Ford Gold to Cat ELC

[mazsecond]

My trucks oil and EGR coolers failed about 15K miles ago. I had Ford do the repair $1900 (this was before I joined the forum and got so informed about these engines) they flushed with VC-9 and put in a new oil and EGR cooler. I installed a coolant filter a few thousand miles ago. On my first filter change I cut open the filter and it looked really clean. Since my cooling system has been flushed and my filter is clean would it be ok to just do a distilled water flush and fill with CAT ELC? I don't want to risk clogging up my new oil cooler but since my trucks cooling system is suppositly free of all the iron deposits that clog the cooler wouldn't it be ok?

I do it all the time, even unplugged oil coolers with dish soap.
Never failed us yet.
But a clean coolant filter is great news while using the Gold.
With ELC and 3 filter change I have never picked up any dirt in my filters,

It is recommended to flush it w/ VC9 or equivalent before switching. I switched with only water flushes though and have seen no problems, but it has only been 5k miles.

IMO the reason why the chemical flush is recommended by the makers of the ELC is because ELC is advertised to help with heat transfer. That is (IMO again) because it does not deposit a nitrite layer (like the Gold dioes) for cavitation control. The nitrite layer hurts heat transfer a little (very little).

I am also very interested in how exactly you accomplished this. Dish soap? Idk that sounds like a stretch to me.

Looks like this thread will get interesting.

I am a commercial transport mechanic and this is a very common trick in the trade to clean out a cooling system after a oil cooler has failed allowing oil into the cooling system. The dish shop is used to remove the oil from the cooling system. Using dish soap while flushing your 6.0 isnt going to accomplish anything unless you have oil in your coolant. The reason we flush our 6.0's is to remove other contaminants that dish soap will have no effect on.
