Help your electric cooling fan come on when the engine calls for it with the Four Seasons Engine Cooling Fan Switch, part number 36531, an engine/radiator-mounted cooling fan temperature switch. It fits many vehicles, among them the 1986-1994 Honda Accord, 1985-1996 Honda Prelude and 1996-1998 Acura TL. See the "Vehicles it fits" section for the full list and engine details.
The switch senses coolant temperature and is designed to signal the cooling fan to turn on once the engine reaches its switching temperature. The fan then moves air through the radiator.
- Brass construction: built from brass for accurate temperature sensing.
- Zinc-coated terminal: the terminal carries a zinc coating to help resist corrosion.
- Sealing parts included: contains the gaskets, O-rings or seals needed to properly replace the switch.
- Vehicle-specific design: made for specific vehicle applications.
Four Seasons engineers and tests its products with long, trouble-free service in mind. The brand draws on more than 50 years of mobile A/C experience.
These signs may mean the fan switch needs replacing:
- a cooling fan that never switches on
- a temperature gauge that climbs at idle or in stop-and-go traffic
- a fan that runs all the time
Relays, wiring and the fan motor can cause similar symptoms, so diagnose the cause first. If a failed switch is the cause, the 36531 replaces it.
