Review on Gates 39120 Belt Tensioner Assembly: Optimal Performance Guaranteed by Troy Robinson

Fast delivery within one day. There was a loud noise when the air conditioner was turned on. I thought it was the compressor clutch. I took a stethoscope, listened to the compressor, a thud, attached it to the belt tensioner and it looked like a woodpecker knocking. It took about 15-20 minutes to remove the old tensioner and install the new one. Perfect fit for my 2006 Dodge Dakota 3.7L. Now it's smooth and quiet.
