Stant 27152 Thermostat Gasket for American Motors American (1965)
1965
Don's own Stant 27152, still on its BB 52 card. Click the photo for a closer look.
American Motors was born in 1954 when Nash and Hudson joined forces. Its cars sold on sensible size and good engineering when Detroit was building bigger every year, and they still have a loyal following today. On the American Motors side, the interchange listings tie this gasket to 3 models from 1965 to 1965.

Help choosing the right gasket
The 27152 is a Stant thermostat gasket on a BB 52 card: a black gasket with a large round center opening, three bolt holes and a small square tab. Stant's 271xx gaskets are the single packs of its 251xx numbers, and the BB 52 on this card matches Stant's B52 code. Motorad's catalog names Stant 27152 directly as an interchange for its MG52 gasket, and Gates, Fel-Pro and Motorad all tie the same gasket to Stant 25152 and B52. The vehicle list here comes from those interchange listings, not from a Stant catalog, so treat it as a strong lead, not a guarantee.
Before you order, match three things: your year, your model, and your engine. Measure before you order: the catalogs list a hole of about 1.63 to 1.64 inches and three bolt holes. Set your thermostat housing (or your old gasket) on the photo and make sure the opening and bolt holes line up. If you're not sure, just ask Don and Kathy. They'll help you sort it out.
