Under the van are the 2 long heater hoses running right next to the 2
long main coolant pipes.
Figure out which of the 2 hoses warms up first.
Cut it in a accessible spot and add a valve with the lever facing where
you can best reach it.
An autoparts store should carry heater valves with the right hose diameter.
Dennis says 5/8" and I think some later vans may be 3/4".
This is the inside hose diameter.

Clamp the hose pinched shut on either side of where you are going to cut
it to reduce coolant loss.
Or work quickly and expect coolant dripping down your arm.
