Possible trapped air pocket. Set to full heat position, lowest fan speed, remove rad. cap, start engine and let idle for 10 minutes, then hold gas pedal at 1500rpm for two minutes then let idle for two minutes. Shut engine off , let cool for 30 minutes. Top up coolant level and reinstall cap. Drive vehicle, should get heat now.
