Coolant change

I just did mine and it is easy. When everything is cool disconnect the lower radiator hose and drain into a container. I use the mortar tub you can get at Home Depot. It allows for splash. Fill it back up with distilled water and run it for a while. Drain and repeat four times. The coolant capacity is 27 quarts so get five containers of the Ford Premium Gold antifreeze. Don't use anything else! Put in 18 quarts and fill the remaining capacity with distilled water. I think you'll find a lot of sand and mud in the coolant. I did and put in a coolant filter shortly afterward.

I got it from the dealer. $21/container. This being the delicate diesel that it is I wouldn't use anything else. You'll also use about 10 gallons of distilled water if you do the complete flush.

You don't need 5 gallons of coolant, capacity is 7 gallons and you mix it 50/50 with distilled water. You also don't need to flush it 4 times, maybe twice. After the last drain, add 3 gallons coolant, then 3 gallons distilled water, then add another gallon of mix after running it to work it all into the system.

Crap. My math is bad. 1/2 of 27 quarts is 13 quarts so three gallons is right and that is what I used fortunately.

Some people say it only took them 2-3 times others say 5-7. I don't really think there is a set number just make sure your getting the thermostat open between drains and that its only water coming out in the end.
