How Much Coolant?
Since there are so many variables - year of car, engine size, etc. it is best to refer to the Owners Manual for your specific car to determine cooling system refill capacity.

If you are environmentally concerned then you need to take it to a repair shop that has a flushing machine. If not, any parts house has the chemicals. Just follow the directions on the container.
Purchase a Prestone flush kit, a container of radiator flush, and new antifreeze at a automotive parts store. There are directions on the flush kit package. What you will be doing is adding the chemical to your cooling sytem then inserting a flush tee into a heater hose and back flushing the system using your garden hose. Works very good.
To let the coolant out:
First, take off the black plastic guard underneath the front of the car. It's being held in place by a bunch of small screws.
After removing the plastic cover, you should be able to see the radiator, and at the bottom corner of the radiator on driver's side, you'll see a white plug/nut. I used a 19mm key for that.
The plastic screw does not come completely off, just unscrews far enough to let all the coolant out.
To let all the coolant out, your engine should be cool. Take the top off the coolant reservoir, place a bucket under the car and unscrew that white plug.
At this point, either fill it back up with coolant or follow the directions on the bottle of coolant flush you bought.
The easiest stress free way is to go to Wal-Mart and get a Flush Kit that hooks up to your garden hose.
Buy a flushing kit at Wal-Mart or auto parts store comes with instructions, fitting, and adaptors.
back flushing is old country... if she's plugged replace her.
There is a small white plug underneath the radiator. If you're looking at the car from the front, it's on the right. Unscrew it (hopefully you do it when its cold) and let it drain. From there, you put a hose in the reservoir and let it run through the system for a few minutes, keeping the white plug off. Then shut off the hose, put the white cap back on, and put in the right quantity of regular antifreeze.
Be prepared to bleed trapped air from the car's cabin heater system - you'll know you need to do that if the car's heater fan doesn't blow hot air after the engine has reached its normal running temperature!
