Help your engine's electric cooling fan switch on when the coolant calls for it with the Four Seasons switch, part number 36479. It is a radiator-mounted cooling fan temperature switch (engine cooling fan switch) with brass construction for accurate temperature sensing. It fits many vehicles, among them the 1985 Mercedes-Benz 380SL, 1989 Mercedes-Benz 560SL and 1979-1987 Volvo 244, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
This temperature switch mounts in the radiator. It senses coolant temperature and helps control when the electric cooling fan runs. If a failed fan switch is why your fan won't engage or won't shut off, this unit replaces it.
Four Seasons engineers and tests its products, drawing on more than 50 years of mobile A/C experience.
Signs this switch may need replacing include a cooling fan that does not come on, a fan that runs constantly, engine temperature rising at idle or in traffic, and coolant seepage around the switch.
