Coolant Leak

Hi Guys
I am losing a little coolant every few weeks I get the low coolant message, I see on the drivers side where the rad pipe is connected is wet, could the clamp be loose or are these rads known to leak from this area.
Any info appreciated

IIRC there is a ring inside that shrinks over time and allows leaking. The rings should be fine but wouldn't hurt to replace if you can find it. I am having this same issue.

Mine looks like its leaking from where the air intake pipe is attached to the rad, there a hairline crack and coolant is dropping onto the pipe, I'm going to try some JB Weld.
Has anyone heard of Benco brand of radiators.
