Mercedes CLS55 AMG W219, Replacing The Engine Mounts With Meyle Mounts

As part of further preventative maintenance, I replaced both the engine mounts with fresh new Meyle engine mounts. Unfortunately no HD version available. Next time I will probably replace them with Mercedes Black Series mounts, as these are a popular upgrade.

It’s highly recommended to replace them, as it makes a major difference!

New mounts with the covers
Meyle (new) on the left and old on the right. I almost thought that I ordered the wrong ones as there was a clear height difference. But they sag over time, so that is to be expected.
Its highly recommended to have this tool ready as this makes it a lot easier to undo the top nut!



Mercedes CLS55 AMG W219, Servicing The Supercharger Oil

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, Meyle HD Gearbox Mount

Engine mounts are usually forgotten as a maintenance item, but not for me! I checked my options and found that Meyle had an upgraded mount in their product line. The upgraded series from Meyle are known as the “HD” series and they are OEM+ replacements.

I chose the Meyle HD gearbox mount to replace the factory Mercedes mount. Fitment 100% and the build quality looks to be very good. The front engine mounts will be replaced as well by Meyle mounts!

Mercedes CLS55 AMG W219, Andreas Kawula Built My Engine!

With help of a forum member on Seat-Online.nl, I was able to find out that Andreas Kawula hand built the magnificent supercharged V8 in my CLS55 AMG. His signature is very hard to decipher, but the internet delivers again and verified that his name is indeed Andreas Kawula.

Fun fact: only the 55 & 63 engines were hand built. So a big thank you from the Netherlands, Andreas 🙂 !

Mercedes CLS55 AMG W219, New Intake Pipes (Gold Tape Heatwrap)

Noticed that one of the plastic intake tubes was broken, so I replaced them both. Fortunately, the intake pipes only costs 11 euro per piece, which is a steal!

I added gold plated tape, to fend of radiating heat and keep the incoming air as cool as possible. Took quite some time and effort, but I am happy with the end result and how it looks in the engine bay.

Mercedes CLS55 AMG W219, Special Tool For Replacing Engine Mounts

Bought a special tool, which is particularly handy when replacing the engine mounts on a CLS55 W219 or E55 W211. The exhaust manifold takes a fair bit of space on each side of the engine and there is where this tool comes in handy with removing the bolt which sits directly under the exhaust manifold (on each side).

Bought it from eBay: https://www.ebay.com/itm/125234922812

Volvo S80 2.4T Thermatec Teflon Intake Spacer (PTFE)

Bought a Teflon (PTFE) intake spacer for the intake manifold from Thermatec. It will isolate the intake manifold from the warm engine, which will result in lower intake temperatures. The phenolic spacers are identical in function, only the material used is different.

Lowering the Intake Air Temperature (IAT), will result in higher power figures. A simple supporting mod, which is quite inexpensive.

Pro tip: make a small indentation in the top left corner of the spacer where the bolt would go through the spacer/gasket (where the thermostat housing is), this will make the installation a lot easier due to the restricted space in that area.

Volvo S80 2.4T New Engine Mounts

When you have an older car, always think about replacing the engine mounts. They are almost always made of rubber, which becomes brittle over time due to aging/drying out.

I replaced all the engine mounts, which tightens up handling and improves performance and reduces strain on components like the exhaust, as the engine swivels way less. Highly recommended!

Volvo S80 2.4T Old vs New Coolant Expansion Tank

Bought a new Febi coolant expansion tank as the old one was tatty, old and brown.

Looks better in the engine where no one else looks, but me 🙂

Volvo S80 2.4T Changing Spark Plugs (NGK K20TT 4604)

Fitted some fresh new plugs and decided to try NGK copper plug instead of Volvo OEM Iridium plugs. They work great and cost next to nothing. Decided to try NGK K20TT 4606. Double checked the gap to be sure, they are correctly preset for the Volvo S80 2.4 / 2.5T.

Still have to get used to swapping out 5 spark plugs instead of the “usual” 4.
