Yes you do, there are a lot of steps to this job, too much to post in this little box.
My "book" says:
"Remove the right headlamp assembly, the grille panel, the right cowl grille support panel, and the right radiator core support assembly."
I would suggest that you subscribe to ALL DATA DIY
for $26 bucks for the year. They give you step by step instructions on this job, and you can also use the subscription for any other job on your van throughout the year.
Or you could find an actual factory repair manual, perhaps on eBay.
