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.

Do you
have the same problem?

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.
