Review on Gates 38406 Belt Tensioner by Payton Stovall

Same manufacturer/quality as OEM and I speak from over 15 years of experience with Audi. It's a shame that crap like that comes from the factory. Do yourself a favor and replace this part every 50,000 miles. Access requires removing the front bumper and loosening the radiator bracket. You can use a 17mm crow's foot with a short 3/8 extension or AST (assenmacher) Tools sell a serpentine belt tensioner wrench for this tensioner, you will need it.
