Toaster, I did not see them in the actual process of moving the engine mounting.Do you know how the engine was moved back? Looking at the engine mounts, I don't see any forward/backward adjustment. Was it the engine cradle that was moved?
I was there under the car as they showed me the loose radiator and condenser the last MB smart center left after replacing the entire A/C hose system.
They were showing me that there was now clearance and my hose did not touch and they did not touch the hose, itself....cause I asked them if they shortened it. They did NOT shorten it, they just explained how the motor mounts wear, and drop the engine as they wear. So, they re positioned the motor, and gave the clearance that way. Maybe there is a tech on this forum familiar with this particular fix for the hose rubbing . I am sure this is quicker for the tech on a slight rub like mine, not needing a replacement, to do this repositioning.
Hope this kinda helps, but again, I wasn't there when they did the actual work. This was a post-op visit under the car with the tech and the service manager.
