I just drained  and filled my coolant sytem using a Schwaben coolant refill/air purge tool.I was able to drain   about 5.5 gallons of coolant from the system.Once i reconnected all of the hoses I was only able to  hit about -13inHG on the purge tool.That number held steady for over five minutes, so I proceeded to refill the system,which only took a few minutes.I started the car and  there are no leaks,but  after about ten minutes of letting the car warm up and revving the engine with the pressure clip open the car slightly overheated( about 180 degrees) and heater is blowing cold air at the max setting.I'm assuming there is some air in the system , but I would appeciate any advice on how to proceed.
