Why We Installed Electric Fan

Here we go over how we wired an electric fan with thermostat control that turns only runs with the ignition on. We are installing this because after we installed AC, we now have heat issues while not moving. Once driving down the road the heat issue will go away due to the airflow of movement, but this is not a good solution, especially on the trail.

Improvements After Electric Fan Install

We did not install an electric fan for more HP, Torque, or better MPG, but we did see improvements even if sight both with the New AC on and off. We didn’t Dyno the jeep, but the in the seat acceleration from a stop had a noticeable difference with our little 2.5L Jeep engine. The MPG just with the little driving we have been doing has improved about one MPG, with fuel prices right now every little bit helps.

What We Have Done To This Jeep To Improve MPG And Performance

The fan is not the only thing we have done to this Jeep, we have a lot of YouTube projects, so your results may vary from ours. We did the greatest performance gain project on this Jeep was the gear change going to 4:88 from 4:10. We have also replaced every senor, filter, plug, etc in Youtube videos making this little jeep run great.
