LOSING COOLANT

I have a 98 Escort ZX2 that keeps losing coolant out the reservoir. The car was cold at 5:00pm yesterday with the radiator full and the reservoir empty.  I filled the reservoir to ''full when cold'' and drove for an hour.  The radiator was still full when hot but the reservoir had lost 1/2 the coolant I put in there.  Again at 6:00am, the car was cold, the radiator is still full where it was prior and the reservoir is now 3/4 empty from the cold line.  There does not appear to be a hole in the reservoir.  Does anyone have any idea what would cause this to happen?

pressure test system. check for leaks. possible head gasket leak.

  First do you see any murky white beige color sludge in the oil dip stick???  If you have this you have a Head Gasket leak...or ....Head gasket crack...Block crack...etc....
 
Is there any Anti freeze leaks on the ground...driveway...etc???  Check the Radiator for leaks....
