Review on Enhanced Performance ACDelco Professional Automatic Tensioner – Model 38159 by Steven Wood

07 Suburban LTZ. Definitely recommend the product, definitely recommend the company. So far so good. Not only did the part arrive on time and fit perfectly, it also included an accompanying technical bulletin with inspection instructions and links to review worn parts for a possible cause of failure and the need for further diagnosis. In my opinion, always higher. If you have the right tools and a way to safely jack up the front of the car, my Suburban had 6 screws loosened (4 for the plastic cover, 2 for the old tensioner) and 6 in the back. Reattach the strap. (s), and AC is back in business.
