ELC ???

Is anyone running ELC in their 6.4? If so did you flush your system before switching?

Needs to be flushed if switching to ELC. There are chemical components that dont go well together if I remember correctly.

When I switched over to CAT ELC I flushed with CATs flushing fluid. It was $30 for the gal. Good enough to flush our trucks twice. After I flushed it I then added 8gals of distilled water and got it up to temp again with the heat on. Then drained the block again. Then filled up with 4gals of ELC concentrate and topped it off with distilled water took almost 4gals.

you havent had any problems after the flush or with the elc? How many miles on your truck when you did this?

I'm running the Fleetrite ELC. After draining the system and doing my EGR delete I did 3 flushes with distilled water. Then put in the concentrate and added more distilled to finish it. I didn't use any chemical flush and never have in any of my trucks. That may not be the "correct procedure" but has never given me any problems. My 6.4 is still going great at 108K.

That is exactly what i was thinking of doing. So there was no reaction between the gold and ELC? I want to do that i am just not sure how well just distilled water flushes the system by itself. How long ago did you switch? Maybe i should just do a VC9 flush and then water? I am so confused on what to do . All i know is i want to run EC-1 ELC.

I did this today. I drained everything and refilled with filtered water and two bottles of prestone super flush. Went for a long slow cruise with windows open and heater on. Got home and drained again. Then I filled with distiller water and went for another ride. Got back and drained again, took plug out of block and loosed bottom hose. Then I filled with 4 gallons Zerex elc ec-1 and topped off with almost 4 gallons of distiller water. Suprising was the first to drains the old coolant was pretty clean. It had 64k miles on it. I was expecting more trash to come out. Hope this helps someone wanting to do this.

Haven't had one issue. I did my flush at 43k. I only had 7k on that coolant since I had head studs and an EGR delete installed along with a new radiator installed at 36k.
