Hello friends i am new at this forum, i am about to buy chevy volt 2014. i need your advice because i dont know much about volt. so my first question is what kind of antifreeze should i use on car? some says you have to use electric antifreeze some says all hybrid antifreeze are same. so i dont know which one to use. also please tell me is there any difference between 2011 and 2014 volt? is 50000 miles a big deal for this car? what is the best diagnostic tool for this car? where i can see a full battery life capacity? thanks a lot...
