I have a 1997 Lumina with a coolant leak.  We've been able to pinpoint
the problem, it's the connection on the back side of engine, where
radiator hose #2 connects.  Bought the part for $8.00 now we can't get
to to it.. can easily see it, but can't get any tool we have into the
space and use it too...manual is useless as taking apart the entire
engine is not an option...any suggestions would be greatly appreciated!
