It really should self bleed, but if it is a problem with air trapped in the heater, try and elevate the front of the car so the coolant filler is at the highest point, run the engine with the heater on high, air should make its way out as the system heats up, with the car at normal temp both heater hoses at the fire wall should be hot to touch.
