What type of coolant do they put into the 6.4 from the factory?

???

I don't wanna mix different coolants in or antifreeze just incase this **** needs to be special for special vehicles.

It is ford gold or Zerex G05 only, plus distilled water. Anything else and the system will have to flushed and refilled. You can get the gold from a dealer and the Zerex from some auto parts stores. Just call around to find a supplier.

I just read it the other day. If I remember correctly it's 6 years or 120k miles.

Normal conditions initial 100,000 miles and subsequent changes at 50,000 miles, check nitrate strength 20,000 miles or 800 hours. Check concentration strength every 6 months.

Special conditions change every 60,000 or 2400 hours, check nitrate and concentration strength every 20,000 miles or 800 hours.


Special conditions are extensive towing, long idle time (check hours), extended low speed driving, biodiesel use, or off road / dusty conditions.

That damn Biodiesel; it gets into everything! I have to change the air in my tyres every 10,000k. Not to mention the washer fluid - run that wretched Bio and the windscreen washers leave streaks on the glass!

LOL

I believe the biodiesel use would only pertain to oil and filter and fuel filter but they do not break it down that way.
