4. Swap the old pulley with the new one. Align the mounting flange and secure it with the original bolt.
5. Tighten the bolt to spec. Reinstall the tensioner, belt cover, and any other removed components.
6. Reconnect the battery and test drive. Verify that the pulley spins smoothly and that there are no abnormal noises.
