I suspect your new radiator has a defective transmission fluid cooling
loop - assuming the transmission is an automatic. All too often, the coolant
also gets into the transmission and can cause real trouble if allowed to go
on long, so check the tranny dipstick for signs of milkiness. This won't be
something the mechanic did wrong, if that is indeed the problem. The failure
will be inside the radiator rather than in the way it was put in.

It's also possible the oil was contamination inside the new radiator,
though, and now has floated to the surface.

My understanding is that it is unlikely head gasket trouble will mix oil and
coolant in Honda engines, but I haven't had a head off yet to see for
myself.

We've seen a couple reports of oil in the radiator recently, but I don't
think anybody has reported back what the cause was. You can look at threads
from the last few months and see if there is a clue for you.
