I tried to search but can only find info on Derale transmission coolers.
I've got a 1999 TJ Sahara the the original owner put a snow plow on and left it at their cabin in the garage most of it's life.
I bought it a couple years ago and was thrilled to have found a Jeep in the Black Hills of South Dakota that hasn't been off road!
A TJ isn't' exactly an ideal snow plow vehicle but it's been really useful that's for sure. When I drive it from my house to my cabin even running 55 MPH the plow blade blocks enough air that the Jeep will over heat. So I just added a Derale fan kit.

OK finally getting to the point of my post... LOL
The thermostat sensor for the kit engages the fan at 199.6 degrees and shuts off at 188.6 degrees. The measurements taken with my code reader.
I've read on here the 4.0L's operating temperature is ~195-210 degrees. Seems to me that the sensor is engaging the fan too soon and bring the temp too low.
So I emailed Derale to see if maybe I have a bad sensor or they packaged the wrong one in my kit. The guy answered back:
"If the temperature was verified at being over 190 and the sensor did not engage it would seem as though it is bad. We will need a proof of purchase sent to us that is within 1 year of the original date of purchase and we can send out a replacement."
In my mind that is going the wrong way, even cooler than what I think it should be at. Am I misunderstanding what is going on?
Anyone else on here have the Derale fan kit?
