W124 Leaking radiator
 

I was wondering if anyone has had the same kind of leak from their radiator as me. Symptoms are noticeable coolant loss after a fairly long trip, no leaks at any hose points or from the expansion tank, but a tiny drip from the bottom right corner (as you look at the car from the front).
It doesn't seem to leak during driving, but when cooling down.
I'm pretty sure the radiator is original so 10+ years old now.

As you may have read the upper plastic hose connection on these radiators become brittle and break off. Look closely for white residue below the upper hose connection ... which will indicate that it's leaking. You might want to carefully remove the upper hose and inspect the plastic connector for cracks. I suspect that you'll be buying a new radiator soon. Be sure to buy a Behr ... OEM.

thanks for the reply. I have already checked all the hose connections and surrounding ares, there is no white stuff suggesting a leak there. I also have the metal re-inforced neck version of the radiator.
