As recommended in the end of the tech article, I would bleed the system first by using the bleed screw at the front of the radiator on the driver's side and then do this. Your heater core holds about 24-36 oz of coolant and the rest is in the engine and the radiator. The water rushing out is typical because even though the car is cold, I hope, it is still under some pressure and its looking to get out either into the reservoir or the open hose. If you dont have heat after this, its probably your thermostat. I found that the easiest way to check this is by warming up your car, drive to the closest highway or high speed street where you can go abouve 50mph. If when you start getting on the highway you see that the temperature guage is lowering and when you are on the highway its still low but when you get off and stop for about 1-2 minutes it start to get up to the normal level, its most likely your thermostat. The water circulates faster through the system at higher speeds because the water pump is controled by the timing belt. If the thermostat is always open, water passes through the radiator to cool before it goes back into the cooling system. If the thermostat is closed, that means the water is below the 180 degrees and is keeping your engine cool. So, the thermostat should open when your car's water temp is above 180F and close when your car is cold. After the thermostat change you should see that the temperature stays the same on the local roads and the highway. Hope this helps. It a PITA to change the thermostat but well worth it. Good luck.
