Question
what size is a 1998 venture vans radiator..1 inch or 5/8.

Answer
    The only way to tell for sure is to measure the old one.  The Venture had a heavy duty cooling option available which included the 1" radiator as an upgrade over the 5/8" one.  Now, if you still have the window sticker from when it was new, it will say if the vehicle has heavy duty cooling.  Otherwise, you have to make a choice.  If I lived in a hot climate, say Arizona, Florida, or South Texas, I would pay the extra money for the 1" radiator.  Any decent mechanic should be able to squeeze it in there.
