RPM Extreme Engine Fan Controller Installed

[EBYCREEK]

Just installed the RPM Extreme Fan Controller on my 2021 392. Drove around for about 60 minutes and the highest temperature I saw was 207 degrees. Most of the time it was between 197 and 203 degrees. Engine oil temp has also dropped about 25 degrees. I'm hoping this will also help keep my power steering motor a little cooler. The website has now been updated to include the 392 Jeep Wrangler.

I have to admit that splicing into the factory wiring harness is a little scary. After I started it wasn't to bad. It was well worth it in the end. My Jeep has never run so cool. I've never had any engine overheating problems but have replaced 3 power steering pumps. So far my Jeep runs about 25 degrees cooler. The nice thing is it's all automatic. I was using the Tazer to run the fan on high but the noise of the fan gets old after awhile. With the new fan controller I haven't had my fan speed go above 50%. Other than the Atlas Transfer Case upgrade this is probable my 2nd best mod.
