The 6.0l is not the only engine that is made with silicate sand, I think it is a standard for casting. If this was the real problem then radiators would be plugged up. Silicate drop out coats most of the metal in the coolant system and it can't be removed. The silicate drop out issue is a big deal big rigs. I could never buy the casting sand theory but if the antifreeze type is the issue I don't understand why Ford with all these problems plaguing them didn't change the antifreeze.

 

Casting sand does remain in the engines and does come loose - some engines more than others. It simply is not large enough to plug a radiator (at least in most cases). Check out the size of the openings in the oil cooler passageways and compare that to the radiator openings. Whether you believe it or not, the chunks I removed were pretty much proven to be casting sand. I know that I have some pluggage of my oil cooler since my deltas are in the 8-12 degree range - but they are not getting any worse, they are stable.

Also, do the calculation for yourself on how much silicate is in the 27.5 quarts of Gold coolant. It simply is not that much as I stated before. Silicates can complex with water and produce the colloidal solids (goo), I certainly will admit that this condition is all too common - definitely an issue!

Lastly, how do you explain the MANY folks like myself and Tex2505 (especially him) who have no issues with the Gold. He has 500 rwhp, tows heavy, still has the original oil and EGR coolers. Both of us w/ enough miles to have seen something if the Gold coolant is proven to be the sole issue.

For this reason it is impossible for me to blame ONLY the Gold coolant .....

BTW: ASTM 3306 standard for the Gold coolant states 250 ppm silicon by weight (max) for a low silicate formula. That is at most 0.01 pounds of silicon (or 0.032 lbs of silicates SiO4) in 4 gallons of concentrated Gold Coolant. That is 1/2 of an ounce of silicates.

 

Mark, I agree with you on the Gold not being the whole problem. I don't think that it is bad, but niether is ELC. So for me I would rather run the ELC, and not worry about it. Not that I really ever worried about the gold, but I do like the ELC not having silicate. I don't really recomend that everyone switch to ELC, but wrather (like I said before) if they do just make sure they put in EC-1 ELC. I still stick with what I have always said don't use anything other than Ford Gold or Zerex G05. I just added Cat EC-1 certified ELC to the list.

 

Just how would that work? Maybe with the aid of a Ronco solid flavor injector?

 

By sending it to a lab!!! There are plenty of places that analized stuff to determine the makeup.

 

Hello! Anybody home?

After you analized her, the evidence was analyzed at the crime lab.

Analyzing = Doing an analysis.

Analizing = Could be illegal in 38 states, including Texas. 42 if you do it to an animal.

 

Sorry my spelling doesn't meet your standards sir, but i'm pretty sure that everyone, including you, knew what I was talking about.

 

Hey texans! Don't worry about it. I caught it last night and snickered to myself. I would't bust nobody's chops about it though, my spelling's not good enough. Gotta admit it was pretty funny though (cause it was about the butt- that stuff has been funny since 3rd grade).

 

I think the 6.0L comes standard with hypochondria....myself sometimes too...hahahahaha

 

Hey, no problem.. It was the first new thing anybody's posted about coolant in ages.

 

I think hypochondria was an option on our trucks. If you didn't order it from the factory, you can catch it on websites like this for free!

 

I just cut my old oil cooler in half and there was No Goo I DONT think the ford gold caused my oil cooler to plug

by the texture of the stuff Im pulling out seams like casting sand

I averaged 25-30* spread and I bet 1/2 the coolant passages were plugged solid and the rest were not to far behind

oil passages were clean but looked twice as big

there was no amount of flushing that would have cleaned my oil cooler coolant passages

 

hell yea amen brother!
