Mercedes CLS55 AMG W219, Original Gates Serpentine Belt 1139970292 6K2449

Replaced the Contitech 6K2445 serpentine belt with an original Gates belt and was very surprised to see the actual difference. The ribs of the OE Gates belt are significantly thicker than the Contitech (Continental), something I did not expect to see.

Even though it’s way more expensive than the Contitech (about 70 euro vs 20 euro), I’m happy that I have chosen the Original OE option.

Mercedes CLS55 AMG W219, Replacing The Serpentine Belt

Replaced the serpentine belt, under the guise of “while I am in there”. It was quite a hassle, but unfortunately, I will do it again as this belt seems a little short to my liking. The tensioner has ample room to move this way, which is not how I like to see it.

I replaced it with a Dayco 6PK2440 belt if I am not mistaken.
