Chevrolet Repair: heater core 99 Chevy van, chevy venture van, chevy venture

Question
My wife informed me yesterday that the passenger side floorboard of her 99 Chevy venture van is wet. We know what that probably means. I've changed the heater core in my 97 Chevy truck,but the van seems to be laid out a little different. Ever change out a heater core in a minivan?  

Answer
Hello Randy,
Not in a Chevy minivan, but if someone else can do it, so can I...and so can YOU.
If you want to look up the proceedure, go to the public library, refference section, and make some copies from the manuals...they have them all.
Good luck, and get after it.
