Got a temperature gun -- Measured the cooling system
You are totally correct. Gonna bypass it for now since were getting into summer.
I just want to simplify things as much as possible right now until this gets sorted.

You realize that unhooking heater core hoses makes you have to start over bleeding the system? Adding coolant through the bleed screw only works if you keep the system closed, it is the final step in the process only to be done when the engine is stone cold from sitting overnight.
By bypassing the heater core you are essentially starting over so no need to do the bleed screw thing until you are done experimenting.
If it helps you isolate a problem then fine, but keep this in mind, you're wasting time doing the bleed screw trick and then reopening the system.

Sounds like a manufacturer made a boo boo on labeling their temp’s to the proper batch for sure! Very easy to do during the assembly process.
Best way to avoid any issues like that = boil the sucker before installing it vs spending all that time tearing it apart and doing the job several times.

Ugh, well the new britpart is in the car so.. yeah.
Something i was pondering though -- I measured the sensor on the lower intake manifold (which is new) and while it was reading 215 on the UG the brass fitting itself and the hard coolant pipe going into the lower IM was about 120ish. I IS CONFUSED
Is the lower IM temp sensor the only one that feeds signal to the UG / temp gauge?

I second this .I have a temp sensor just hanging under my truck .I just assumed it was to the outside temp measurement, now I'm a little more nervous. Lol I've glanced, not looked hard, at the bottom of my radiator and don't see where a plug could even go. If this is the lower temp sensor, is it possible, that where the sensor goes has a plug in it and I'm just not seeing it? Mine runs pretty warm on average. OBD scanner clocks it anywhere from 190-230. Temp Gage just stays in the middle .
