Mercedes CLS55 AMG W219, Upgrading To The Gates HD Fleetrunner Micro-V K080510HD 8PK1294 Supercharger Belt

It was apparent that the best in Supercharger belt would be the very popular green “Gates HD” belt, but it seems there is an even better one (more on that later).

When I ordered this belt, at the moment I thought this was the best that Gates had to offer. Its very popular as an upgrade belt and you will see it being used on many M113k engines (stock & tuned).

This belt should prevent slippage (meaning lost power) and will last a long time.

Partnr: Gates HD Fleetrunner Micro-V K080510HD 8PK1294

I have a stock supercharger pulley, so 1294mm is the correct belt length.




Mercedes CLS55 AMG W219, Alignment At Daemen Bandenservice Venray

After working on the front suspension, it was time for an alignment at Daemen Bandenservice in Venray. I can highly recommend them, a true alignment (and wheel) specialist.

Mercedes CLS55 AMG W219, Replacing The Old SAI Hoses

Decided to replace the 2 old Secondary Air Injection (SAI) hoses on the front of the big V8 M113k engine. As I pulled them of, they started to deteriorate, so I was just in time. The SAI system helps the catalysts heat up faster in a cold start situation.

Mercedes CLS55 AMG W219, New Jack Pad and Airbox Isolators

Bought a new jack pad (which slots into the front subframe) as I broke it when working on the car. I also noticed that 2 rubber isolators from the airbox were missing, so I also bought 2 new ones to prevent the airbox from making contact with the surge tanks.




Mercedes CLS55 AMG W219, Bosch Aerotwin Flatblade Wipers

Replaced the Valeo wipers with fresh new Bosch Aerotwin flatblade wipers. There is a clear quality difference when you compare them.




Mercedes CLS55 AMG W219, New Coolant Expansion Reservoir

Also took the liberty to replace the old coolant expansion reservoir/tank with a fresh new one. The new reservoir was including a new coolant cap and coolant level sensor.

I have no idea when it was last replaced. Also it was leaking from the cap, even though I tried a new cap (see my previous post: https://www.ducked.nl/mercedes-cls55-amg-w219/mercedes-cls55-amg-w219-new-coolant-expansion-reservoir-cap-oil-filler-cap/ )




Mercedes CLS55 AMG W219, Replacing the 722.6 Gearbox Conductor Plate & Transmission Fluid Refresh

As part of the big preventative maintenance, I swapped out the conductor plate for the 5-speed 722.6 automatic torque converter gearbox (which is pretty much bulletproof) and also did a fluid refresh. Its almost impossible to get all the fluid out, that is done better with a flush (done with specialist equipment).

10 liters of LiquiMoly Top Tec 1800 ATF fluid
Febi Bilstein Transmission service kit (gasket, filter, bolts, drain plug, copper washer, connector)
New conductor plate
New conductor plate
Valve body & old conductor plate. See the black residue, time for some cleaning
More of that black residue…
New conductor plate fitted, cleaned the valve body as much as possible
Valvebody back in place, new filter mounted

I replaced almost 6 liters, the rest remains in the system off course in the coolers and the rest of the transmission plumbing. Maybe somewhere next year do this again, but also replace all/some solenoids and go to a transmission specialist.

Pro tip: Transmission adaptation reset is mandatory! I used method 2 of the video below




Mercedes CLS55 AMG W219, Ball Joint Special Tool

As preparation of refreshing the front suspension, I bought the special tool to press out (and in) the ball joints which are housed in the knuckle on the W211/W219 platform.




Mercedes CLS55 AMG W219, Replacing Roof Window Trim

The roof window trim had seen beter days. On both sides, the “curtains” were torn, which is something that annoyed me very much as the CLS is a luxury car.

Bought 2 new trim pieces from Mercedes, they were quite easy to replace. Start from the outside of the car with the window tilted. You should then be able to lift out the trim pieces and then continue from the inside. On the front of the roof window, a hard plastic piece keeps the trimpieces in place with a small notch.

Looks way better after replacing it!

Mercedes CLS55 AMG W219, Repairing The Airmatic Compressor to Valveblock Airline

My MacGuyver method for repairing the airline did not hold out very long, so I needed something structurally. Fortunately, Mercedes sells a piece of airline (1.5m) for repairing/maintaining the Airmatic system, which was exactly what I needed.

Partnr: 2203271045 / A2203271045
Costs: about 20 euro

MacGuyver vs new airline. I used some teflon tape for extra safety
I found some hose which fitted around the airline perfectly (also for extra safety against rubbing)
