- The only reason not to remove it is that it ay be illegal in
- your area, After all it is just an air pump pushing air into your
- exhaust manifolds. If you only take the belt off exhaust can flow
- back into the pump andbuild up carbon deposits. Then when you want
- to reconnect it for an emmissions test it will not turn.
