as a rule I've saved every part (unless a wear part like bushing or rotor) that I've replaced on my merc. Partially in case somebody wants it later, partially as a forensic file, partially out of curiosity. Also, sometimes the new parts crap out and I go back to the old part and see if I can fix. (prob not in the case of a commodity part like a temp sensor though)

Next problem I have to face is whether or not my incorrectly clocked (upside down) R4 is going to explode due to lack of proper lubrication. Sure don't like the sounds of the grumbling - thinking of replacing compressor with correct when I switch from the r134 to my r12 supply (now that I know the system is clean and tight). System cools great though.
