I recently replaced my radiator and while doing so I noticed a leaky compressor where the two lines connect on top. I put a wrench on it and the bolt did turn a little. So i turn a little more ever so slightly. Then a loud bang when the lines blew off in my face. So with freon and oil sprayed all over me, I blindly walked over to the hose to wash up. After looking at the bolt the first couple of threads had stripped. But the housing on the compressor has deep threads. I put a longer bolt in and snuged it down for now. I guess I fix it in the spring. Every time I fix something I brake something too.
