A friend told me about this website with a lot of instructional videos (how to). I know this video has a Mustang that overheated but I guess it could happen to a Cougar. Be prepared if it does and know what to do. Knowledge is power and this video has great information. The entire site has a bunch of how to videos for just about everything.
