Picked up a radiator while on my cross country trip (in Indiana) just to be safe. Ended up not needing it (and the fit would've been off anyway) but Napa stores in NY will not take it back. I put it in the for sale section but here's the link

Napa corporate got back to me and gave me a store where i can return it. I'll probably just try to exchange it because i still need the radiator anyway and it's technically already paid for. Can anyone tell me what the difference between "standard cooling" and "heavy duty cooling"? i think i've found my size radiator w/ engine oil cooler but it says standard cooling.

I would always go for Heavy duty in a van, they probably want to know if Air conditioning is involved that requires a heavy duty radiator. or at least a little more. but with vans pushing more air and with a high top or more Flares and spoiler and the engine is contained in a little close fit box Heavy duty never hurts
