Which radiator do i need?
I performed a VIN lookup and it says no tow package.
Denso offers the following

I measured my actual radiator and the core dimensions are closer to 20 inches tall, 26 inches wide. So which one is it?

The specs have reversed width and height so they’re about the same size. Only core thickness and radiator outlet diameter different. Compare with yours. I would think there’s no problem fitting a tow package radiator in a non tow package van. For that matter, a non tow package radiator in a tow package van if you don’t tow heavy loads long distances or uphill. At most you’ll need a different lower radiator hose.

Another telltale is the tow package driver side radiator fan has 6 blades. Non tow package driver side fan has 5 blades.
