So near as I can tell the logic on how the fan is controlled is that it engages the fan mostly for AC and the switch in the head is more of a the engine is getting to hot so let's turn on the fan

Actually it comes on at 234* and off at 211*. I understand why the fan wouldn't work for us Will I'm just surprised the GM engineers didn't think we'd need it.

So you are indeed correct as usual glagulator. There is an electric fan in front of the cooling stack . I never would have guessed. It also makes me question why the diesels didn't have one.

No problem. So to update what I've learned so far. Yes the one at the thermostat is for the ECM. I had a scanner on it and could watch it go to -40 when unplugged. Drivers side is definitely for the gauge so what I don't know is the purpose or function of the one on the passenger side.

Upstream about 8-10" there a funky plastic block that has 2 wires going into it and some sorta diode or resistor in it.

Or are they using that sensor to signal the ECM?

Wouldn't it have electric fans then?

Posted this here to get the most views/response. Helping a friend with his 95 k2500 454 truck. Has 2 temp sensors one on driver's side for the gauge one on pass side for the ECM. So the pass side sensor is broken barely all there. We cannot find the sensor that fits the plug. I've gone through...

I don't think this ever had a bolt on cutting edge until I put one on it.

Have you tried adjusting the dash lights?

Make sure the kit you get uses the ball and socket where the down pipe joins to the rest. Much easier to get it in correctly

Yes it's an older fisher with the engine driven pump but it's not the speed cast. It has electrically activated hydraulics

Does yours have an actual cutting edge on it? Mine didn't when I got it and was worn down to the point that I was concerned about getting the cutting edge on securely. Maybe it changed the geometry?

That's pretty ugly IMO. Whomever did that needs to go to their local airport and look at how airplanes with metal skins are done.

It's definitely wearing at the heel

Digital multi meter

Put a DMM on it the factory gauge may simply be off

Yes

I'm assuming the transmission pointer is off? May not be in park?
