Control when your cooling fan switches on and off with this Four Seasons switch, the Four Seasons Engine Cooling Fan Switch (MPN 36504), a radiator-mounted cooling fan temperature switch that serves as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1986-1988 Nissan Sentra, 1991-1992 Nissan NX and 1988-1990 Nissan Pulsar NX; see the Buyer's Guide tab for the full list. Threaded into the radiator, it senses coolant temperature and signals the cooling fan circuit, closing to energize the fan as the coolant heats up and opening again as it cools.
Calibrated switching: rated to turn on at 203° and off at 185°, with a normally-open contact design.
Brass construction for accurate temperature sensing.
Zinc-coated terminal to resist corrosion.
M16 x 1.50 male fitting thread with a 2-pin rectangular female connector; includes gaskets, o-rings or seals needed to properly replace the product.
Four Seasons rates it as meeting or exceeding OEM specifications. If a failed fan temperature switch is the cause of a fan that won't cycle correctly, this replaces it — diagnose the circuit first. This switch is sold as one unit; each listed application uses one.
Is this the right NX switch for a 1991-1992 Nissan NX?
