I have a 71 Lemans which yesterday refused to start. Battery is fine but every time I try to start her up the TEMP light comes on. If I had been driving her around it would make sense to me that it would come on if she was in danger of overheating but it's 40deg outside and she's standing still. I want to start working on her myself especially after getting a new engine put in a few months ago so any advice is more then welcome!
