Keep an accurate read on engine coolant temperature with the Four Seasons switch, part number 36401, an engine coolant temperature sensor / switch with brass construction for accurate temperature sensing. It fits many vehicles, among them the 1981-1984 Chevrolet Impala, 1981-1982 Chevrolet Malibu and 1981 Chevrolet Camaro, and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Four Seasons catalogs this part as a coolant temp sensor switch, so it is listed under both names. The sensor responds to the temperature of the engine coolant and sends that signal to the vehicle's temperature gauge, warning light or other related circuit, depending on the application.
- Brass construction: chosen for accurate temperature sensing.
- Zinc-coated terminal: helps resist corrosion.
- Color coded: for easy identification.
- Sealing parts in the box: comes with the gasket, O-ring or seal needed to replace the unit properly.
Signs this part may need replacing include a temperature gauge that reads erratically or stays at one end of its scale, or coolant seeping around the sensor. Wiring faults or a failing gauge can cause the same symptoms, so confirm the cause before replacing. Four Seasons draws on more than 50 years of mobile A/C experience.
