@brianp38dse is the plunger guy.
Bleeding should be done to the letter, cut one corner may be doing it all again. Don’t try doing it with nanocom do it old fashioned way

They aren't temperature guages as such, just too cold, normal and too hot. Normal is from about 85 to.. i forget.. is it 118c?I think temp gauges are not that accurate, more of a guide, if the reading is stable over time then, suddenly goes higher, time to pull over and investigate, don't go thinking it's ok it's not in the red
Top of the brake pedal. Reach up, twist and extract. Pull plunger out. Fitting is reverse ...

Don't forget to hold down the pedal as you put the plunger switch back.

85 to about 105C on mine.

Lower hose will be at a lower temperature than the engine.

Thanks Datatek for this figures. I have been driving around dead scared for the temperature after a couple of blow outs and overheating. Having changed all that is connected to the cooling, stat, rad, water pump (twice as the first with metal impeller did not transport the water to well in my opinion, then a new with more sophisticated metal impeller that took the temp down an average of 2C) ) expansion tank cap, (be aware, one of my blow outs was probably due to the new exp. tank cap not closing properly) all the tubes that can be changed, VC for the fan ...
Always starting the Nanocom together with the engine to follow the temperature increase. Normal driving, low load around 90C to 92C. After some hill-climbing it comes up to 98C and then I am dead scared.
Obviously I don't need to be that scared anymore.
But its all for the fun of having a P38

I had my Hawkeye connected to my 99 with 4.6 while driving around and it said my temperature was 92 to 95C. This quite a bit warmer than the 180F/82C reported by my Autometer sensor located in the lower radiator hose so Datatek is correct about that flow being cooler. Can't locate the adaptor and sensor in upper hose as it needs 3 or 4 inches of straight run to replace. My gauge is more sensitive than the dash Guage and at least gives a good relative idea of what is going on.

So the RAD drops the coolant temperature by 10C. What your gauge will not do is show up a sudden overheat due, for example, to a failed water pump.

If hotter water is going to be coming out of the radiator I am sure I will see the temperature go up on my gauge. I know what is normal so any increase other than when going up a long hill would be worrisome.
