# Stant 27101 Thermostat Gasket for Rover 3500, 1980

Rover was the British maker of solid, well-engineered saloons, and its P5 and P6 cars still have a devoted following. On the Rover side, the catalogs list the Stant 27101 for 4 models from 1960 to 1980.

This page is for one model only: the Rover 3500. It isn't a wall of every car ever made, just yours.

## Model this gasket fits

- Rover 3500 (1980)
- Engines listed in the catalog: 8 Cyl 3.5L

## Help choosing the right gasket

The 27101 is a universal 14-hole thermostat gasket from Stant, the kind a mechanic reaches for when the original cut gasket for an older or less common housing is hard to find. The catalogs list its hole diameter at 1.63 inches. Lay your thermostat housing on it, check that the opening and bolt holes line up with your engine's outlet, and trim to fit if needed. 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.
