Mounted in the radiator, this Four Seasons switch (part number 36484) senses coolant temperature and signals the engine cooling fan to turn on and off as the engine warms and cools. It fits many vehicles, among them the 1997-1998 BMW 740i, 1997-2000 BMW 528 Series and 1997-2000 BMW 528i. See the Buyer's Guide tab for the full list and engine details.
Four Seasons lists this part as both an engine cooling fan switch and a radiator-mounted cooling fan temperature switch. It is a direct-fit replacement for the listed applications.
- Vehicle-specific: built for specific vehicle applications, not as a one-size-fits-all switch.
- Sealing parts included: comes with the gaskets, o-rings, or seals needed to replace the switch properly.
- Brass construction: chosen for accurate temperature sensing.
- Zinc-coated terminal: the zinc coating helps the terminal resist corrosion.
Four Seasons designs and tests its products with the aim of years of trouble-free operation. The company draws on more than 50 years of experience in mobile A/C.
Signs this part may need replacing include a cooling fan that does not come on, an engine running hotter than normal, or a fan that runs when it should not. Other cooling-system faults can cause the same symptoms, so diagnose the cause before replacing the switch. If a failed fan switch is the problem, this part replaces it.
