Thermostats & Housings

This page covers the parts that control coolant and fluid temperature: engine thermostats, thermostat housings and water necks, housing gaskets, and thermostatic controls for remote oil coolers. Crown Automotive, SCE Gaskets, Derale, PRW, Edelbrock and Vibrant Performance make the range.

Crown Automotive makes replacement thermostats and housings for Jeep vehicles, and the Jeep lineup is well covered here: the Jeep CJ5 and Jeep CJ6, the Jeep Wrangler, Jeep Cherokee, Jeep Grand Cherokee and Jeep Wagoneer. For Chevrolet engines, Edelbrock offers polished aluminum water necks for Chevrolet V6 and V8 engines and a high-performance thermostat. PRW water neck outlets come in polished, chrome and black finishes, and SCE Gaskets supplies housing gaskets for small-block and big-block Chevrolet and Pontiac V8 engines, including bulk packs for shops.

Derale fluid control thermostat kits do a different job. They sit in the line to a remote oil cooler and send fluid through the cooler only once it is warm, or switch an electric cooler fan on at a set point such as 180°F. They are sold by fitting size, for example 3/8-inch NPT, 1/2-inch NPT or -6AN, so match the fitting to your lines. Vibrant Performance offers a thermostat for an oil cooler sandwich adapter, which does the same for engine oil.

The opening temperature matters. The Edelbrock 160-degree thermostat opens earlier than most factory units, which suits an engine built or tuned around it; a stock engine should keep its original rating. Other vehicles covered include the Chevrolet Corvette, Chevrolet Camaro, Pontiac Firebird and Dodge Charger, and each product page lists the years, makes and models it fits.
