Hey guys very appreciative of all my answered questions lately, however need some tips and tricks to troubleshoot a leak.

Leak is on driver's side and to me looks as if the leak is from one of hoses connected to that side radiator. I can't really tell if it's coolant or power steering fluid.

I have replaced the top radiator hose however I used the same original MB clamp which I am going to change. I have also replaced the hose that goes to power steering pump. I have the hose that goes from radiator to rack but haven't changed that yet.
Still leaking same location after some of the fixes.
Any tips I can try to definitely find the leak?
Could it be the metal nipple from radiator that the hoses attach to? I have never seen that happen but possible?

Thanks

Color of the fluid leaking out to the ground?
Coolant vs. PS fluid color is different.

Hard to tell. Ground is wet in morning. Doesn't smell like coolant that I am used to smelling with non German cars. You know that kinda sweet smell of coolant

Put some UV dye into the coolant only.
Get yourself blacklight flashlight (good to have too in your arsenal of tools, to find ac leaks)
Monitor.

That lower PS cooler hose was subject to several service campaigns. High pressure screw type clamp is only thing to use on both hoses.
Wrap clean paper towel around affected area in the evening and look at it in the morning.

Update.

I replaced the upper coolant hose clamp from the original MB to a new one and also the upper ps hose to pump. Placed cardboard piece under each hose going to radiator and no leaks for past three days. Now today noticed PS fluid dripping from torsion bar. I believe the lower ps hose runs above that bar going to rack. I will be changing that hose tomorrow with a new one from FCP Euro.
Will update after hose is replaced.
