While reading in the UOA section about 6.0 diesel problems. I thought "if this were Dexcool". With all of the problems coolant related failures of the 6.0, why are there so many fans of it? With all of the plugged oil coolers, why doesn't Premium Gold get the ridicule it deserves?
Why does Ford Premium Gold get so much respect?

probably because 1) the coolant has absolutely nothing to do with plugged oil coolers and 2) G-05 is in use in millions of vehicles without any coolant related issues.
If you want to argue that Dexcool is unfairly blamed for problems, that's fine--but why extend the same flawed logic to other coolants?

The issues aren't related to the coolant, they're mostly issues with that particular engine that probably happen regardless of coolant choice. I've never seen or heard of issues relating specifically to G-05 (Motorcraft Premium Gold, some Mopar coolants).

Not defending dexcool, it clearly has had issue in the past. I have more miles with dexcool than probably 99.9 of the people around here and had some problems and had good success with it.
What was plugging coolant passages? Not drop out?
Don't attack me I'm just asking the questions.

How do you know they are not coolant related? I ask because I don't know?

If I didn't have G-05 in my cars, I would fill them with it.
I love the stuff.
G-05 is not to blame. The 6.0L was an utter failure from the start. First, the design of the oil cooler is flawed. It has WAY too small passages.
Secondly, owners who installed a "real" spin-on-filter style coolant filter, experianced no failures. People have surmized that the left over casting sand in the block is to blame. If you take a brand new 6.0L and drive 10k, the filter will be packed with [censored]. My friend does his every 10k and it is nearly clogged.
If you are not aware, this is not uncommon at all on almost any engine built. But the passages are large so no harm.
I personally ran my boat onto a sand bar by accident. No doubt there is sand in the bottom of the block. But it is not affecting the cooling and everyday operation. Place this engine in a car with a tiny heater core and radiator and that sand may work its way into those.

We love the 6.0 at my work, keeps the door open fixing them. As stated above, the coolant isn't to blame, International Navistar's design is to blame.
Oh, and G-05 chemistry is not flawless, its just very good.
It still leaves some deposits, just not as much as green.

I strongly believe that had ford used something else other than G-05 in the 6.0s there wouldn't have been near as many problems. International used red ELC coolant in those engines in their applications and did not have near the problems. The red coolant being silicate free.
The coolant was responsible for plugging oil coolers. I have seen it first hand. The silicates come out of suspension and form a nasty goop. This goop plugs the oil coolers and cuts off flow to the EGR cooler. That when the problems start happening.
I have seen way to much silicate drop out in various vehicles using G-05. I'm not a fan of the stuff. There are better coolants out there.

Did the International 6.0 in commercial service come with a coolant filter?

I actually think Dexcool is the better coolant in a cooling system that's set up right for it. I really don't see G-05 having much if any advantage over conventional Green especially in a gas powered engine. The service life is really only mildly increased. But I guess a little longer service life is worth something.
There was some cases of heater core problems in some Fords with G-05. I don't remmeber the details and maybe the G-05 isn't totally to blame. Ford is moving away from G-05 to Dexcool and has seen the light.

International actually recalled and installed coolant filters on the trucks equipped with the 6.0 after they were plugging oil coolers and rupturing egr coolers. The one flaw with ELC is it takes roughly 5,000 mi. before adequete protection is achieved, vs. immediate protection with a low silicate coolant.

IIRC, the EGR coolers are guilty of doing the same thing.

^ That's probably the case. Combine that with a lack of coolant filter and small tubes in the coolers, and bad things are likely to happen.
The G-05 was never meant to be used in a heavy duty diesel application. That's the problem not the oil cooler or EGR cooler. They both get hot, that's the nature of the best.
The 6.0 oil cooler is flat plate type heat exchanger. Very efficient but has very small easy to plug passages.

Yes, they both get hot and the EGR coolers fail, and they fail in any application with whatever coolant is being used. They boil the coolant. Slammds15 went through two of them, International parts, with International coolant, and it being a 15 hour job to change, he deleted it after the last one.
