I had a similar problem. It eventually turned into a head gaskets issue.

The original overheat was definitely crud in the air side of the radiator.

As kennedy suggested... Take the shroud off the cooling stack... Pull the stack if you're not sure.

Don't mess with it, take the hit and pull the radiator... Powerwash the air side.

I tried delaying it and I think that contributed to a very, very large repair bill.
