Did the work involve opening the cooling system? It's possible it's not bled properly.
I would start by starting the engine cold, removing the cap, and pouring in coolant mix with the engine idling until the reservoir stays full to the line. Then put the cap back on and shut off the engine. My guess is you'll find it doesn't overflow, and that you've purged out an air pocket. (I say to do this with the engine cold because you should never add cold coolant to a hot engine.)
