Hybrid Racing Replacement Coolant Switch

Hybrid Racing Replacement Coolant Switch - K Series Swaps

Running a K swap with a Hybrid Racing radiator and need a replacement coolant switch? This is the Hybrid Racing coolant switch that threads into the M14 x 1.5 port on Hybrid Racing K swap radiators or any other radiator with the same thread pitch. It activates your radiator fan at approximately 199°F and turns it off at approximately 189°F. You're not guessing when the fan should kick on or running a manual toggle switch. The fan turns on automatically when it needs to.

Activates at 199°F, Deactivates at 189°F

The switch is calibrated to close the circuit and turn on your radiator fan when coolant temps hit around 199°F (92°C). Once temps drop back down to around 189°F (87°C), the switch opens and the fan shuts off. This keeps your coolant temps in the safe range without running the fan constantly or letting temps climb too high before the fan kicks on.

Plug and Play with K Series Chassis Harness

The switch plugs directly into the factory K series chassis harness or Hybrid Racing fan relay kits. You're not repinning connectors or splicing wires to make it work. If you're running a K swap in an older chassis with the Hybrid Racing radiator and fan setup, this switch plugs right into your existing harness.

Brass Body, Pre-Installed Crush Washer

The switch has a brass body that resists corrosion and handles the vibration and heat that comes with being threaded into a radiator. A crush washer's pre-installed so you get a leak-free seal when you torque it down. You're not hunting for the right washer or dealing with leaks after installation.
