L  
- 1994 Pontiac Sunrunner 4-Cyl. 1.6L (Canada)  
- 1985–1987 Renault Alliance 4-Cyl. 1.7L  
- 1992–1994 Suzuki Sidekick 4-Cyl. 1.6L  

**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 27281 is about 1.9 in. inside diameter × 2.15 in. outside diameter × 0.26 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.
