I took delivery on my first Corvette last week - a 1996 Collector Edition and of course I couldn't be more pleased. I'm working what I think might be an overheating problem and could use some advise.
I am basing my comments here on the stock temp. guage in the dash - the guage has a 185 & a 260 degree marker indicator with two equally space tick marks in between. I'm assuming each one to be 25 degrees so I'm assuming 185, 210, 235, 260 on the guage.
The day time temps. in Dallas have been about 90 degrees as a reference.
On Saturday night while driving to the IRL race - country road, no AC, driving between 65 - 75 MPH the temp. seemed to reach around 250. Leaving the race, in idling traffic to get away from the track it almost pegged the needle. Sunday I looked things over and found what appeared to be a bird nest pressed into the radiator cooling vanes. The same for the AC cooling unit (the radiator looking thing in front of the main radiator). I cleaned all of that off with my shop vac and a brush.
Today while driving to work without AC it went to above 235, coming home in 90 degree temperature, and AC ON is also got close to 235. There does not seem to be any overboiling into the overflow tank.
Coolant level seems fine with plenty in overflow tank. Fans come on with AC turned on. Fans also come on once the guage reads somewhere around the 235 degree mark. I've read in a service manual that the primary fan should come on at around 219, second at around 230 or so.
I could sure use some advice on this. Thanks in advance.
