Engine/Radiator back flush in 6.0 liter diesel

[len741]

My 2006 Ford F-350 6.0 liter diesel dually(purchased new) has 58K original miles on it. The maintenance guide says to flush the engine and radiator at 5 years or 60K, whichever comes first. In the absence of any leaks or problems, is this necessary? Thanks in advance for your advice.

YES. You DEFINITELY need to keep it flushed regularly if it has Ford Gold coolant in it.
btw
Go do a lot LOT of reading about the oil coolers clogging. Then you'll understand.

You will get TONS of answers and most will vary with personal opinion.

-Flushing could loosen some particles which could eventually clog your EGR cooler and/or oil cooler causing damage.
-Flushing could remove the particles which could eventually clog your EGR cooler and/or oil cooler to prevent damage.
-Flushing would give you the opportunity to ditch the Ford coolant and switch over to an ELC.

Do you already have an EGR cooler delete kit or a coolant filter installed on your truck?

My theory is that if you flush it often enough and get fresh coolant in there, then you don't have the old stuff breaking down and clogging the passages.

I agree with you. I wasn't second guessing your post, just giving the OP a heads up that he will get a wide variety of answers on this topic.
I personally, flush often and still use Ford gold because I can get it inexpensively from a Ford dealership.

All of that information you quote is out of date.
Ford has a TSB for cooling system maintenance (number 09-8-5) that details the updated requirements.
