I'm working on a 1988 Dodge Class B, with the Ram 350 chassis. It has the 360 V8, with 55K miles on the clock.
Here's my problem: The temperature gauge has a mind of its own. It "normally" runs one notch below the mid-way position between "C" and "H". But frequently the temperature gauge stops working, and the gauge needle drops down off the gauge to way below the "C". There is no pattern of it doing this. The gauge will work fine for several hours, then stop working. Sometimes the gauge will indicate way below the "C" when I first start the engine,and stay there. Then, eventually, the needle moves up to the "normal" position, one notch below the mid-way position between "C" and "H". After driving a while, sometime the gauge works fine, and then it stops working, and then starts working again.
I'm thinkig the sending unit has gone bad, but thought that I'd check and see if anybody on the forum had this problem and "been there, done that".
