Think I've read something a year or so ago about coolant needed for my radiator. Just searched a bunch of pirate writing from 5 yrs ago with no help. Brett(or someone) tell me wnat to put in my radiator. Haven't driven it since getting it going again. Not going to until I check coolant(won't do any good if it's low and I don't have proper stuff to add....think I'll go back and learn some more pirate lingo. Didn't realize this has been going on for so long.

Just refreshed to check my post and discovered pirate lingo in MY post. HOW??
Jim,
At this point, really don't know what is in there-- hopefully, not OE coolant!
Two types of coolant are approved for your engine:
Low silicate coolant for diesels with added SCA (Supplemental Cooling Additive)
The new generation OAT-based coolants for diesels.
If you want to avoid a complete flush and rinse, stick with the type that is in there now.
"Regular"/automotive Prestone is NOT acceptable for your diesel engine, though Prestone certainly makes coolants of the two types listed above.
How does one guess what's in there now?
Jim
I got it directly from Cummins themselves........the horses mouth so to speak. Their tech told me to use ANY coolant as long as it says "Meets Cummins 14603 specifications" on the jug.
You don't unless it is green. If green, then regular coolant, if red, can be anything.
Yup, most likely green= low silicate coolant.
Is green bad? My ism has green elc.
Learn something new every day. I didn't know ELC ever came in green.
Green and says extended life
Concentrate
That is Ethylene Glycol It is not the ELC which is Organic Acid Technology formula and is red.
When in doubt, flush 'er out
The Front says Extended life ..Different?
Yep, not the same stuff, I am sure others will chime in. A lot of manufactures call their product extended life, but the true ELC OAT is 6 years and 600,000 miles and an earlier post had a rep claim that in our motorhomes we could forget the year limitation and basically never change it.
Just realized the link problem might have something to do with pirates day lingo. The link below might work tomorrow.
Shell Rotella® ELC Extended Life Coolant Extender (http://www.foreforums.com/index.php?topic=14152.msg81134#msg81134)
Yes, different..... diesel engines with wet sleeve cylinders need a low silicate coolant with SCA (Supplemental Coolant Additives) or the new OAT (Organic Acid Technology) type coolant. I changed mine out to Peak Global Final Charge OAT, good for 6 years / 600,000 miles.
I think that I will change it at 500,000 miles just to be on the safe side...... 8)
:o , I promise ..... I don't really talk (or type) that way!
site has been hacked by a pirate...........
If it is unknown what is in the cooling system, or unknown is how old whatever is in there, and what ratio to water it has, why not start over with all knowns. Drain, fill, drain, fill, drive for a short warm up, drain, repeat as many time as you want. Then fill with correct number of gallons of whatever you choose, top off with distilled water. Drain & fill big plastic overflow container with same stuff. Years ago, between water fills, we cleaned the insides with both of Cummins coolant cleaners, adding a gallon of Cummins acid-type cleaner, then added a gallon of their alkaline cleaner, flushed it all out and then added our choice which is Cummins Compleat EG
Did this with last and my most recent U295, your post spells it out accurately, I also used the Cummins Fleetguard, ES Compleat™
OAT* "Lifetime Heavy Duty Fully Formulated Antifreeze/Coolant
Nitrite, Amine, Phosphate and Silicate Free". I like not having to check the SCA's and the 1,000,000 miles is nice. I also will change at 500,000 miles, I only have 497,500 to go. Also Napa, Wix, Fleetguard all sell the none SCA coolant filter which has to be used with this coolant.
Cummins sells an ethylene glycol based extended life coolant. That is what the Cummins dealer put into our coach when I had the cooling system flushed and refilled. I don't care how long it is good for I will have my system flushed and refilled with the same stuff after several years use. Not wanting another transmission cooler failure one is enough; flushing and refilling a lot cheaper than a transmission rebuild or replace. Over cautious absolutely.
