Mercedes CLS55 AMG W219 – Worn Serpentine Belt Tensioner Pulley (YouTube)

When you know its time to replace a worn serpentine belt tensioner pulley.

I changed it after 190.000km (118.000 in miles). Also see my previous post about the replacement tensioner from Trucktec Automotive with a steel pulley.

Mercedes CLS55 AMG W219, New Serpentine Belt Tensioner

What do you do when you have a noisy serpentine belt tensioner? You replace it with a new one off course! Never skip an opportunity to buy new shiny parts 🙂

I was able to find a Trucktec Automotive tensioner for the m113k engine, which has a steel pulley instead of the known-to-fail plastic pulley. It’s an easy DIY task, the most time is spent on removing parts to get access to the tensioner.

Mercedes CLS55 AMG W219, Installing The Best Supercharger Belt, The Gates K080507RPM

Installed the best supercharger belt you can buy, the Gates RPM series. RPM standing for: Racing – Performance – Muscle.

As I am driving with a stock setup (stock supercharger pully & stock crankshaft pulley), the correct belt is the K080507RPM. I also made some comparison pictures, as I seem to have collected all the Gates belts!

  • Mercedes Benz Gates OEM / A1139970192
  • Gates Fleetrunner / 8PK1289HD
  • Gates Fleetrunner HD Green / K080510HD
  • Gates RPM / K080507RPM 8PK1289

The RPM belt seems to have the most “grippy” material.
