A radiator shop has tools to repair this problem maybe without removing the radiator, copper is a soft metal and with heat can be molded easily. I dont think it will cost much since it is a simple job. You can try it yourself with a blunt chisel or big blunted screwdriver with a soft hammer try pushing the ridge out from the inside and be sure in the future to place the hose clamp behind the ridge so as not to squash it.
a hole in the radiator
You replace the radiator

If the hoses are all tight, Then the radiator must be leaking. REPLACE RADIATOR
The coolant leaks out.
Effectually, no.
First You Would find the drain plug on the left or right of the bottom of the radiator,locate the plug screw the plug out let the fluid drain put the plug back,go to a local parts store get 1 gal. of antifreeze pour that in first, then fill the rest of the radiator with water/check for leaks,no leaks your set for life.
Same color as what?
Over-obvious answer? Your radiator, or one of your radiator hoses, leaks - badly.
oil leaks
Some have an internal transmission cooler & extra small internal radiator for that purpose.
Probably a radiator leak or a split radiator hose.Check coolant levels in the radiator.
