I've said it before and I'll say it again: When replacing your temp sending units, don't buy the ones from Auto Zone, Pep Boys, etc. Buy the correct MOPAR sending unit. Chances are if you buy from one of the non MOPAR folks, you'll get a GM unit that is not set up for MOPARS. I made that mistake and it took me forever to figure out that my "new" sending units weren't good for my car and always read higher than the actual temp. Get the correct PN number for your MOPAR and then buy only that one.
