SteveL: by down pipe I assume you mean the turbo dump pipe..? Do I need new gaskets or anything (if the old ones are A-OK)? No hoist here unfortunately, but that's never a problem with a little persistence
It sounds like dumping the coolant from the block is a PITA. What I might do is just dump the coolant from the radiator first, then remove it so I can drop it off at the radiator place, come home and then do the block... otherwise the radiator place might be closed by the time I finish (judging from your description of how hard it is to get to the block drain plug) See any problems with this method?
Finally, any thoughts on my second question regarding the ignition being set to ON?
Jordan: Thank you, but I really do believe in doing things properly which means the radiator has to come out to go to a radiator shop to be flushed. By the way, you really should use demineralised water, not that crap that comes out of our taps that's called "water" .
