I haven't been doing much heavy lifting as far as the cars go lately but decided to dig back in on the '78 240D, which has been sitting for months. Basically it was leaking coolant from (I am pretty sure) the t-stat housing where it junctions with the block. Since I have a York compressor, it's a gigantic pain. I haven't been able to get any tool on the lower t-stat housing bolt because of the bracket. Finally today I decided to just take the bracket and off. I removed the fan and all the bolts that I know of, but the bracket will not budge. I tried hitting it with a rubber mallet and prying it with a pry bar, with care not to damage anything in the vicinity (except myself). What am I missing? Here is what is removed: Two large bolts from the front of the block to the bracket, two small bolts from the front (behind the fan), one large nut to the exhaust manifold and two large nuts down on that little leg of the bracket that heads toward the oil pan. Won't move in any direction. I don't even think there's any rust there, because there's so much grease around it over the years. Anyone else encounter this?
