throw the car over your shoulder and pat it on the bonett...
open the filler cap(next to the alternator, not on the AST), get a bottle of mixed coolant ready, start the car with the cap off and let it idle. top off the coolant as the leve drops until it stays full. replace the cap.
Burping the system can be time consuming. Be patient, and be sure to keep checking your coolant level before you take it for a drive, adding as nessecary.

I would be worried about the part "i cant restart the car right after, i have to let it cool down cause it wont start."
That tells me something is causing low compression when you are heating up, whether its getting extremely hot, or maybe the OMP isn't doing its job. Maybe add some premix to the tank and see if anything changes.
The boiling sounds are not supposed to be present on a properly function cooling system. There is too much air in it, maybe burping will resolve it, maybe you have a pinhole leak in a coolant line or in one of the caps. Do you ever get a faint coolant odor? Also, maybe your coolant/water mixture is too low on coolant, too high a % of water will boil at a lower temp.

How cold does it get in the wintertime where you live?
Probably go with 50/50 to be safe, in warmer weather you can use 70 water/30 coolant.
Also, be careful when burping the coolant system of air......only remove the cap when the car is cooled down, or you risk getting burned.
To speed up the process, leave the coolant hose off that goes to the back of the throttle body while the car idles, watch it closely and slide it back on the nipple as soon as you see coolant start to come out.

Do you have an upgraded Aluminum AST or stock one? If an aluminum AST just pull up the lever and turn it left until it comes off.
