86 Coupe temp gauge freaks out....

[Kwattro@aol.com]

Weird experience - 
when I turn right at all, the temp guage goes through the roof, and starts 
blinking.  As if that wasn't bad enough, now it does it when I accelerate or 
hold a steady speed.  I'm not loosing coolant, oil temp is steady, and I do 
have coolant in my overflow tank.  What's up?  Guage or sensor?  Plus, if 
it's the guage, is the entire digi-dash history or can you replace one part??

Later!
