Hello,
I have a 91 and it does the same thing. My wife and I went to Helen, GA a couple of weekends ago and we were in 4 miles of traffic coming into Helen. It got very close to 250 or so, I turned my air conditioner off which was bad because it was so hot outside, however this held the temperature around 250. Now once I started moving at a good clip the temperature came down. BUT, the second I get into traffic, this thing heats up.
I am bringing it in today and having the chip replaced and a 160 termostat put in. I would like it to run somewhat cooler. I have a lot of cars and none of them run this warm, but according to all the posts, most all Corvettes do this.
I am made sure the radiator is clean of debris, flushed the radiator, etc. The only thing I have not done is put the Water Wetter in which I have heard a lot of good things about. Supposed to bring temperature down 20 degrees or so?
I figured I would chime in with this also.
Thank You!
LARRY :cool
