In the earlier stages of my cam swap.... I have consulted the Helm's manual and is it true there is only a coolant drain on the passenger side of the block? That seems to me that it would not drain the driver's side. I have seen reference to a engine block coolant heater on the driver's side. I doubted my car would have this, and indeed I do not believe that it does. It seems to have a plug with a allen-head (hex) so big I am having trouble comprehending it. It must be like 15+ mm..... Where do they come up with this esoteric crap??? Anyway, can anyone confirm my findings - and how the hell do you get that plug out. I think it's in a bad spot for access....
