Antifreeze
My PSD came with the gold antifreeze that's supposed to be good for a gazillion miles. While having the oil changed the other day and being distracted from what the greasemonkeys were doing by some clown that was a self-proclaimed diesel expert, I saw them topping off my antifreeze with the plain old green stuff. It was done before I could stop them.
Anybody know if this is a problem?

I wouldn't lose any sleep over it. It really depends how much. Remember that your cooling system holds 7+ gallons of coolant. It causes the gold coolant to take on the characteristics of the green. Not anything desirable, but damage has already been done apparently. If you mix the green with the Dexcool, straight OAT coolant, gummy bears can form from the reaction, causing clogging of radiator passages. But I have not read of anything like that when mixing green with the gold HOAT coolant.
I had decided that I was going to make a label on my degas tank advising that the coolant had been changed out on mine, whenever I change over. But then again, this is another reason why I don't let anyone touch mine.

I would have your coolant changed out immediately and have those monkeys replace it at their own expense. Right now you basically have plain old antifreeze without any anticavitation properties. You could go down to the dealer and get test strips and test the coolant and add the required amount of anticavitation additive and settle with green coolant with the hassle of regular testing and additives. If the monkeys don't believe you have the call a ford dealer who knows what they are talking about. That's why I don't let them touch my truck.

Ford has a guideline on this and a few cups of green does not affect the gold, at some point the coolant has to be treated as a conventional but nowhere does it say that topping it up with conventional destroys all protection. It doesn't work like that.

that has some beneficial information to the original thread poster that received the little amount of green on top of the gold. Since the gold is a HOAT coolant ( Hybrid Organic Acid Technology ) I have no doubt he will NOT have damaged his gold coolant. Just fractionally reduced the long term effect of the gold corrosion protection.
And perhaps it can benefit you, too.

Thanks for the comments, folks. Haven't noticed any foaming, gelling, or any other irregularities in the overflow tank, so I guess all is OK except that it looks like a beer with a drop or two of green food coloring in it.
Since I'm about 4K miles away from "my" service interval at 50K, I'll probably leave it alone until then and change it back to all gold. I just don't think I can stand not knowing whether or not everthing's right.

Motoxman mentioned Evans coolant and I have been wondering if anyone has any definate proof that it is not good in PSDs. I read the TSB from Ford on it and see they recommend you not use it. I brought the coolant up in a (https://www.ford-trucks.com/forums/showthread.php?t=244000&highlight=evans) thread earlier this year but it kinda fizzled out on me without any definitive action. I would go for it if I knew that I wouldnt be needing to replace my seals and hoses in a year. Anyone have anything to add?

Then click color and its signifigance. The link posted by tjc1989 didn't say anything about the two coolants and compatibility so I don't know where you guys get the idea they are compatible. Read carefully why manufacturers color their coolants, then figure out why green tinged coolant may cost you several thousand dollars when an engine component fails, and then blame you for not following instructions. I don't know about you guys, but I'm not looking to replace an engine block because I'm too cheap to spend $25 on the proper coolant to keep my warrantee intact.

OK, to begin with I can spell warranty correctly so that is one point for me.
Secondly, the article quotes Ford as stating "'NO ORANGE' coolant" in their systems, it says nothing about regular green glycol based coolants not being compatible, actually green glycol based coolant is compatible in every cooling system that is marketed in the US except and I mean EXCEPT GM DEX-COOL required systems.
The green glycol based coolant is perfectly fine in Fords gold extended life coolant systems, the only sideeffect is that it reduces the life span of the SCA's which then requires that the system be serviced with SCA's on a more routine basis. You can go and check-out Ford's website for this information (a little more reliable than some pdf article that is generically used to base a position on.)
Oh, and a WARRANTY is never "intact" it is either valid or invalid, or atleast where I COME FROM.

Well obviously, you don't know the difference between no effect and side effect. If green coolant was perfectly fine to add to yellow coolant, then there would be no talk of any "sideeffect". If green coolant were compatible as you claim, then there would be no need to add SCA's on any basis except per manufacturers recommendation which is NEVER. And then the manufacturers recommendation is to drain and refill with yellow when your maintenence interval is up, that's why they call it maintenence free coolant unlike your beloved green coolant that needs periodic maintenence between drains. What's particularly interesting is your truck didn't come with it, so why do you care? You didn't pay $40,000 for your truck that came with yellow coolant, so why are you so bent on providing costly misinformation to those who do have yellow coolant.
Any by the way, valid and invalid, are legal terms of art where I come from and warrantees that are as comprehensive as they are in automotive settings may be invalid and therefore void, or valid and partially intact, or valid and completly intact. Most people like myself prefer the latter.

colt, you said that there is no way that the coolants can be mixed or the engine is completely ruined. This is not true, the coolants are compatible there is no harm in using the green coolant so there is no reason the he should change the coolant right now because no harm will be done. And the 02 and 2 '03's that i have for lawncare do have the gold coolant, and no i didnt pay 40k because I know how to find a deal.
