Does not meet automotive expectations

According to my experience, this tensioner failed to meet the standards I expect from an automotive product. The installation process was frustrating and the overall durability of the product is questionable. While the price was reasonable, the subpar performance outweighs any cost savings.

Pros
  • Reasonable price.
Cons
  • Frustrating installation process, questionable durability.

Happy with the results

Installed this on my Caddy along with a new V-ribbed drive belt and it really helped reduce belt noise. Happy with the results.

Pros
  • Best
Cons
  • Ugly packaging

Revainrating 5 out of 5

Keep your GM car completely GM.

Works the same as the factory tensioner and results in a noticeable increase in performance of the accessory drive, including the A/C compressor and alternator. Delco parts always seem to be the best, especially for my Cadillac.

Pros
  • great product
Cons
  • something different
