Stant 27148 Thermostat Gasket for Pontiac LeMans (1976–1977, 1979, 1981)
1979, 1981
Don's very first car was a 1936 Pontiac convertible, bought by his father for about $600 when Don was in high school in Saskatchewan. So Pontiac has a special place in this shop. On the Pontiac side, the catalogs list the Stant 27148 for 12 models from 1975 to 1989.
This page is for one model only: the Pontiac LeMans. It isn't a wall of every car ever made, just yours.

Help choosing the right gasket
The 27148 is a Stant Stat Lok thermostat gasket. The catalogs list its hole diameter at 1.69 inches, which is a handy check against the old gasket in your hand. "Stat Lok" means it has an adhesive backing that holds the thermostat centered in its seat while you bolt the housing down, so there's no gasket cement, no thermostat falling out, and less risk of cracking the outlet flange. Stant cut a different gasket for each housing design, and Don stocks several of them, so check which number your car calls for.
Before you order, match three things: your year, your model, and your engine. Catalogs list fitment by vehicle, but some engines had more than one thermostat housing design over the years. If your old gasket is still in hand, compare its shape and bolt holes, or just ask Don and Kathy. They'll help you sort it out.
Real people behind the parts
Back in 1997, when almost nobody had a website, Don and Kathy were already selling car parts online. They were the very first web customer of Daniel Comp's Intelligent Network. They've since sold through eBay, Bonanza, and their own site, and kept the sales coming no matter how often the internet changed its rules.
These gaskets come from Don's own shelves, in original Stant packaging.
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.
