This kit is available for anyone who has two cooling fans.This kit will turn the fans ON at 176 degrees, and OFF at 161 degrees, using an engine mounted sensor. Dual relays protect BOTH fans, and provide full battery voltage with top quality wiring. This also eliminates the heavy load on the vehicle's ignition switch. This unit has a highly reliable thermostat. Sensor has a 3/8" pipe thread. Product may vary from photo.
