Coolant Change

[F250power6]

How often do you change coolant? How often do you need to change fuel filters?

[michaelaiman]

Depends what coolant you are using. Fuel filters must be changed at 15,000 miles using only FoMoCo

^^ that is correct^^ many of us go 10K and if you are using the Ford Gold coolant I would not go any further then 25,000 miles or 2 years (whichever comes first).

Also a coolant filter is money very well spent to keep the cooling system from plugging up the oil cooler.

ELC you can comfortably go 5 years with it, if you are severe duty: pulling heavy on regular bassis you may want to do it sooner.

And if you are running Ford's Gold, make sure your adding SCA's

What is SCA's?

[michaelaiman]

SCA: Supplemental coolant additives. For a diesel, these are needed to combat cavitation. Diesel rated coolants come pre-charged with SCA's. cavitation is formation of microscopic air bubbles in the cooling system which can, believe it or not, eat the block itself. Friend of a friend was running regular green in his 7.3 and it ate a hole in one of his cylinder walls. Just the nature of the beast

Thank you. I add Kool Aide to my yellow coolant.
