Afternoon all Knowing nothing about cars whatsoever, can anyone advise if there is a particular type of antifreeze I should be using in a 15 year old Nova? All I can find in the manual mentions GME L6 368 as a standard, but I am struggling to find what this relates to. They advise AC Delco Universal Antifreeze, but I can't find this either. Any advice welcomed. Cheers Drex
