1. Raise front of car so higher than rear.
2. Remove rad cap.
3. Heater: full blast, set to hot
4. fill with coolant.
5. run engine.
6. watch pretty bubbles pop and gurgle at radiator opening.
7. run for 15min at idle, top off as necesarry.
8. put cap on rad.

If your radiator does not have a cap like mine:

Look at the radiator where the upper hose connects to it... There should be a screw or **** there that you can loosen... Use that to let the air out.

I have also found that drilling a small hole into the thermostat can make things a bit easier.

I follow similar to what Jjcobm and Pele said. Sometimes squeezing the lower and upper radiator hoses with the filler cap off helps get bubbles out. Even if you don't get them the car should pull coolant in the system from the overflow bottle, so just make sure you keep an eye on it when you first drive it.

^ As your filling just squeeze the hoses to burp the system. It's always worked fine for me. No need for a 10 step process.

You could stick a t**d on that rad neck and Rob's car would make it look good.

You could jack the front up and leave the highest point cap off overnight...that also works.
