If you're replacing it, I can't help you....in fact...no one can. 
Anyway, if you bypass the heatercore make sure all of your hoses are out of the way when your done. This sounds like common sense, but i burned through one of my hoses this morning...coolant was spraying everywhere. It was a horrible thing. Replacing the hose is no problem, but just a thought if you dont want to have to replace any hoses.
