# Stant 27147 Thermostat Gasket for Mercury Voyager, 1957

[![Stant 27147 thermostat gasket](/i/media/stant-27147-thermostat-gasket.jpg)](/i/stant-27147-thermostat-gasket.html)

*Don's own Stant 27147, still on its BB 47 card. Click the photo for a closer look.*

Mercury sat between Ford and Lincoln, with a little more style and a little more comfort than a Ford, often with the same engines underneath. On the Mercury side, the interchange listings tie this gasket to 9 models from 1954 to 1962.

## What it fits

- Mercury Voyager (1957)
- Engine: not given in the listing

## Help choosing the right gasket

The 27147 is a Stant thermostat gasket on a BB 47 card: a white, nearly square gasket with four bolt holes and a large round center opening, packed with a second, smaller oval gasket that has a center hole and two bolt holes. Stant's 271xx gaskets are the single packs of its 251xx numbers (Stant's own catalog pairs, for example, 25148 with 27148 "1 Pack"), and the BB 47 on this card matches Stant's B47 code. The vehicle list here comes from the Gates 33630 catalog listing, which names Stant 25147 and B47 as its interchange. Neither Stant's printed catalogs nor any seller we found list the 27147 itself, so treat the list as a lead, not a guarantee.

Before you order, match three things: your year, your model, and your engine. Measure before you order: Gates lists a 2.22 inch hole for this gasket, and Motorad lists 2.20 inches inside and 2.95 inches outside for its version. 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.

## Real people behind the parts

Don and Kathy Leask have been selling obsolete and restoration auto parts online since 1997. Their eBay store, carparts2, was the second auto parts store on eBay.

These gaskets come from Don's own shelves, in original Stant packaging.

## Price is $9.95 plus $3.00 for 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.

At present I have a total of 9 of these Stant thermostat gaskets number 27147 if you want more even some with different numbers let's talk.
