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.

Mercedes CLS55 AMG W219, New Exide AGM 12-12 Aux (Auxiliary) Battery

Decided to replace the Auxiliary battery in the CLS, as I could not find how old the current battery was and also the top was dented?

I replaced the Varta Silver Dynamic AUX14 battery with an Exide AMG 12-12 battery. Replacement is very easy and can be done by any home mechanic.

Mercedes CLS55 AMG W219, Kreezi RX11 Pro Phone Holder Mount

I wanted another phone holder, as the vent holder I was using looked “messy” and was blocking the vent. After a search, I went with the Kreezi RX11 Pro (whats in a name…) which has a strong suction cup and extendable arm.

It also clamps the phone automatically once you push your phone against the backing plate.

Mercedes CLS55 AMG W219, Broken Brake Light Switch (Intermittent)

I received the dreaded red light brake errors on my instrument cluster, so I was preparing for the worst (broken SBC computer). When I scanned for errors, fortunately it only showed a faulty brake light switch.

Mercedes CLS55 AMG W219, Black Wiper Filler Cap (Pre Facelift W211)

I always hate the bright blue caps for the wiper fluid and when there is an OEM option to change it something better, I am all ears 🙂

I was notified that the pre-facelift W211 E-class had a nice black & yellow cap instead of the ugly blue one. I was able to source used / second hand one for cheap. Retouched the yellow with some yellow caliper paint I had laying around and presto!

Partnr: 2118600064 / PUM22268

Looks way better, don’t you agree?
