thanks for this..mine just failed at 167k time to order up a new radswapping out the radiator can be done in as little as an hour. There are some tricks that will help.
Remove the skid plate and drain the radiator, while it is draining, on the new radiator, take off the passenger's side plastic mounting piece.
back to the truck, disconnect the hoses. disconnect the trans cooler lines.
take out the screws/nuts that hold the fan shroud. remove the passenger's side radiator mount bolts from the radiator. leave the mount in place.
on the driver's side, use the holes in the grill to remove the radiator mount bolts (leave this piece on the radiator)

From below, slide the radiator up. Once it is about half way out, you can pull it out from the top. having an assistant at this point will help greatly.
slide in the new radiator and reconnect in opposite order.
