Just wanted to say thanks again to everyone for all the helpful info on the tech forum.
Have been having a cooling problem with my '94 SC ever since I bought the car about a month ago. The wierd thing was that it would run really cool in town as long as I hit the AC switch occasionally but as soon as I got out on the freeway and jumped on it it would heat up,abovethe M in normal or higher.
I had already flushed the cooling system and installed a180 thermostat so I did a search on the tech forum and found that this is a common problem with late model SC's. I also discovered that there is supposed to be an air dam mounted below the bumper cover ,(mine was missing).
To make a long story short, I made an air dam out of some scraps laying around in my shop.It's about 35" wide x 4" tall and I mounted it directly to the lower front of the radiator core support. I just took the car out for a drive on my favorite stretch of highway and at an outside air temp of 86 and a steady 85 mph the temp never climed over the n in normal. Total cost was about 2 bucks for some sheet metal screws and washers and 99 cents for a can of flat black spray paint. The info on the website is priceless.
If you are having high-speed overheating problems and the rest of your cooling system is ok you should make sure your air dam is in place before you start throwing money at it. I'll SC you guys later,
