Pry the tensioner pulley away from the belt slowly and carefully. If you pry too quickly, you could damage the belt.
Make sure that the new belt is installed in the correct direction. If the belt is installed incorrectly, it could damage the engine.
Tighten the tensioner pulley bolt to the specified torque. If the bolt is not tightened to the correct torque, the belt could come loose.
