[Shotimes] Radiator OverFlow?

[Johnsho92]

Hello all,

I have a problem on two of my SHOs, one is a 1995 MTX
and th eother 1993 MTX.

Both of them have the same symptoms, overflowing
through the water bottle..   Wierd, it doesn't over
heat or anything.    

I would fill the Water bottle to the right level,
drive it around for 20 miles or so, and everything
seems fine.   But I can sit there and watch it slowly
pour back out of the water bottle.  Sure No problem
here, yet.   But them I would continue to drive later
on and the bottle is emptied, as if the system sucked
it back in but now leaving the bottle empty.  I can do
this every day and it'll happen the same..   As if the
system boils over or something?   It's not running hot
at all, Maybe at most the level goes up to 'M' but
mostly at 'L'

Any ideas people?  Thanks a lot.. :)
