Stant 27150 Thermostat Gasket (Stat Lok, NOS) – Fitment Guide for Bricklin, Ford, Lincoln, Mercury (1962–1994)

Fitment Guide for Bricklin, Ford, Lincoln, Mercury (1962–1994)

Stant 27150 Stat Lok Engine Coolant Thermostat Gasket – NOS in Original Stant Packaging

Keep your classic on the road with a genuine Stant 27150, the Stant thermostat gasket for Ford's small-block V8 family — 260, 289, 302, 351, 4.2L, 5.0L and 5.8L — plus the 4.9L six, across Ford, Lincoln and Mercury from 1962 through 1994. 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.

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.

The Stant 27150 Thermostat Gasket: The Right Seal for Bricklin 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 27150 is the Stant thermostat gasket for Ford's small-block V8 family — 260, 289, 302, 351, 4.2L, 5.0L and 5.8L — plus the 4.9L six, across Ford, Lincoln and Mercury from 1962 through 1994. 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 27150 across 4 makes (Bricklin, Ford, Lincoln, Mercury). Cross-reference tables tie it to the Stant 25150, Gates 33633 and Fel-Pro 35067, which makes it easy to match against an old parts list or a worn-out gasket.

Real-World Fitment Examples

• Ford Mustang 289/302/5.0L (1966–1973, 1979–1994)
• Ford F-Series, Bronco and E-Series with the 302/5.0L, 5.8L or 4.9L six
• Ford Torino, Fairlane, Galaxie, LTD and Thunderbird V8s
• Lincoln Town Car, Continental and Mark VI/VII 5.0L
• Mercury Cougar, Montego, Grand Marquis and Capri V8s

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 27150 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 27150 is a period-correct, ready-to-install solution.
