You may have some air in the cooling system. To bleed the system take the radiator cap off and turn the heat temperature all the way hot. Then start the car and let it get to operating temperature and then top off the coolant in the radiator and the reservoir. Then replace the cap and take for a test drive. If this does not work jack up the car in the rear while the heater and engine run.
