Mercedes CLS55 AMG W219, Servicing The Supercharger Oil

Posted in Mercedes CLS55 AMG W219

One of the most common overlooked service items, is replacing the supercharger oil. The gears of the supercharger spin very fast and need proper lubrication and cooling. Because it spins so fast, it requires a special type of oil: Mobil Jet Oil II (Synthetic Jet Engine Oil).

This oil is not that widely available to customers and also not very cheap. I used a 150ml syringe with some hose to extract the oil and fill it up again. It holds 150ml maximum, but you can never get all the oil out unless you remove the supercharger. I removed about 130ml, and put back the same amount in fresh oil.

Used a plastic containter to hold the oil in, which makes it a lot easier

Mercedes CLS55 AMG W219, Replacing The Serpentine Belt

Posted in Mercedes CLS55 AMG W219

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.

Mercedes CLS55 AMG W219, Cleaning The Belly Pans

Posted in Mercedes CLS55 AMG W219

After changing the oil, I was left with 3 dirty belly pans. Actually, the first one was pretty clean. But the 2nd & 3rd were really dirty due to oil leaking and dirt accumulating on that oil.

But a good degreaser and pressure washer work wonders. I totally forgot to take ‘after” pictures, so you will have to believe me on this one 😉

Mercedes CLS55 AMG W219, My First Oil Change With LiquiMoly 5W40 High Tech

Posted in Mercedes CLS55 AMG W219

Performed the first oil change on the CLS55 with LiquiMoly High Tech Low Resistance 5W40 oil. Bought 2x 5 Liter canisters, as the big 5.4 Liter takes about 8.5 Liters of oil in total. Also added in 1.5 canister of LiquiMoly Ceratec, a well known working friction modifier.

List:

  • 2x 5 Liter LiquiMoly High Tec Low Resistance 5W40
  • 1x Mann Oil Filter HU718/5X
  • 2x Mercedes Oil Sump Plug A3529970032
  • 1x Katsu Oil Filter Wrench Set

This was my setup for the day, used 2 ramp, which has enough ground clearance.

This is how the oil filter looked. It was in a bad state, seems the previous owner skimped out on maintenance…The rubber O-rings especially were very old and worn.

The M113k engine has 2 sumps, a front scavenging sump and in the back the main sump. I saw a lot of oil leakage, most of it was due to the rocker covers as far as I could judge for now.

Putting the Katsu oil filter wrench to good use. I used a combination of a vacuumpump with the drain plugs to get most of the old oil out

Performed some other things “while I was in there”, but I will describe that in separate posts.

Mercedes CLS55 AMG W219, Replacing The Rear Differential Oil

Posted in Mercedes CLS55 AMG W219

1.5 Liter of 75W140 GL5 Differential oil (LiquiMoly) and 2x new filler caps for the rear differential. I didnt have the correct hex key, but a T70 torx also works. Will be doing this again in the near future, so all the old oil is replaced with new oil.

I used a big syringe (150ml), which actually worked out very well. I will always recommend using new plugs whenever you notice that the plugs look old.

Mercedes CLS55 AMG W219, Replacing The Rocker Cover Gaskets

Posted in Mercedes CLS55 AMG W219

When I replaced the spark plugs, I noticed some massive oil seepage/leaks from both the rocker covers. I bought the original Mercedes liquid sealant for the breather chambers. I already read that this would be cumbersome, and that was no lie.

But it’s all in the preparation (degrease properly!) and take your time for that, because this is not something you want to do a couple of times.

OE Mercedes sealant partnr: A003989982010

I found out that a deep 18mm socket and 1/2″ extension enabled me to use a kit gun, essentially making the job way easier! If you look closely, you will see the setup in the back of the photo.

Happy to see that all looks well under the rocker covers 🙂

Mercedes CLS55 AMG W219, Replacing K&N Air Filters With OEM Paper Air Filters

Posted in Mercedes CLS55 AMG W219

Replaced the K&N drop-in filters with OEM paper filters (Febi Bilstein), as I prefer better filtration over a little more throughput. I don’t think I will notice the difference with my standard CLS55 AMG.

Mercedes CLS55 AMG W219, Replacing The Cabin Filter With Mann FreciousPlus Filter

Posted in Mercedes CLS55 AMG W219

Replaced the cabin filter as I did not know when it was last replaced. I was unaware that Mann had a new type of filter, which transcends the pollen and active carbon filter type.

Their FreciousPlus series is also anti-bacterial, making you stay as healthy as possible within your car 🙂 I used Mann FP3172 for the CLS55. As you can see, it needs to be replaced every year or 15.000km.

Mercedes CLS55 AMG W219, Replacing All 8 Coil Packs

Posted in Mercedes CLS55 AMG W219

After about 187.000km (or 17 years), the original coil packs are due for retirement in my garage 😉 Car seems to run a little better after placing the new coil packs!

Could also be placebo effect… 😉

Mercedes CLS55 AMG W219, New Vband Clamps For Non-Resonated Catback Exhaust

Posted in Mercedes CLS55 AMG W219

On of the previous owners clipped something, as the Vband clamps for the non-resonated catback were damaged and therefore leaking (a little bit).

I replaced both of them with brand new clamps, so the seal is airtight again!
