Temp.?!
 

I have a 1995 Z28 and when the car is off the motor temp gauge goes to pretty dam high up there. but then when you start the car it goes to where it should be. Is this a problem or is this just somthing that they do?!

The gauge goes up BEFORE you have started the car? As in - you wake up in the morning, go out and put your key to ON and gauge jumps to red? Or you run the car, gauge is at 210ish, turn it off and it shoots to red? Please be a bit more specific if ya could.

I have noticed that, if the car is already warmed up, when I turn the key to on (engine off) the temp gauge will rise, and then after I start the car it slowly falls back to normal.

after it warms up. sorry. after i have driven it and it has completly warmed up it goes to almost red when its off but when i start it it goes back to where it should be.

i wouldnt worry about it.get a real gauge and see what it reads

Or at least check it with a infrared thermometer. The stock gauge is not all that accurate.

Mine does same thing i think it gets heat soaked. Mine has like heat shield attached to the hood so that don't help it. I replaced my Thermastat last year.
