Intake Manifold question?

[Pennywise2]

Before taking off my intake manifold on my 96 GT.
How much coolant do you really have to drain?
Do you have to take off both coolant hoses on the radiator?
How much coolant is needed one gallon or so to replace
what was drained?
Thanks.

just open the drain plug on the bottom of the radiator, and then loosen the coolant cap, that will drain the system out for you. you will need atleast 1 gallon to refill it. most of the time I use about 1 and a half.

This is exactly what I did. I bought three gallons of coolant to refill, ended up using a little over two if I remember right (once the air pockets were gone). Anyway if you drain it the way Mike said, you won't leak any out when you pull the manifold off.
