did I do It right
well today I attempted to drain and refill the coolant system. I first drained the radiator then filled it with water until it ran clear. Then i disconnected the hose that goes from the throttle body i don't know what its called and began to fill the raidiator with prestone dexcool 50/50 premix. Then i noticed coolant coming out of the hose and connected it back and resumed filling the radiator. So did i do it right because on the airlid it says that it requires a special fill procedure. Also it only took 1 jug and a quarter to fill the rad is that normal since i taught it would take more. Thanks

It's difficult to get the entire system to drain out using that method. However it's better to do it that way rather than not at all.
I have a machine at work that uses vacuum to suck everything out of the cooling system once the thermostat opens up. It then injects the new coolant back in afterwards-pretty slick. That's the only method I've seen that did this in such an efficient and fast way.
I would just check the antifreeze freeze level (you can get a cheap and accurate checker at AZ for a couple bucks) and make sure that's ok-then let it go. Do it again based on time and mileage when it's necessary and you will be doing better than most people.

Yes you need to check the strength of your antifreeze. Since you drained and filled it with 50/50 after purging the rad. with water. Especially since you are in Canada. If it is only good down to 0 F, drain and fill again with full strength. Also, you can be sure you have all the air pockets gone when you check the overflow and the level there stays the same after a few hot/cold engine cycles.

Yeah. If he has a low freezing point, you must drain the radiator and then fill it with full strength. That will help the weak (too much H2O) solution that might be there right now. He said he flushed his radiator with water then filled with the 50/50. If the coolant is only good to negative 10 or so now farenheight, he needs to drain the radiator and fill with a gallon of full strength then top off with 50/50.
Like I said, check what the strength is now before doing anything.

i went out and bought a antfrezze tester but i'm not sure how to read it it seems the big arrow rises to the top is that normal.

It has 2 arrows? A small one on the top to show you if you are holding the tester level. That should be straight up. The tester should be almost full, sometimes they have a fill to line when you take a sample. Then the big arrow (this one is the horizontal one, eh) will show the antifreeze strength when it is filled with the right amount of coolant. If it is pointing straight up, all the testers I have used means that you have a lot more coolant than water. As long as you don't have more than 70% coolant you should be ok. It is not good to run 100% coolant, it won't transfer heat effectively and the freezing point is only like -10F.
