[Shotimes] Overheat - Part II

[Rich Edelman]

This is actually pretty much the exact same problem I have with my 95 ATX that 
I posted about a couple days ago.

I changed out the T-stat today. Justin Schick and I did the plug wires and new 
plugs too, since I'm at 87K and was running on originals. The car idles MUCH 
better now. :)

I don't suspect the ECT as bad or the temp sender, as when the temp gauge 
reads slightly above the "R" in Normal, the high speed fan kicks on. It also 
kicks on when I hit max a/c. My water pump is 18 months old and I get good 
pressure on the upper radiator hose.

So Justin and I really think it is the radiator in my car. I've already priced 
new ones, and for $150 I think I can't go wrong.
