TH-302 / TH-351W — Thermostat Housing Kit

Part No. TH-302 | Part No. TH-351W

Limited Supply — While Castings Last

PME offers the TH-302 and TH-351W for cast iron heads or aluminum heads, and you can have it with or without the water bypass. Cruiser or racer, we’ve got you covered.

The housing is powder coated (aluminum color) for looks and easy maintenance. Kit is sold complete with fittings and hoses — everything you need for installation is in the box.

The thermostat housing mounts to the engine by removing the top two bolts on the 351W front cover and replacing them with the studs included in the kit.

The part has been machined to accept the 90-degree neck of the 429–460 Ford, the angled neck of the Modified, and the straight-up neck of a 351C.

Clevor Engine Owners — You’re in Luck!

Owners of 351W blocks or 302 blocks with 351C heads have a special place at PME. We like the idea of the big canted valve head — but at PME we like the water to go out front where it belongs.

Note: This product cannot be used on water pumps made before 1970. On earlier models the bypass water hose connection is different and would have to be supplied by the consumer.
