I found this on Willcox Corvette and thought it might help.

Vette(s): 1979 Red L-48 Corvette with Doeskin interior, 3-speed automatic, 3.55 rear; 1986 L-98 Coupe, 4+3 Manual - Satin Black and Purple (SCCA TT/Hillclimb Car); 1993 White LT-1 Coupe, Black Interior, 6-speed

I am another one in the no flex fans club - I race in SCCA events and they are not permitted for a darn good reason. And I have had them let go, with one in particular creating a nice hole in the hood of a classic 1969 Ford LTD. A fan with a clutch will be as effective in cooling, if not more so, and is much safer. Check the clutch! Other items to check that caused some heat problems with my C3:

1. Shroud in good shape and properly installed

2. seals between hood and radiator are critical to prevent air from just spilling over the top of the radiator

3. air dam/spoiler in place.

4. if all else fails, get a nice Spal electric fan to supplement the cooling

Just my humble opinion....good luck. I had to work on mine to get it cool during NC summers.

C3: 1979 Corvette Coupe, Auto, L-48, Red/Doeskin (my wife's fave);

C4s: 1986 C4 coupe (SCCA road race car), satin black, 4+3, Z51 package, L-98; & 1993 C4 coupe, white, 6-speed, LT-1.

Rick, if you do have to replace the radiator get the direct fit aluminum one. I got mine from Corvette America but MAM and Corvette Central sells the same one. Made an amazing difference in my car! Good luck and hope it works out!

Well I let the car running and got it up to temp....then drove it for a little the temp got to just below the 200 line and stayed there.(I have a 195 thermostat) So hopefully this solves my overheating problem.
