Coolant temp dummy gauge I know that the coolant temperature gauge in my car is basically a dummy light. I've been told that if you overheat it will jump from 210* to pegged.
1) Where is the limitation keeping it from being a fully functional gauge? The sensor? The computer? The gauge cluster?
2) Is there any way to make this fully functional without spending an arm and a leg?
3) If I were going to get a gauge pod for the A-pillar, would I be able to get an aftermarket gauge that would be fully functional? Or, would it require more than just a new gauge? Would I be able to keep the one in the stock gauge cluster at least functional at the same time?

I do beleive it is the isntrument gauge that is dummied down. The '98s had accurate water temp guages, but reportedly, GM had some complaints and concerns from people when the temp would fluctuate with the t-stat opening and closing, so in '99-'02 essentially the gauge is only good for "cold - up to temp - overheating".
in 93-98 the gauge got the signal from the sender, and then the computer got the signal from the sender. In 99 and up the computer got the signal from the sender and then the gauge got the signal from the computer. Somewhere along the way things got screwed up and like what was said above, it reads cold, normal, and hot.

no. do not remove the stock sending unit. the PCM uses it for quite a bit of stuff. the stock sending unit is right by #1 exhaust.
the plug we're referring to is by #8
