When I did mine, I just jacked up the driver side of the car a little bit and ran the car till it warmed up, then let it cool off. I repeated that 3 times, kept the coolant topped off and no problems since.

I didn't even do that. Just let the car sit level, opened the reservoir and let the engine warm up. Then I revved the engine to about 3K several times and held it for about 30 seconds each time then topped off the system if required.

Continue to do this until air bubbles stop coming to the surface of the reservoir. This procedure is in the service manual.

You can do it a few more times if you wanted to as well; put the cap back on, drive it and get it nice and hot, then let it cool down all the way and repeat.
The more times, the merrier, air in a cooling system is not a good thing.
If you do many repairs on your car (or any car for that matter) it may be worth buying a coolant vacuum filler for $100-200, similar to this one:
We use one like it, it works great and only takes a few minutes to fill the system with no air bubbles.
Feel free to call, email, or PM us anytime!
Thanks!

I worked at an Autozone for awhile ,no we did not have one to rent or borrow. If you have a mightyvac you may be able to use that. It only has a 4oz container though.The mightyvac can also be used for testing, spark advancer, any vacuum operated device, bleed brakes,etc. The JDP tool was not that costly of a tool.

I cut the bottom out of a 2 liter bottle of coke, I placed the neck into the coolant bottle and filled the bottle 1/2 way. start the engine and let it come up to temp, when the t-stat opens the coolant will be sucked down as the air is released.
