You probably have to go get a Haynes manual.

You will need to get an idle pully, remove the air con. pump and fit the idle pully in its place. You may be able to reroute the belt but getting a belt to fit will be a problem.

If you don't have the owners manual most of them were you turn on the ignition to run but do not start the car. Now push the gas peddal to the floor 3 times quickly. The light should start to flash then go out. Turn off the ignition and now start it the light should stay out if it comes back on there is most likely a problem in the ECM or wiring.
