just bought a 2006 f350 and i noticed it had green antifreeze in it. is this a major no no or will it be ok?
If that antifreeze is conventional green, or Ford Gold tinted green, or any other silicate-containing antifreeze, then one of two things will happen:
1. You do an EGR delete and are fine forever; or
2. Your oil cooler will periodically clog with silicate gel, causing a cascade of secondary problems.
The EGR cooler runs too hot for silicate anti-freeze; this is one of the critical design flaws of the 6.0. Unfortunately, admitting this would instantly bankrupt Ford. In order to keep the tens of billions of repair costs firmly on the customer's shoulders, Ford cannot admit this problem, and so your Ford dealer must tell you to use the factory Ford Gold coolant.
I disagree - The Ford Gold works just fine in MANY MANY trucks. It is a low silicate formula and the silicate content is very small. With proper maintenance, snowseekers experience (see post above - 180k miles and no problems) is the norm assuming proper maintenance and operational practices. That being said, the diesel rated ELC coolants (non dexcool) do seem to be more robust (ie do not require flushing at 50k miles) and are a good choice.
His degas bottle cracked, he bought a new one, and refilled with the green stuff thinking it was ok to use. A clogged oil cooler later, he regretfully sold his truck and now drives a Chevrolet.
Flush and refill with an ELC Shell, CAT, and I believe Chevron makes the ones commonly used. They're all Red in color and make sure to get the concentrate version and not the 50/50 premix.
A diesel site coolant filter would a good added layer of protection.

I'm sure a lot of people get away with having low or high levels of silicates in their cooling system. But that's not a roulette wheel I feel like spinning... I've already got stupidly large amounts of money and time invested in these engines.
The way I see it -- no amount of regular maintenance can prevent the EGR cooler from cooking the silicate coolant into gel, or prevent the gel from clogging the oil cooler, etc. It may hit you, it may not hit you, it's random chance, and that makes me crazy.
That said, I am glad to hear your 6.0 is well, and I hope it stays that way forever.
