Re: Location of Eng Coolant sensor

The sensor is located on the thermostat housing. Donīt know which type of connector is used. If it has a small red tab, you have to move the tab first and then can unlock it by pressing. Without the tab you only have to press it to unlock.

Re: Location of Eng Coolant sensor

Thanks for the answer Frank, I am gun shy on this as I have read that I am dealing with two different sensors in the coolant system , so I believe.
I'm thinking that the one that feeds the dash Temp guage is a single wire, while the one feeding the computer is multi- wires. That all said and having been out to look for it per you directions , I belive I have it located,
The connector is going to give me a ration , I can see that already. Part of getting older and having been a mechanic all my life is that the strength in one's hands and fingers seems to lessen first. That's okay too, just another problem to work around and a whole lot better then the alternative.
Have a great week, you've kick started mine off on a positive note. T.

Re: Location of Eng Coolant sensor

In my manual they only talk about one coolant temp sensor. It gives its input to the PCM. The PCM in its turn controls the cooling fan speed and also gives the info to the instrument cluster for the temp gauge. My manual is for 2004 WJ, so there could be some differences with 2000 models.
What is the problem you are having with the cooling?
Have a great week you to and succes with solving your problem.

Re: Location of Eng Coolant sensor

As far as I know, there is only one...and it's where Frango suggested...right on the thermostat housing. The sensor threads in, and the plug simply has a tab you press while you pull up to disconnect. Simple and inexpensive to replace.

Re: Location of Eng Coolant sensor

Frank and Tony,

Thanks for your interest and help in solving the the problems here.
The Jeep is running fine now and the best part is how much I have learned.
The original problem did not show up as a coolant problem. The OBD lite came on after about a 100 yard drive here on the place. My wife can't back up well any longer ( in fact she has all but totally quit driving) and thus when she pulls in , I go out and turn the vehicle around just incase she wants to go back up to the house sans me. At that point is when is when I first saw the OBD on. I thought well maybe turning the ing. on/off/on might clear it. Of course that did not work, and the eng would spin but not start. Being old core I put the gas pedal to the floor and held it . It finally caught but ran rough and not more then 1500 RPM , then died. 2 more attempts and a short wait period and it started up and ran fine. I backed it down to the shop and decided that I had a fuel problem. I chg'd out the fuel Filter. Same action on start. Now I start the learning curve. I found the OBD pages on the laptop. and the Jeep Forums. On a different forum is where I think I read about having two different sensors for the coolant. At any rate the OBD link is where is where I learned so much and what the problem code meant.
Buying the sensor ($23 incl tax) was no problem, finding it and getting the connector off without doing to it what I did to the one on the fuel filter was the trick. Thanks to this forum and the help there on the sensor chg went well.
Help was and is greatly appreciated. Also like all old men I can't just say quickly what happened , I got'a go around the block to go next store ! Like i heard a preacher say one time about being told by a member of the congreation. He was told to apply the "B-B-B" principal . That being " Be Brief Brother"
Tnx again , T.

Re: Location of Eng Coolant sensor

No problem, that is where we're here for. Good to hear that the problem is solved. I think that i will apply the B-B-B principle with my wife, i only will change it in B-B-S principle, "Be Brief Sister"
