This is how I do mine (old school with no fancy tools):
1. Open the rad cap and see if you need to add coolant
2. If you add coolant, pour it very slow not to trap air in the rad top fins
3. Leave the cap open and then crank the engine for 5 seconds then turn it off
4. Go back and fill it again very slowly, then crank it for another 5 seconds and turn off the engine again
5. Repeat this process up until there is no more bubble coming out, until the coolant is top up to the fill rim
6. Put the cap back tight, then fill the reservoir to full, and then start the engine again, this time for longer time
7. While the engine is running, turn the heater on to max full blast high-heat, keep an eye for the temp gage as it goes up to the highest heat register
8. When the gauge is already very hot, turn the engine off, and listen for any gurgle on the engine. Let it cool down for an hour or so, then go back and open the rad cap, inspect if it needs more coolant fill
9. Repeat the process starting from #2 through #6. Before you do # 7 go and drive on the street and around the block at a full blast high-heat. This process is to shake and rock your engine while you brake and turn corners, the thermostat triggers the pump to flow more coolant into the system as the air trapped inside flows out to the rad.
As soon as you get home, go to #8, and #9 and do it all over again if you need to (engine gurgle is a sign of trapped air in there). Sorry for the long blah-blah-blah but this is my procedure.
