DO NOT USE TEFLON TAPE HERE! The sensor grounds to the block, tape will likely affect that and could lead to other issues. The thread is tapered somewhat and seals fine at proper torque, the tape is unnecessary. Regarding the swap, if you’re putting it up in the air, it will help things. I did...

If you have the 200a alternator, I really can’t see how you would be able to do itquickly enough to not lose a good amount of coolant, but maybe if you’re quick, it’s possible. If you just changed it, you could always just dump it back in, I suppose. I needed a flush anyway, but draining it from...

Finally got it sorted- bought the updated gauge and sender from Kascar, now it seems that everything is working as it should be. Apparently the old gauge was reading about 30 degrees high. Odd failure, but I’m just glad it’s sorted. For anyone looking at making this change- you will need to...

Any chance you have NSNs? I hadn’t thought of this, either.

RWH- that was my mentality as well. If the other components function, it’s just down to the mechanical switch to complete the circuit at the appropriate temperature. That said, I will still need to get the gauge sorted before I’ll trust driving this around. Otherwise it’ll be pinned at full...

Update for today - Seeing 160 on the gauge, I'm seeing 1400-1500 Ohms at the sensor. Simultaneously I’m seeing the temp on the thermostat housing of 130 degrees and the temp gauge sensor of 130 as well. The block itself is reading about 160, FWIW. Based on that, I’m thinking that, while the...

Thank you all for the assistance here. It is appreciated. The fan is not coming on from my driving, but I’m also not seeing thermostat housing temps above 190 degrees. This truck has seen very light duty thus far- driving to Home Depot, taking the kids to the pool and on hikes, etc.- the...

Do you think I’m safe to let it run until the thermostat housing is at 220 degrees or so? I’m guessing that it’ll read somewhat lower than the actual coolant, but don’t want to risk friction welding my pistons to the block just to confirm that the fan does actually engage properly.

I made a grounding harness when I got her, but I did run into some odd oil pressure reads a few weeks ago that was fixed by checking ground and some dialectic grease, so I’ll go do some cleaning of the gauge grounds, good call. I don’t know why I didn’t think of that. Also, good call on the...

So I got that backwards, when the thermostatic switch is unplugged it turns on, when it's shorted it turns off, I had that backwards - you are correct. I just took it for a little drive and the temp began to rise, then I pulled over and unplugged the Cadillac valve, and she was resting at the...

Right, and it does when disconnected, but when the truck is used normally, it does not come on, despite temperatures appearing to exceed 235 degrees per the famously inaccurate gauge. The question I have is how do I determine what needs to be replaced or adjusted without risking overheating my...

My M1123 has been giving me a few issues with the cooling system as of late and I'm having a hard time tracing the source. Pertinents- M1123- 6.5 GEP 506 - New TDM (April 2022) and Thermostatic switch (August 2022) from Midwest Military Equipment, Cadillac valve tests at 78 Ohms, Power Steering...
