water leak
from the firewall, it would almost certainly have to be a heater core or one of the hoses feeding the heater core. Have put a few cores in these Volvos, usually in the sleeper, though.

It is only going to get worse. I would turn off the water valves and get it fixed asap. it might seep for months or it might blow the heater core apart in 15 miles. The engine protection features should shut the engine down before the water gets critically low, but this problem is certainly not going to get better by itself, only worse.

When I had my 780 it turned out that the coolant leak that I had was a valve that is on the right side of the heater core. It had gone bad and was a slow leak. Just a thought.
