Coolant system drain plug on 5.0
I'm planning to put on Goodyear Mustang HO blue radiator/heater hose set on my 87 TBird 5.0. I'd like to drain both the radiator and engine. I keep reading about a drain plug on the engine block but have not seen or read any description of its location. Where is it? ...and after all these years is it a wise choice to even touch the thing? For that matter should I even attempt opening the radiator petpen 15 or just take off the bottom rad hose and leave it at that? Just trying to avoid any unneccessary lost time. Your experiences are appreciated.
