I just looked up a new radiator and there is a great deal on Amazon right now. AcDelco 21688 for $125 delivered. They are showing there is only 1 left in stock and if I was you I would jump on it and buy it.

Has anyone tried something like this as a stopgap to clean the radiator?

I would not waste the time with that. You are going to have bugs and all kinds of other things packed in the 4 layers that stuff is not going to touch.

I was thinking of making a wand and spraying it between and deep into the stack.

The closest shop that can do the work is 2 hours from me so this is becoming a real PITA.

What I would do if you are in a bind is to super soak the stack in a product like Simplegreen or degreaser and spray it out. re-soak it with the product and spray it out. keep repeating this as much as you can and keep a visual on the progress till you can get it clean.
Be careful not to damage any of the cooling fins in the process

The radiator itself is not the only place in the stack that needs to be cleaned, it ALL needs to be cleaned, right? If the radiator is perfectly clean but the intercooler is jammed up with who knows what, you aren't going to get the cooling you need. Clean it all. I used a similar product specifically intended for air conditioning units for a house and found it helpful, perhaps no more than Simple Green or other similar products, but definitely helpful. My stack was pretty clean when I used it.

How did you get it in there? I'm thinking one of those bug sprayer things so I can get the wand between all the pieces.

Removing the fan shroud on trucks is easy as compared to vans. When working on the van and you are that far in you do a bunch of work to save from having future headaches. If you do the job right the first time you should be set for at least a couple of years depending on how much you drive and the conditions.
