It is not unusual for a engine to work perfectly well and still have a head gasket problem, im a bit surprized that no one can find where the coolant is going, you say its leaking under the car but the garages still fail to find anything,

put in a bottle of K-SEAL. local motor factors will have it in stock... great stuff. also, is the coolant dropping on the drive inline with the water pump? and was the water pump gasket hylomared for insurance. Genuine water pumps on them only have a silicone bases sealant. this needs to be rubbed down and cleaned with emery cloth to ensure its clean... i have had that before. I take it it was not loosing coolant before the puimp was changed???
