The fuelies I am aware of all have TWO senders in the coolant jacket. ONE of them sends the propper temp to the gauge.
The OTHER one is a switch and sends only sends a go-nogo to the computer to tell the computer the operating temperature has been reached so the computer can change the timing and mixture from start to run... BOTH will screw into the same holes! However the ones I have seen have different lectric plugs on them to caution against mistakes in which is used.
I have seen guys making the wrong one plug into the system by FORCING the wrong plug! Needless to say the wrong sender will NOT work.

Well against popular opinion, I changed my radiator, with the AC on, in traffic, on a hot day (90+) I haven't overheated, not saying it wont today on the way home but for the past several it's been running normal

If that was the original rad. I completely agree it was time for a change....I can't recall having one last more than 7 years or so.

I have owned the Jeep for 4 of thse years, I just have a problem throwing out a radiator, that is perfect on the outside

They all look good on the outside - even when they're filled mostly solid with junk inside....Send it to the recycler... <img src="/forums/images/graemlins/cheers.gif" alt="" />
