I recently purchased a pristine 2007 S65 AMG with 50,000 miles. However within the first 3 months I started feeling the driver's side engine mount had given up the ghost and was now relying on the strap to keep the engine from leaping up. I downloaded the Mercedes AR22.10-P-1260SZ engine mount replacement procedure however I found that at least for me it did not work. So I wrote up my process in the hopes it will help others.

 

Sorry for resurrecting an old post but the write up is so good I must say thanks. This gives me great confidence in DIY-ing the engine mounts on my w221 s600. Thank you.

 

I watched a few years ago and I do not envy having to do that job.

 

I did the engine mounts of 2009 s600 last week using this guide and it was a success! I want to add a couple of details that weren't mentioned in OP's guide that might be helpful for others.

First, WIS says you need to disconnect a whole bunch of components before you can raise the engine. I got impatient and raised the engine without disconnecting anything. I raised the engine with a jack and some 2 by 4, did it little by little while feeling around hoses to make sure they aren't stretched or pinched. It turns out the engine can actually be raised high enough to change the mounts without disconnecting anything. The top coolant hose was a bit stretched but nothing crazy, the driver side bottom ABC hard lines were also under a bit of tension but the hard lines all have some portion of rubber soft lines, so no big deal. However, you definitely need to use your judgement here as the condition of each car is different, don't blame me when you ABC high pressure line bursts and costs you $2k lol

Second, for the driver side mount, you don't have to do anything to the steering coupling. You don't even need to remove the heat shield. As mentioned in OP's guide, you need to rotate the mount assembly, use impact gun to dissemble it in place, and remove the bracket and the actual mount separately, from the front (not from the rear, so no need to touch the steering coupling, you'll know what I'm talking about when you are under the car staring at the driver side mount).

That's it, all else went as planned exactly like OP's guide. Passenger side is super easy. The most difficult part is definitely raising the engine just enough to change the mount, and not too much where you damage some hoses or lines.

Oh lastly I used Febi Bilstein mounts (29511) and they fit perfectly, since the OE corteco ones are out of stock everywhere
