Fan Temperature Switch, 3/8" Pipe Thread Electric Engine Cooling Fan Thermostat Temp Sensor Switch for Automotive Cooling System (180-165℉)

Feature:【Temperature Control】This switch automatically activates your cooling fan at specific temperature and shuts it off at specific temperature, maintaining optimal operating temperature to prevent overheating. Compatible for 265 283 305 307 327 350 383 400 396 402 427 454 472 502 260 289 302 351W 347 352 360 390 406 427 428 429 460 351C 351M 400M 273 318 340 360 361 383 400 413 426W 440 455 330 326 engines.【Universal 3/8" Pipe Thread 】Featuring standard 3/8" thread, this switch fits most engine blocks, intake manifolds, or radiator ports. It works seamlessly with 10"–16" single/dual electric fan (including popular aftermarket setups), making it a versatile upgrade for cars, trucks, RVs, or custom builds.【Durable and Strong】Crafted from high-strength, rustproof metal, the switch resists vibration, and extreme under-hood temperatures. The threaded probe and housing ensure long-term durability—no cracking or loosening even in harsh driving environments.【Easy to Install】Designed with a single spade terminal, this switch simplifies wiring: just connect to your fan relay''s ground circuit (no complex programming needed). The compact, low-profile design fits tight spaces, adds installation flexibility.【Engine Safety】By eliminating manual fan control, this switch reduces unnecessary power draw (saves battery life) while ensuring fans run *only when needed*. It directly replaces OEM switches, extending engine lifespan, improving fuel efficiency, and preventing costly overheating damage.Specification:Name: Fan Temperature Switch Material: MetalModel: 180-165℉Package Included:1 * Fan Temperature Switch
