Radiator Coolant Leak near Petcock

[buickman104]

Got the low coolant light. Noticed a wet spot near the petcock. Hooked up my coolant leak tester and pressurized the system to 15 PSI. Recorded this video while the system was pressurized.

For people with similar experiences does it seem like the leak could be resolved with just a new Petcock? or does it seem like I need a new radiator? It is hard to tell if it is leaking from the end tank or just the petcock.It is not audible in the video but there is a strong hissing sound when pressurized.

Radiator looks original and car has 217,000 Miles.

try the blind camera man trick lol stick your phone down in front of that area and see where its bubbling from.

its wet there, but the tank could also be cracked.
