Unless you are a chemist I would not fool around with anything other than distilled water and that coolant. I think he’s saying you should use a filter without DCA 1 Link to comment Share on other sites More sharing options...
tmw188 Posted November 25, 2023 Share Posted November 25, 2023 Kevin just a FYI if you didn’t know SCA’s and DCA’s are the same just called something different. SCA - Supplemental Coolant Additive DCA - Diesel Coolant Additive 1 Link to comment Share on other sites More sharing options...

Thanks Jim, that will be helpful when I next change my coolant. I want to get away from SCA's on my next flush and change. Link to comment Share on other sites More sharing options...
Dennis H Posted December 24, 2023 Share Posted December 24, 2023 MODERATOR EDIT. THE SUBJECT OF WHICH COOLANT AND SUCH IS A POPULAR AND OFT DISCUSSED TOPIC. THIS TOPIC IS COMBINED WITHE LAST CURRENT ONE. END OR EDIT I've never had to add engine coolant (yet) to my Cummins driven coach. That said, I've always had the SCA checked during our annual service but the coolant has never been low. Given that I've now broached the subject, I'll probably see a need to add coolant in the future. Therefore, I'm looking for advice on what to carry in case of emergency or the need to top off the radiator. Is there a special blend required for diesel engines or just grab a bottle of Prestone and be on my way? Thanks for any input. BTW my coolant is green, if that matters....thanks..Dennis Link to comment Share on other sites More sharing options...
96 EVO Posted December 24, 2023 Share Posted December 24, 2023 (edited) Usually labeled as Heavy Duty Diesel engine coolant. Check the label to make sure it's pre-charged with SCA. Usually states it's safe to mix with other non OAT coolants. The back label should also list the different engine manufacturers spec's that the coolant meets!

Ivan K Posted December 24, 2023 Share Posted December 24, 2023 Don't use Prestone for your ISX. Fleetguard Conventional Green Coolant Cc8974 or equivalent sounds like what you need based on the color. 1 Link to comment Share on other sites More sharing options...
Scotty Hutto Posted December 26, 2023 Share Posted December 26, 2023 On 11/23/2023 at 10:44 AM, tmw188 said: Yeah everyone throws that added requirement in. (Or 1yr) I think they say you can freshen the system up up by draining a few gal and adding fresh coolant to it. I sat thru one of their webinars awhile back. I talked to the presenter about maybe presenting at one of the Gatherings. Not sure if he and Scotty ever connected. We did, but… no Gathering this year. 🫤 Link to comment Share on other sites More sharing options...

birdshill123 Posted February 19 Share Posted February 19 I would either call Cat tech support or look online for their pages of info on Coolant requirements. Cat has some of the best support of all the engine mfrs. Link to comment Share on other sites More sharing options...
tmw188 Posted February 19 Share Posted February 19 (edited) Fleet School is having a live online seminar on Coolants coming up 2/21 this week. It is very informative and interactive.

dennis.mcdonaugh Posted February 19 Share Posted February 19 I’ve been running Final Charge in my coach since around 2008 and changed it again in 2017 when I had a hose fail. I drained the system and replaced all the hoses - including the heater hoses - and refurbished the metal pipe. I have not tested the coolant, but I only put about 70,000 miles on the coach in that time. 2 Link to comment Share on other sites More sharing options...

I flushed my cooling system and switched over to Fleetguard ES Compleat back in 2008, within a year of purchasing our 2003 Dynasty. Then in 2016 I had a water pump failure while on vacation out of town. I was fortunate enough to be able to locate a water pump and repaired it at the campground. Upon returning home I drained the system, replaced all radiator hoses, coolant hoses and then flushed the system several times with distilled water until clear. I then switched over to Peak Final Charge coolant. It is currently @ 8 years but only has about 45k-50k miles on it. I purchased some test strips and tested it a few weeks ago. It is still like new condition so I will continue to run it a while before replacing. 1 Link to comment Share on other sites More sharing options...
Bill R Posted February 21 Share Posted February 21 @96 EVO Ben - I won't be able to attend the seminar, but I have been told that the Fleetguard ES Compleat EG is a "Hybrid" coolant that contains both SCA and OAT additives. If they mention this can you report back what you hear? Thanks, 1 Link to comment Share on other sites More sharing options...

Benjamin Posted February 21 Share Posted February 21 (edited) Yes, ES compleat is hybrid, the picture on the first page states nitrites, phosphates and silicates, none of which are organic OAT. ES compleat OAT is strictly OAT, Es compleat NOAT has nitrites which makes it hybrid in my book, but it seems they have a separate category for NOAT. https://www.owi.com/binaries/content/assets/documents/brochures/heavy-duty-coolant.pdf Old World Industries is PEAK, and makes many OEM coolants, so I trust their info. Notice many ELC, OAT coolants are actually NOAT or hybrid. If you read deeper into the weeds, you'll find Cat mixing ELC extenders with SCA bases, or Cummins Fleetgard had a procedure to "convert" SCA to ELC OAT type, which would be a hybrid of sorts. As far as I can tell, aluminum radiators are the biggest thing that pushed OAT, so if you replace a copper radiator with aluminum that's a good reason to switch. But if you're still running a copper radiator, then SCA is nicer to your radiator, as long as you test or send in a sample. edited to add: not sure how much I trust this site, but I'll throw this into the discussion as well: https://gmb.net/blog/inorganic-vs-organic-coolants/ Edited February 21 by Benjamin 2 Link to comment Share on other sites More sharing options...

If they mention this can you report back what you hear? Thanks, I had submitted a question about my current hybrid coolant since i used Zerex last time, due to availability, and already had a discussion and an answer, in case it helps you too. He said the 3 way test strips would be an incomplete test on this HOAT and recommended their lab test kit. From Fleetquard Materials Science Engineering Chemist: .....While we try to recommend people using a full OAT for longevity and ease of service, hybrids still get the job done. Given that is it only about 2 years old and 20K miles on the coolant, I would expect it to have plenty of useable life left. As Jay mentioned though, the only was to know for sure is to test it. We sell Kits to have them sent off to a lab and they will give you a report back with some general information and overall health of the coolant. The part Number is CC2706. If you have any additional questions or need help with the lab report feel free to reach out to myself or Jay. 1 Link to comment Share on other sites More sharing options...
