Why would it do it only when it gets to temp?

Ok so it has nothing to do with overheating? The only time it would do it is when the temp would go up? Also do I need to do anything to burp the engine or will it sort it self out? also it seems like the sensor is at the top of the radiator isn’t that an odd spot to get a reading for low level? so whats the fix just a new sensor? The coolant level has always been full btw

Is the temp sensor for the gauge on the radiator. And the one for the warning system on the coolant manifold? Any way to test them besides temp gun

I’ve got an 89 R model with an e6. In the winter my dumptruck would run cold and now things are warming up it would go up in temp and the I’d get a shutdown light and buzzer. Mainly when I was loaded on a warm day. I figured it was time for a thermostat. I just replaced it and now it warms up quick and holds an even temp however the shut down buzzer and light are on. My question is could a temp sensor to the warning be bad? The temp on the gauge is 155 but im not sure the accuracy of the gauge….

Ok, that’s the one I saw that was cut then. I assumed it had a Speedo cable because the tach was a cable and all the parts say Speedo/tach cable

What’s up guys, so my truck had a t2080 swapped form the original t2090. The Speedo and tranny temp doesn’t work? I haven’t taken a deep look. It looks like the wires to the temp was cut. my question is are the sensor and cable the same for Speedo and temp? Or do I need to switch and will the temp gauge still be good? I’d assume so but figured I’d ask

Yeah I ordered the book but it takes a couple of weeks to come in. I’m trying to get my truck to pass safety right now so I can use it. So far I’ve only see one relay from the factory and both in g aftermarket on the truck.

Ok more info the headlight/parking light switch first pic seems to turn the headlights on in either position the second switch on top of the dash seems to do nothing

Yeah I sprayed some terminal cleaner and scrapped it around with a pick

Headlight high low mounted to the floor

I noticed someone added a side marker onto the dimmer on the buss nest to the headlight could that be interfering with it?

Yeah I checked there for breaks the hinge area

So there is a harness that has brown and yellow (same on the dimmer) it shares another harness in the same loom that is a bunch of greens I think it piggy backs to the other headlight. If I disconnect I either lights got out. The green connects to bus next to steering shaft that is 10-14

And one of this harness does connect to the bus on the firewall

Looks like a harness comes out of fire wall splits into two harness and leads to a bus next to each headlight
