07 S80 Coolant leak

Hello folks. I have a 2007 S80 3.2 thats been leaking coolant. Started off pretty slow at first, couldnt even tell where it came from. Today i noticed white spots on the upper radiator hose where it connects to the radiator. Looked around a little more and looks like its been spraying either from that connection or somewhere under it because there were more white spots in that general area below the radiator/hose connection. I filled her with coolant, drove around til she warmed up and pulled over to take a look and of course i see some liquid on the ground, skid plate, and the bottom edge of the radiator. Over the course of a day it will go from the Max line to about half an inch below Min. Seems to be coming from the previously mentioned connection. Any ideas? Is it the hose or the radiator? Maybe something else? Volvo wants almost $200 just to pressure test and i cant afford that. Any suggestions would be welcome. Thanks guys.

Could be a deteriorating hose, loose or broken hose clamp a cracked neck on the radiator.
Sometimes as hoses age, the clamp can cut into the deteriorating rubber hose causing a leak.
Good luck with your repair.
I will be in Katy next weekend.
PM me if you need a hand finding the cause.
