# Stant 27140 Thermostat Gasket (Stat Lok, NOS) – Fitment Guide for AM General, American Motors, Buick, Chevrolet, Chrysler, DeSoto and more (1933–1994)

**Stant 27140 Stat Lok Engine Coolant Thermostat Gasket – NOS in Original Stant Packaging**

Keep your classic on the road with a genuine Stant 27140, the Stant thermostat gasket for Chrysler-family V8s (and some early sixes) from the 1940s through 1978, Ford/Edsel/Lincoln/Mercury big-block V8s from 1958 to 1967, Pontiac from 1933 to 1967, GM's 6.2L and 6.5L diesel V8s from 1982 to 1994, and 1958–1966 Rambler/AMC (two required on those). Stant's Stat Lok gaskets have an adhesive backing that holds the thermostat centered in its seat while you bolt the housing down — no gasket cement, no thermostat falling out, and less risk of misalignment or cracking the outlet flange.

**Key Features**  
- Part Number: Stant 27140 (single pack); same gasket as Stant 25140 in the Stant catalog and cross-reference tables  
- Type: Engine coolant thermostat (housing/water outlet) gasket, Stat Lok adhesive-backed  
- Thermostat opening (mounting hole) diameter: 2.25 in. (per Gates/retailer data for the direct equivalent)  
- Condition: New Old Stock (NOS) in original Stant packaging  
- Cross-references: Gates 33625; AMC OE 41217, 3128233, 3171856; Chrysler OE 2959151; Fel-Pro 11430, 11805, 4880, 35153, 35004, 35063; GM OE 22532588, 3830016, 12551507, 12551591, 14028916, 14057196; OE E9TZ8255B, C8PZ8255AA, B8E8255A, EDC8255A, C1VE8255A, EDF8255A, C8PZ8255U, B8A8255A and more  
- Note: some Rambler/AMC applications use **two** of these gaskets (marked below)  

Stant's own 1928–1994 application catalog lists the 27140 for 17 makes from 1933 to 1994. It is ideal for restoration projects, weekend drivers and mechanics working on obsolete iron.

**Note**: Always verify fitment for your specific year, make, model and engine. The full engine-by-engine list is in the fitment appendix below. If you have your old gasket, compare its shape, bolt holes and opening size — or just ask Don and Kathy.

**Price is $9.95 plus 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 gaskets come from Don's own shelves, in original Stant packaging.

**The Stant 27140 Thermostat Gasket: The Right Seal for AM General and American Motors Restorations**

Thermostat gaskets are small, but they decide whether a cooling system stays dry. When the thermostat housing comes off a project car or truck, the right gasket is the quiet part that keeps the job from turning into a second trip to the parts counter.

The **Stant 27140** is the Stant thermostat gasket for Chrysler-family V8s (and some early sixes) from the 1940s through 1978, Ford/Edsel/Lincoln/Mercury big-block V8s from 1958 to 1967, Pontiac from 1933 to 1967, GM's 6.2L and 6.5L diesel V8s from 1982 to 1994, and 1958–1966 Rambler/AMC (two required on those). Like the rest of Stant's Stat Lok line, it has an adhesive backing that holds the thermostat in place during installation, so it seats squarely and seals the first time.

**Why This Gasket Matters**  
Stant's application catalog covering 1928 through 1994 lists the 27140 across 17 makes (AM General, American Motors, Buick, Chevrolet, Chrysler, DeSoto, Dodge, Edsel, Ford, GMC, Hudson, Jeep, Lincoln, Mercury, Plymouth, Pontiac, Rambler). Cross-reference tables tie it to the Stant 25140, Gates 33625 and Fel-Pro 11430, which makes it easy to match against an old parts list or a worn-out gasket.

**Real-World Fitment Examples**  
- Plymouth Fury, Belvedere, Satellite, Road Runner, Barracuda, Duster and Valiant V8s  
- Dodge Coronet, Charger, Dart, Challenger, Polara and D/W pickups  
- Chrysler 300, New Yorker, Newport and Imperial (1959–1978)  
- 1958–1966 Ford Thunderbird and Galaxie; Edsel; 1958–1967 Lincoln  
- Chevrolet/GMC trucks, Suburban and Blazer/Jimmy with the 6.2L/6.5L diesel  
- 1958–1966 Rambler/AMC Ambassador, American, Classic, Marlin and Rebel (two required)  

Because these were high-volume service items, NOS stock still turns up in collections like Don Leask's — in original Stant packaging, sorted by number.

**Preserving American Automotive History**  
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 AI-assisted 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. Some engines had more than one thermostat housing design.  
- Measure the thermostat opening: the 27140 is listed at about 2.25 in.  
- Prefer original packaging for authenticity; keep the Stant label with the part.  
- Restoration shops, clubs and collectors can ask about quantity pricing.  

Whether you're chasing a concours restoration or simply keeping a classic on the road, the Stant 27140 is a period-correct, ready-to-install solution.
