At the same time the belt is replaced the belt tensioner mechanism should be insepected. If the pulley bushing on the tensioner or spring inside the arm is weak, a brand new belt will squeal for a time after start-up. The reason this happens is the alternator is bore difficult to spin because is re-charging voltage the battery (because of the start-up) and furnishing amperage to all the car electrical systems.</p></blockquote><p></p>
