Review on ACDelco 38158 Professional Automatic Tensioner by Serotonin Collazo

Revainrating 2 out of 5

A true part of AC Delco. Precise fit and finish. 2 thumbs up.

*****Genuine AC Delco part*****2003 GMC Sierra - 5.3L v8 Made in Canada. Mark confirmed. Arrived quickly and left quickly as usual. Spring is good and firm. The old one felt stuck together and had trouble moving. As for OEM. This is exactly what was taken from the truck. Period. DO NOT BUY OTHER COUNTERFEIT. Always use Delco for GM vehicles whenever possible.

Pros
  • Best in its niche
Cons
  • Big and bulky
