65mph for 15-20 minutes on level ground, no load, no tow, no hills.... after the truck is at operating temps.

Can you explain this post? I have used the VC9 at least 2, maybe 3 times and still have the original oil cooler.

once the cleaning chemical goes in, it begins to work immediately, not in a week or two and/or slowly. It's recommended to leave it in getting the most cleaning action from the application.. that same coolant is flowing through the oil cooler with the chemicals to loosen the debris and suspend it in the coolant so it can be carried away during the flush.
I'm saying that most every one of these threads about flushing and using chemicals ends in plugged coolers... be ready. You can flush with water and that may even result in suspended particles clogging the cooler, but mostly hearing that is not as big a gamble doing just water flushes.
I'd check the EOT/ECT differences BEFORE chemical flushing, you may not need it.

I haven't read a VC-9 bottle in a long time, but I recall it being really similar to the Restore+ label. At least the chemical is supposedly similar, so I wouldn't leave it in much longer than the hour that's in the Ford process:

Cummins Filtration says not to leave their cleaners in for longer than 3 hours, but you can run them at double the concentration level on the bottle.

I left water in the cooling system for the past 2 days without draining it. Should I be concerned as I will not be able to do the Restore flush for another week?
I know there is a lot of bad press about the VC-9. How about some good testimonials?

I have taken at least a week to complete my flush. I think you are okay as long as there is not any tap water mixed in.
