Help your engine's electric cooling fan respond to engine temperature with this Four Seasons switch, part number 36511, an engine-mounted cooling fan temperature switch with brass construction for accurate temperature sensing. It fits many vehicles, among them the 1988-1991 BMW M3, 1984-1985 BMW 318i and 1984-1994 BMW 325 Series. See the Buyer's Guide tab for the full list and engine details.
The switch mounts on the engine and senses its temperature. It switches the cooling fan circuit at its set point, which helps the fan come on when the engine needs extra cooling.
- Vehicle-specific design: built as a direct-fit replacement for the listed applications.
- Brass construction: used for accurate temperature sensing.
- Zinc-coated terminal: helps the terminal resist corrosion.
- Sealing parts supplied: comes with the gaskets, O-rings or seals needed to properly replace the switch.
Signs this switch may need replacing include a cooling fan that won't switch on, a fan that runs all the time, or engine temperature rising at idle or in slow traffic. Relays, wiring and the fan motor can cause the same symptoms, so diagnose the circuit before you replace parts. Four Seasons backs its product line with over 50 years of mobile A/C experience.
