ELC Coolant flush

[mxfever090]

I searched the forum for the flush procedure to change a 7.3 over to ELC and all I find are topics related to 6.0's. Anyone know the procedure or provide a link to another thread?

Thanks for the help

Coolant changing instructions... - Diesel Forum - TheDieselStop.com

I used this write-up this past summer and switched to the ELC along with installing a coolant filter. Not too bad of a job and I'm glad i did it.

That's the one I used, do a little search on gooch I doubt anyone knows more about coolant. If gooch said piss was the best 7.3 coolant that's what would be in mine...lol

I heard or read that some of the seals & the sealant used on the injector cups wasn't compatable with the ELC. I think gooch had the info on one of his writeups

i didnt see it on his but this link i just read explains it all

Any early 99 owners running ELC antifreeze? - Ford Truck Enthusiasts Forums

Thanks PolarBear! That's exactly what I was looking for. Did you recenlty put a leveling kit on your Platinum truck? Looks good

Now as far as the 99 goes. My buddy is going to change his truck over to ELC. (we both work with Cummins and get Final Charge ELC for 7 buck a gallon) It's a 99. First where is the engine serial number so we can verify build date? From what I recall early 99 can be identified by the powerstroke badge in front of the wheel well.

My e99 has badges on the door. its a 9/98 build.


the date is on a sticker on the driver valve cover. or look at your id tag on the cab behind the driver door. the cut off is 12/98.

My buddies truck engine build date is 9/98 and serial is 0847458. So he is technically to early to run the ELC. Is there any other recomendations other than stock coolant with the additive?

Thanks, ya I did have some Skyjacker 2.5 inch springs put in the front and an inch taller block in the rear. I love how that truck rides. As far the early 99 coolant, I'd still go through the whole flush process and then get some of the good heavy duty truck coolant from NAPA. I'd still go concentrate and mix with distilled water to get a good solid amount of antifreeze in it. The green isn't too bad, that's what everything had in it before Ford's great idea of putting in the Gold. My 99 and 01 had green before I flushed and put in the red ELC.
