    The belt that drives the air pump for my exhaust system needs to be replaced, but I don't want to replace it. Are there any draw backs to just leaving the belt off?

    Usually once the AIR pump is disconnected, next time you hook it up, it will fail. Thats pretty standard. If you are going to undo the belt, may as well remove it. There is almost 0 gain from removing the AIR pump however, if it is operating correctly, and will harm you on a visual/sniffer emissions test.

    I did not replace the belt on the air pump, but I left it connected to the hoses that went to the headers. The exhaust came back up those hoses and destroyed the air pump (it had a plastic top where the hoses connected to it). Luckily, I have a friend who smogs it for me now so I don't need all the parts for the visual inspection I just have to pass the sniffer test.

    Anyway, if you don't replace the belt, disconnect the hoses from the pump and put bolts in them. Even then, you may have to eventually replace those hoses if they get a hole burned in them.

    That's because I'm the devil.
