Help keep your electric cooling fan switching on when the engine needs it with the Four Seasons Engine Cooling Fan Switch, part number 35935, an engine-mounted temperature switch that senses engine temperature and controls the cooling fan circuit. It fits many vehicles, among them the 1984-1994 Ford Tempo, 1984-1994 Mercury Topaz and 1985-1989 Mercury XR4Ti, as a direct-fit replacement for the listed applications.
- Vehicle-specific design: made for specific vehicle applications.
- Brass construction: brass is used for accurate temperature sensing.
- Zinc-coated terminal: the terminal has a zinc coating to resist corrosion.
- Sealing parts included: comes with the gaskets, O-rings or seals needed to replace the switch properly.
The switch mounts on the engine and responds to engine temperature. At its set point it completes or opens the fan control circuit, so the electric fan runs when the radiator needs more airflow.
Signs this switch may need replacing include a cooling fan that never comes on, a fan that runs all the time, a temperature gauge that climbs in slow traffic, or a leak at the switch. Other faults can cause the same symptoms, so diagnose the cause before you replace the switch. If a failed switch is the problem, this switch replaces it.
Four Seasons draws on more than 50 years of mobile A/C experience and engineers and tests its products for dependable service. See the Buyer's Guide tab for the full vehicle list.
