AC PRESS CONTROLLER.JPG

Our new A/C high pressure side controller. 

It will trigger your A/C fan or Fail Safe mode fan to cool down and lower A/C pressure.  Comes with 200 PSI sensor, 10 inch hose with fittings.  Trip your fan at pressure level you select.  Ten Leds show pressure level percent in real time!

    Auto Cool controllers

    are proudly made in America!

     

    The Auto Cool Guy supplies the Standard Brass Sensor with your controller.   

     

    However, if you purchase a Brass Plug Sensor or one of the Copper Inline Sensors,  we do not supply the Standard Brass Sensor as the default sensor with your order.  

     

    Send us an email on the size of sensor you have ordered!   We are not getting the pay pal notes?

    We get a vast amount of calls and emails from pissed off guys that purchased the brand X controller from that 

    "Racing Company."
