I'm sure Ken's method would work great and it is a good idea to change you
coolant.
But when the o-ring on my '86 GL gave out this winter I didn't have to clamp
off, cut or remove the coolant lines. I simply took off the filter, double
nutted the shaft and then you can take the "box" out, replace the o-ring and
put it back together.
Good luck,
Tom

Ken certainly knows more about all things mechanical than I do, but why
would you drain you coolant and then have to go through the whole system
bleeding process when you could just clamp off the lines and top up as I
have suggested?
