super duty service, I see what you are trying to do. you are trying to discredit me by questioning my knowledge, when you in fact are the one supplying a bad recommendation. If you know procedure so well you will know the TSB Ford Motor Company released that showed what a flushable cooling system was and what a lost cause was. At no point in time did Ford recommend to use diesel fuel. Ever. I have done enough to know simple green works and works well. I have never had a come back. I have never had a complaint. I have never used diesel fuel to flush the cooling system. You can only attack me because you don't know me - but I will be the one using simple green.

 

So only the Ford procedures can be followed?

 

Had an intake leak on a vortec 350 once and filled the engine with milkshake.
Although that engine is way different then the 6.0 I dumped diesel in the engine , ran it through and drained. The inside of everything was clean as a whistle and all I changed was the intake gaskets. The inside of everything was clean as a whistle and still never had to replace any parts 5 years later when I sold it.

 

Should I get the popcorn and Pepsie ready cause someone just grabbed the bull by the horns

 

REALLY?? My response was to the statement that "simple green wont touch this issue" Please feel free to put diesel in your coolant system. If your research and development budget is larger than Ford Motor Co. and you can afford to risk diesel saturation of your or your customers rubber components go for it. I stand by my recommendation to the op that simple green will work. Transmission fluid might even work, but I am not going to recommend that either. Who else has used the PH neutralizer designed for this issue?

 

PH Neutralizers only treat the water/coolant mix it does nothing at all to oil or anyother petroleum product. It simply makes it neither acid based or alkaline based water.
Just like a water softener for your house.

If you want a surprise take a test strip and dip it in a glass of your house water especially treated city water.

 

I've used that "who's got more money than Ford" comment many times. Especially with injectors. However,,, There was a time (and they still might recommend it) that caterpillar recommended diesel for this type of failure. So here's the question,, who has more experience with ruptured oil coolers in diesel engines??? Cat,,, or Ford?? I wasn't trying to discredit you by my statements,, however I can understand how it was perceived as being such. But I've done both,,,, simple green,, and diesel. And I'm not sure I have done more of these repairs than you,,, but I have done my fair share. So if you want to be upset with me,,, fine,,, but I'm not gonna hold my tongue when I feel there's a more efficient way to do a repair.

 

I think I'll revise my earlier suggesting that included using SG.......Another issue with Simple green might be a factor to consider is the possibility for corrosion of unprotected aluminum (like the radiator core)

According to "Simple Green"
(Emphasis Mine)I was always told to keep that stuff away from airplanes in general.......

Since we pretty much ALL have aluminum radiator cores, AND In view of Simple Greens own FAQ above, I wouldn't pour that stuff in my cooling system, ever!

I have used diesel and kerosene to clean rubber parts and even left them saturated for a time and never had them "melt"!

Since diesel and kerosene are lighter than water, they would float to the "top" of the cooling system at least as quickly as regular oil. (quicker in fact because the viscosity of diesel/Kero is MUCH lower than oil.

Following through with a surfactant like Dawn (or other dish detergent) would quickly emulsify any diesel left in the system.

And you wouldn't have to worry about the radiator core or other aluminum parts of the system....
