Does this look like a radiator leak?

This is a new ORM radiator. I can’t say for sure that the spot in the photo wasn’t there from the beginning but I old the notice if so. I have only run the engine for maybe a total of an hour since radiator install. It’s consumed a little coolant measured by the drop in overflow tank level but I think most of not all of that is just burping out air. I’ll keep watching.

I’ve probed the spot with paper towel and don’t get any evidence of moisture.

Isn't that the AC condenser?

Hose it off with brake clean, let dry, see if the spot returns.

Ahh. Never mind....

Brake clean advice is good. If it’s just a particularly greasy bug splat it’ll stay gone. If somehow a pinhole AC leak, it’ll come back.
