I've seen alot of people ask about the belt squealing in their cobras. I think I may have found a possible reason for some of these occurrences. I noticed that my belt began to squeal badly after i detailed my engine with simple green. I removed the belt and lathered it with WD40 and let it sit for about 30 minutes. After that I wiped down the residual oil reinstalled and started it up. Of course the oil made the belt squealed even louder so i drove it around for a little bit and it soon stopped. Well I just recently detailed my engine again and the squealing started up again. Instead of going through all the crap again with the WD40 I just bought a new belt. When I put the new and old ones together it looked like the finish on the rubber was very different. I have a feeling the strong base in the simple green eats away at the finish of the belt and dries out the rubber. From now on I'll be detailing with the belt off. Hope this helps.:-D
