Well guys, guess I should update the thread to the situation....
I don’t totally get have my truck fixed the proper way like it was stock but at least I got my temps figured out, it warms up much, much faster and runs around 200°, and my fan works.
Nobody’s messed with that sensor yet that is on the lower front side of the thermostat housing that goes to the computer but, after finding it out on my own, I figured out that up on the top of the thermostat housing where the upper radiator hose comes in, there is a threaded plug right to the right of it... and of course, right to the right of that, is where the temp sensor goes that goes to the gauge on the dash..... y’all know, it’s the hole that had the big ole, slopped together 5 or 6inch threaded-together fittings with the T on it when he originally had the temp sensor on top, and the added in, old school fan switch threaded in on the side....
Well, I told him I found out about that plug and that at least for now, until our other independent mechanic has a chance to mess with it and fix the damn thing the right way, he pulled that plug and put the fan switch in that hole so now, there’s no more chimney, lol, there’s no more air pocket causing the false readings on the gauge, and it all works, it’s just that the fan isn’t currently being controlled by the ECM, it’s actually being controlled from a heat switch, just like how the ole pre-2000 year model trucks were before their ECMs got as complex as they did like my 2004 model.
Anywho, I’ll report back later someday with it fixed right...lol.
