How do you change the heater core? I know where it is, but don't know how to remove it. Some step by step instructions would help. Thank You.

Hi:
There are too many steps to try to explaine without being there, and it's too easy to miss something from here. I recommend purchasing a repair manual for the truck at a parts store. It will provide step by step instructions and pictures to help identify parts.
