I'm still trying to find the radiator draincock on my 2000 Saturn station
wagon with the 4 cylinder engine. As I stand facing the car, I look to my
left at the bottom of the radiator and I see an ivory colored plastic piece
that appears to be a plastic bolt, but this piece appears to be made so that
it can be tightened, but not loosened or removed, kind of like those one-way
screws that they use on toilet stall doors in public restrooms. Is this the
part that I have to remove to drain the radiator? Thank you.
