Added the wrong coolant to the 6.4

[hurdler]

I bought a used 2008 F250 6.4. It has 15,000 miles on it. It is missing the owners manual. I went to Auto Zone and was told that the yellow Prestone coolant will mix with anything. I was checking all my fluids and noticed the coolant was about 1/4 of a gallon low, so I topped off the holding tank, don't know the name of it. I learned at powerstroke help.com, to never add prestone to the mix. I need to know if that little bit of coolant will hurt anything. It was my mistake for not doing all my homework. By the way, It is a XLT, Shadow Grey, 6inch Super lift, Toyo 37 inch open country tires, on Incubus Chrome wheels, plus the Ford Premium care 7 year 100,000 mile warranty,out the door for $36,500. Was that a good buy. Ford signed off on the lift, said it was professionally installed, does not void any of the warranty. crew cab , long bed.

If it says on the jug "will mix with all types" and you only put 1/4 of a gallon in it, I wouldn't lose a whole bunch of sleep over it. Save the receipt, in case there is any sort of problem down the road -- it will show that it's a mix-all coolant.

Hope this helps

From now on, Ford Premium Gold only. CXC-7-B I think is the part number (but that may be a Canadian part number, US may be different -- will have to go look at my owner's manual, but it's out in the truck.)

thats is what i hoped. i saw on powerstroke help.com, that the coolant i used wil turn to jello and clogg things up due to the high heat.
