I just bought a 94 explorer. The temp gauge barely rises. It does move slightly, then it decreases to about nothing, then rises again. The heater works outstanding, coolant looks great. Any Input? Thermostat? Gauge? thanks

Id check the sender on the engine first, make sure the wires aren't loose at both ends.

Aussiblue

thermostat.

I checked the wire at the sending unit, it appears to be attached and in good shape. Is there a way that I can take the wire off the sender, ground it to the block and then check the gauge to make sure its working? Will the guge move if I do that?

I changed the thermostat and sender today. Tough job without the right tools. But, the gauge now reads correctly in the normal operating range.
I did have to take the serpentine belt off and loosen a bracket that hold the air conditioner plumbing. I did obtain a flexible shaft ratchet that made things much easier. Thanks for all the help.
