What type of antifreeze does the 2011 ford fusion use?

The 2011 Ford Fusion is said to require Peak OET engine coolant, PAG0B3. With that said, it's really not a picky car whatsoever; many drivers report using all types of engine coolant, with mostly positive levels of success. However, the most important thing is that You don't mix different coolant types; doing so can lead to adverse reactions, which can turn Your anti-freeze into a jello-like substance. If You're unsure of what type of engine coolant You have in there (for instance, if You bought the car preowned), You may be better off draining the fluid out of the radiator and replacing it with all new coolant. Solutions like Dex-Cool had be had quite inexpensively, so a coolant flush won't run You too much money.
