Motor Mounts replaced and radiator won't realign

I just had the motor mounts replaced and the radiator shifted to the right and will not align.  I am now experiencing a growling sound and vibrating when I accelerate...  I am taking it back to the mechanic on Monday, but would like to know more as to the cause.  He asked if there was any front end collisions or bumps, and the answer was/is no.  Did they cause this issue?  I noticed that when I arrived, only the right side was jacked up as they were replacing the bottom mount.  I thought that the vehicle should be jacked from the center when replacing the mounts???

Any insight would be appreciated and most welcomed!!!  I just need to know what the heck happened.  It was fine prior to them changing out the mounts, now I have a problem!
