C5 Coolit Wireless Plug & Play Fan Controller for your 1997-2004 C5 and C5 Zo6

Now you can control your C5 Corvette's radiator high speed right side cooling fan with the simple push of a button allowing you to control your radiator coolant temperatures. No need to pay for an expensive tune to change your fans on/off temperatures. Here is SacCityCorvette’s latest version of the Cool It v2 and v3 Remote High Speed Fan Controller. It is designed as a performance and reliability enhancer that allows you to run the fan anytime and at any speed.

After you install the Cool it v2 or v3, you will be able to turn the right-side cooling fan on in high speed fan mode using a wireless FOB making it perfect for when you are at the track and you want to cool down between runs, keep cool in traffic, and idling in parades. No need to turn on your A/C anymore to cool your engine and waste fuel and A/C wear and tear! It will even help keep your Automatic Transmission running cooler too! The Coolit also allows you to keep the fan on above 35 MPH when the computer normally turns the fans off at that speed.

We have made major improvements to our latest Coolit v2 or v3 including running it on its own circuit and heavy-duty internal relays. The Coolit v2 and v3 WILL NOT interfere with the normal computer-controlled operation of your cooling fans!

A safety feature is built in that allows your computer to still turn the fans on, even if the Coolit v2 or v3 should ever fail.

The Coolit v2 or v3 uses your C5’s factory wiring to run the Right side fan in high-speed mode. Our Coolit v2 or v3 uses the highest quality parts including a factory relay not an aftermarket or copy. All connections are soldered for high quality reliability.

A simple 5-minute plug-and-play installation will immediately take your C5 Corvette to the next level of performance and reliability. If you take your Corvette to the track and are serious about getting the best performance possible, whether hot lapping, just cooling down in the pits or in traffic, the Coolit v2 or v3 High Speed Fan Controller is an inexpensive must have accessory because cooler is better!
