Coolant spray

Hey folks, need some help/advice. Just installed a 3 row aluminum radiator on the Stang (66 w/68 302). Took her for a drive and she runs way cooler, good thing, however, there is white spots all over the right side of the engine. Pretty sure it’s coolant, I started her today and let her idle/warm up till the fan kicked on and saw zero leaks/felt no moisture. Could the fan zip ties/temp probe have caused a leak that I can’t see? Any help is greatly appreciated!

It may have caused a very light leak ,i am not sure why the spots would be white though . I would wipe it down real good and run it again to see if it shows up again .
Was there any chance of coolant getting spilled in the fins ,it may just be blowing out

Thanks, there was some coolant that was spilt, maybe that’s it. I’ll get her cleaned up and run it again. We shall see. Thanks!
