I have a 1999 SC2 and am going to replace radiator fan/shroud. While I'm doing this I would like to change the radiator cooant. Need some advice/help. Is the drain petcock sort of hidden on the passenger side of the radiator and if so is it plastic and how likely am I to break it off trying to open/close it? If this is a "risk" (don't want to but a new radiator) how effective is it to remove the bottom hose to drain the radiator? Finally, is there an engine block drain and if so where is it hidden?
I appreciate any help.
