Forest....If I have the car dead cold and open the cap will that take off the
pressure?  Will I just be able to use vice grips on the hoses to hold back the
coolant when I cut the line?  That was the plan.  Ned

>>>Interesting.  Please explain further?  I was under the impression that
automotive cooling systems had what amounts to a high-pressure and a
low-pressure (almost vacuum) side.  I know that it's possible to collapse a
radiator hose with suction if there's an obstruction in the radiator, for

example.  

If the down-stream side is pressurized, how would coolant be able to flow in any
direction?
