Keep the cooling fan cycling on cue with the Four Seasons Engine Cooling Fan Switch, MPN 36504. This radiator-mounted temperature switch monitors engine coolant temperature and signals the cooling fan circuit, closing the contacts as coolant heats up and opening them as it cools. It's a direct-fit replacement for the 1991-1992 Nissan NX, 1988-1990 Nissan Pulsar NX, 1986-1988 Nissan Sentra, and 1986-1988 Nissan Tsuru (all engines).

  • Brass construction for accurate temperature sensing.
  • Zinc-coated terminal to resist corrosion.
  • Includes gaskets, o-rings, or seals to properly complete the replacement.
  • Switch specs: normally open, contacts close at 203°F (on) and open at 185°F (off); M16 x 1.50 male fitting; 2-pin rectangular female connector; radiator mount.

Meets or exceeds OEM specifications. If a failed radiator fan switch is the cause of an overheating fan that won't engage, this replaces it — diagnose the cause before replacing. Quantity per application is 1.
