Fits 2007 Mercedes 280

Identical in form, fit and function to the OEM Gates tensioner on the 2007 Mercedes C280, approximately $30 less than the same part number at RockAuto. Made in Turkey.

Pros
  • Best
Cons
  • 0

High quality belt tensioner!

I recently replaced an old belt tensioner in my MB E350 4-Matic with this ACDelco professional automatic belt tensioner 38319. Works very well and smoothly. I prefer ACDelco components.

Pros
  • Great for a small home
Cons
  • No instructions

Rattle, won't hold full tension

Just installed it and heard a knock under the hood from my mechanic, opened the hood and found that the tensioner wasn't holding full tension and bouncing back and forth and made noises. waste of money

Pros
  • Rugged finish
Cons
  • Nothing here

Bait and switch, Revane, do you want pictures of what you sent me?

I don't like paying more for an AC Delco tensioner that also came in a box with AC Delco tags only to open it late on a Saturday night after doing other work and found that I was sent a product from a commercial Gates brand. None of the local stores carry this part, so I have no choice but to use it, even though Gates' last tensioner lasted less than 50,000 before it started falling apart. I feel like I'm owed the difference between the two brands which is $35 which doesn't include my work if…

Pros
  • Great for me
Cons
  • Minor issues
