If you grade performance based on miles and longevity, then I respectfully point out that Chevron Delo Heavy Duty ELC has better numbers than the CAT labeled brand.

Skip, read the first page of this thread where I post all the coolant info. Just read that and you'll see the best coolant for your 2000 7.3L is a Heavy Duty OAT based ELC. Don't use a coolant that needs SCA's.

When the manufacturer of the engine say's a HD OAT ELC is the correct and best coolant to run in the 7.3L PSD, then you can chalk up what you've read and experienced as a problem caused by something else, in my opinion.

All my 7.3's run Chevron HD OAT ELC, and the Excursion has had it since '04 or '05. In fact, I've had to flush the ELC already because of the 10 year limitation, and refill with fresh ELC.

There's no risk, Skip.

I have 30k on my reman 7.3 that I replaced at 318k miles an I have a cracked injectior cup.. I run delo ELC.. My mechanic says to get the delo out asap as it's not good for my engine and may have caused my cup issue... Based on my reading here I feel he may be misinformed... He recommended zerex what is the absolute best coolant to use after I flush my system? Also should I use simple green or so mythology clean the diesel out of my coolant system?

I put Zerex in when I bought my truck just over 10 years ago. Switched to Delo ELC about 2 years after that and have been running it since with no issues. I'm doing injector work right now (o-rings) at 305K and had no signs of cup issues. When I got the sticks out I had one cracked cup and some unusual pooling so decided to replace all 8 since I was in there already. I don't attribute that to my coolant though. They are brass and have been through 15+ years and 305K miles of heat cycling and vibration. IMHO I got my money's worth out of a $15 brass cup that mates to a dissimilar metal and helps separate 3 fluids at different temperatures and pressures.

I wonder if jasper installed new cups when they remanufactured the engine? I just can't see why after only 30k miles a cup would crack..

Walmart is about giving this away - $10/gallon. Is this correct for an 2001 7.3? I see 4 Rotella coolants on the Shell web page.

Its pre-diluted so its $20 a gallon which is not all that great. You can get the Delo for that. The undiluted Rotella is at tractor supply for 13.

Plus when you flush you have water left in the system so you will not have a 50/50 mix when you are done.

Very good points. $17/gal at my Tractor Supply, so maybe I'll wait for a sale. I do like buying a concentrate so that I can dilute to my preferred strength and accomodate leftover water in the block.

Thumbs up

Dang what an impressive thread y'all!

So, I've cut-n-pasted to a word-doc key data and the "Recipe" for the surgery.

for the record mine(is/are) e99's for this reference point.

Currently making the price list using NAPA, Stealership/online, O'rielly's, Tractor Supply & Amazon for parts. I will be doing this by end of the summer. I will also share current prices I found given the last post with pricing was ~2009?
A) Currently O'riellys D4985 concentrate price is the same as Tractor Supply here in Denton $17.99 /gal.
B) Odd note so far on pricing of parts, not found anyone where that you can get a "case" of the coolant filters, say, 6-12? I have not talked to the local NAPA shop yet.....

I saw someone make a reference to this thread:
https://www.ford-trucks.com/forums/9...a-c-mod-2.html
I had heard of the Ranger part mod years ago & finally have had time to do a slightly different method. Dual 3-way brass valves. Thru R&D my Alpha kit will be going toward my friends truck when they do their flush/fill. My Beta version will go on my (new to me) e99. I made 2 sets of aluminum "L" brackets to mount each setup on our trucks.

I also have a coolant filter setup ready to be plumbed into the system as well -- when the coolant procedure is done too. FYI picture visible in other post about pictures of your engine thread (smirks) a few months back... forgot to save thread in subscriptions to do a cheat-link. Sorry.

I am curious if the original suggestion of a 3 month filter replacement for sand extraction is still the logical plan over the first year from the flush/fill? OR if I should be more flexible and consider a sliding scale dependent of miles driven?

I buy my Baldwin filters from Application Associates. They sell them by the case and the more you buy the cheaper they are.

on the E99's you cannot just flush coolant and add ELC. You MUST redo cups with the correct green threadlocker, off memory i think its # 612
ELC is incompatible with the threadlocker sealant used on early engines' cups and will cause cup failure

edit: its # 620

BOOM....and it's been talked about it a bunch, but many doubt it and want proof. The chemistry just doesn't play well together.

Unhappy

For the record Wesley Green & BBslider001 I see I should of clarified that I am clearly planned on using the "Green" NON_ELC coolant. As it seems your post suggests I was planning on using ELC for some reason.
