Then, install the new pulleys from the kit in the correct positions and attach the included serpentine belts. Double - check all connections are tight. When it comes to maintenance, regularly inspect the pulleys and belts for any signs of wear, like cracks or fraying. Clean the pulleys occasionally with a mild cleaner to keep them in good condition.
