I flushed my radiator and just let the engine run with the cap off until it got too hot and let the air bubble out, when it gets hot turn it off and let it cool down and do it again until it stops bubbling out.

I did a slow fill, about 1/2 quart at a time over the course of about 2 hours as I was working on other things. I also rocked and bounced the car on its suspension to help any air pockets dissipate.

There's a drain plug on the passenger side of the radiator. There's also a drain plug on block as well, can't remember where it's at, it's a Haynes manual though.

Just fill it up, start the car with the cap off. Add coolant as necessary, it should burp itself.
