If they do not have it on the shelves or behind the counter, a store associate can order it for you. Zerex G-05 has a service life of 5 years or 150,000 miles (250,000 km).
I have found that the Valvoline Zerex G-05 and the Motorcraft Premium Gold are the most cost effective choices vs the Mopar G-05 HOAT and the Mercedes Benz Antifreeze Agent.
Go with the Vavoline Zerex G-05, The HOAT formula is what was designed to be used with the cooling system. Available at NAPA, I did a flush on mine when i got a hole in my radiator make sure to use distilled water too.
You will need a lot more than what is needed to fill. Since you will drain all the coolant you can (some stays in the block) then run then drain and continue until you are stratified. I'll find the link that has a good write up for this.
Great link. Thanks. Now to my unusual problem. I had trouble draining the radiator with the drain . I ended up unscrewing it all the way. Now it will not thread back in. Fooled with it over an hour in the Fla sun (92 degrees). I have started pulling the radiator to better see what is wrong, of if something broke, the first step of replacing the whole radiator (ouch--for a 75 cent plastic part). any suggestions?
PS. Got my Zerex from O"reilly auto parts stores

Reason: Added source for HOAT
Got the Radiator out through the front: Did not want to fool with the fan. Found the problem to be a swelled rubber washer that seals the hole when closed. Had to lubricate it (Not all 11") and it then could be forced in far enough for the threads of the thumb screw to catch. Now that I have it off I might replace the belt and water pump since these are now real easy to get to.
I would change the fluid every 50,000 miles its not too expensive and keeps everything running right I should know my radiator fluid was supposedly good but it messed up my water pump and blew all over my engine along with my belt what a mess. Just because its good for 100,000 miles doesnt mean it will work its best with 100,000... If you dont wanna take it from me take it from the ford 6.0
