Thanks Randy! I am going to work at it slowly for a few days and hope for the best. I ordered new bolts from Mercedes and have my drill, extractor set and tap ready just in case. Bob

A propane torch should be sufficient heat. Go slow and you may be successful in getting the old bolts out. I did it years ago on a Ford Taurus. It was my wife's car and she was complaining of little heat so I decided to change out the thermostat. Those 3.0 V6 engines has very little thin bolts holding down the thermostat housing. I managed to get them out without breaking them by slowly working them with heat and penetrating oil. It was minus 20 degrees and my garage was unheated. I must have been tougher back then. I did hang a light fairly close over where I was working to help keep my hands warm.
