Depends on how long the coolant has been in there and if it is due for a
flush and fill. If not, and the two quarts is clean, add it back, but into
the pressure tank, not the overflow, and do a proper bleed.
Yes, the system is self-bleeding, but that's a lot of coolant replaced by
air. Why chance it?
