Dirty coolant

I have a 03 F250 6.0. I just had the oil cooler and EGR cooler replaced last summer (about 20K miles ago). I've been keeping an eye on my coolant since then.

Well, long story short, I was working on my truck this weekend and had to remove the intake hose off the top of the radiator. I collected some of that fluid and its what I would call dirty. Dark brown in color, with what looks like small particulates floating in there (carbon maybe?). I'm unsure as to what could cause this discoloration and could use some help. I do not think it is oil in the coolant; I would assume they would separate after awhile and be fairly obvious.

Any thoughts would be appreciated. Thanks in advance.

That is very likely the coolant reacting with the block heater element.International has a fix Ford do not,the fix is a coolant filter.

Thanks for that heads up. Searched a bit more on this site and found the international fix you were talking about.

Didn't think about the block heater element. Been using that all winter.

if you install a coolant filter, your coolant will look as good as new in a couple thousand miles. Look at the coolant filter offered by dieselsite.com as that's what many people are using with great results.
