# Stant 27153 Thermostat Gasket (Stat Lok, NOS) – Fitment Guide for Chevrolet, Ford, GMC, Mercury, Oldsmobile (1960–1992)

**Stant 27153 Stat Lok Engine Coolant Thermostat Gasket – NOS in Original Stant Packaging**

Keep your classic on the road with a genuine Stant 27153, the Stant thermostat gasket for Chevrolet and GMC trucks, vans, Suburbans and Blazer/Jimmy from 1960 to 1992 (small- and big-block V8s, the 250/292 sixes and the 4.3L V6), and for Ford and Mercury FE and 429/460 big-block V8s from 1964 to 1978. 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 27153 (single pack); same gasket as Stant 25153 / B53 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: 1.81 in. (per Gates/retailer data for the direct equivalent)  
- Condition: New Old Stock (NOS) in original Stant packaging  
- Cross-references: Gates 33637; Fel-Pro 35036, 8E35004; Ford OE C7AZ 8255 A, D1PZ 8255 A, D5TZ 8255 B; Motorcraft RG-516; Victor Reinz C25487TC, C26154, C26543, C26649; OE D5TZ8255B, D1PZ8255A, C7AZ8255A  

Stant's own 1928–1994 application catalog lists the 27153 for 5 makes from 1960 to 1992. 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.

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 27153 Thermostat Gasket: The Right Seal for Chevrolet and Ford 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 27153** is the Stant thermostat gasket for Chevrolet and GMC trucks, vans, Suburbans and Blazer/Jimmy from 1960 to 1992 (small- and big-block V8s, the 250/292 sixes and the 4.3L V6), and for Ford and Mercury FE and 429/460 big-block V8s from 1964 to 1978. 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 27153 across 5 makes (Chevrolet, Ford, GMC, Mercury, Oldsmobile). Cross-reference tables tie it to the Stant 25153, Gates 33637 and Fel-Pro 35036, which makes it easy to match against an old parts list or a worn-out gasket.

**Real-World Fitment Examples**  
- Chevrolet/GMC C & K pickups, Suburban and G-Series vans (1960s–1992)  
- Chevrolet Blazer and GMC Jimmy (full-size and compact 4.3L)  
- Chevrolet El Camino (1964–1969, 1972–1973)  
- Ford Galaxie, LTD, Fairlane, Mustang and Thunderbird with the 390/427/428 (1967–1971)  
- Mercury Marquis, Monterey, Cougar and Montego with the 429/460  
- 1991–1992 GMC Syclone/Typhoon and Oldsmobile Bravada 4.3L  

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 27153 is listed at about 1.81 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 27153 is a period-correct, ready-to-install solution.
