Could also be a split t-stat gasket. Look for coolant stains around there.

If you're losing that much coolant, that quickly, to completely drain the reservoir every few days.....that's quite a leak!

If I jack in up and get underneath will I be able to see it from under the car?
Thanks.

Have you tried pressuring the system. Many big name auto parts stores have loaner pumps. With engine off. pump at overflow tank to abt 8 to 10LBS and see where it is leaking from.

Cylinder leak down test and a dye test goes a long way for finding cooling system leakages regarding volvo's.

For a pressurized system, it's quick to 'push' out, unlike an open/non-pressurized system.
