Stant 27132 Stat Lok Engine Coolant Thermostat Gasket – NOS in Original Stant Packaging

Keep your classic on the road with a genuine Stant 27132, the Stant thermostat gasket for a long run of Buick-built engines — the 196/225/231/3.8L/4.1L V6 family and Buick V8s such as the 350, 430 and 455 — as used across Buick, Oldsmobile, Pontiac, Chevrolet, GMC and Cadillac, plus Jeep's 225 V6 and 350 V8 and the 1961–1964 Rambler 196 six with the aluminum block. 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.

The Stant 27132 Thermostat Gasket: The Right Seal for Buick and Cadillac 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 27132 is the Stant thermostat gasket for a long run of Buick-built engines — the 196/225/231/3.8L/4.1L V6 family and Buick V8s such as the 350, 430 and 455 — as used across Buick, Oldsmobile, Pontiac, Chevrolet, GMC and Cadillac, plus Jeep's 225 V6 and 350 V8 and the 1961–1964 Rambler 196 six with the aluminum block. 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 27132 across 8 makes (Buick, Cadillac, Chevrolet, GMC, Jeep, Oldsmobile, Pontiac, Rambler). Cross-reference tables tie it to the Stant 25132, Gates 33621 and Fel-Pro 13087, which makes it easy to match against an old parts list or a worn-out gasket.

Real-World Fitment Examples

• Buick Skylark, Special, LeSabre, Electra, Riviera, Century and Regal
• Oldsmobile Cutlass, Delta 88 and F85 with Buick V6 power
• Pontiac Grand Prix, Bonneville, Firebird and LeMans with the 231/3.8L V6
• Jeep CJ, DJ and Jeepster with the 225 V6; Jeep Wagoneer and J-Series with the 350 V8
• 1961–1964 Rambler American and Classic with the aluminum 196 six

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 27132 is listed at about 1.88 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 27132 is a period-correct, ready-to-install solution.
