Re: Cannot find correct coolant temp sending unit

I will say that the old existing sensor is still sending a signal - just an incorrect signal. I guess I could continue looking for an abnormal spike in the gauge relative to its typical setting (135-150 degrees?), but I am very anal about things like this. A big block in the 110 degree ambient desert climate makes me nervous about overheating this beast, so I keep a close eye on the temp gauge. Every part of the cooling system has been replaced, but it doesn't take much of a part failure to roast that engine.
I missed that part the first time around. What does the gauge read now with the engine at normal temp? You mean it reads 135-150 at normal temp?

I have also been assuming a stock GM gauge, in the dash. Is it?
