2013 RX350
85,000 miles.
It has an external head gasket leak in the valley under the lower intake. Lots of pink coolant crusties in there.
After research I put Subaru coolant conditioner in the radiator and the leak has 100% stopped for now.
How urgent is it to fix this properly?

"Subaru coolant conditioner" is a stop-leak product similar to Bar's Leaks. I'd get it fixed properly before you wind up with an internal head gasket leak and engine damage.
