Re: electric fan/over heating

the jeep is going to run in the 195-205 +/- there is no spec for where your going to pull the temperature, but your likely not going to even pull operating temperature. as close to the coolant temp sensor as possible which is located just infront of the middle of the intake manifold IN the block. The sensor is what can be assumed to be sending a the temperature signal that your seeing on the gauge so reading as close to the sensor as possible is better.

Re: electric fan/over heating

I'm trying to understand why you think the Jeep is overheating. From my understanding you are saying the temperature needle gets to the 12'o clock position and then the fan kicks in and cools down the engine. Dead center is roughly 210 degrees F and somewhere around there the cooling fan will turn on. Someone who knows the true computer operation of the Jeep can correct me if im wrong but the cooling fans will run until the temperature returns back down to around 190 or 195F? The cooling fan will cycle its operation andwill not run constantly unless the ac is on.

Now if your jeep is getting hot to like say the '3/4' mark to the 'H' side, then i would say it is overheating. I think you are questioning if the fluctuation in temperature is normal... Dont get me wrong but what you are describing is what my Jeep does and I have the V8 with clutch fan. It happens to me when its warm out and im in stop and go traffic.

What is not normal from what you said, is that your Jeep idles really bad and starts to shake.

Re: electric fan/over heating
