The temp. gauge on the dash stopped registering anything after reassembly. I jumped a wire across the leads and confirmed that the dash gauge does work. Ran the engine, confirmed the thermostat opened, drove the truck, and had good heat in the cab. I assumed that the temp sensor bought the farm during disassembly.

He's been driving the truck for few days and now has no heat in the cab. I was planning on replacing the temp sensor today, but now it sounds like the thermostat is stuck open.

Should the Thermostat fit snuggly into the housing, and will the wrong thermostat effect the temp sensor?

..Thanks for reading, can use all the kelp I can get.
just thought of something.....i would establish for sure that you have a 1998 2.5........and not an earlier 2.3.........I believe the timing belts and water-pumps are the same for both motors but the tstats are different......the 2.5 has the tempgauge sensor and the ect sensor right next to each other on top of the tstat housing.....the 2.3 I think has one sensor in the housing and one in da head....I think
