Green Coolant

I repaced my upper radiator hose and lost about a gallon of coolant. (Green). I thought I could run down to my local NAPA store and pick up a gallon. I found out after doing numerous searches that there are several kinds of coolants and they don't play nice together. Any recommendations of what to buy to replenish the gallon I lost? I've got an ISX 525hp

You are ABSOLUTELY CORRECT-- color alone does NOT designate the coolant chemistry.


If you do not know what coolant chemistry is in there, given the cost of an engine, best advice is to flush and go with new coolant.



Most, when it is time to change coolant go to the newer OAT-based long life coolants. Completely different than the old-generation "Low silicate coolant for diesel with added SCA" coolant.

The poster is correct, I assumed you new what you needed since you went to pick some up. Call your Chassis manufacturer or look on you coolant tank for instructions as what to use. On my particular coach which is a spartan chassis it is listed right on the tank. That being said you can get most rv coolants today online.


I checked and you can get the information from any Cummins shop. Hope that helps.

In a word, NO. Asking what coolant was OE more than a decade ago is a good way to mix coolant chemistries!

If it's green, it's unlikely it's OAT.

Most non OAT, HD diesel fully formulated coolants are compatible.

Yes / No??

That's absurd! The manufacturer no more wants to suggest something that will hurt his engine anymore than the man on the moon. First of all you are assuming that in 10 years he has never added or changed his coolant. Yes coolants have changed and you really need to be careful, but to suggest asking Cummins what coolant should be used is somehow wrong boggles my mind. Either way adding coolant or flushing and adding new coolant if the op is unsure of what to add or replace the manufacturer is the best place to start. As I said for my 2 cents call Cummins and hear it from the horses mouth.

Just add water, unless you need a minus 32F freeze point.

You really can't go by color, HOWEVER here is a file showing cross reference for Fleetguard's different coolants.

Prestone states their antifreeze is safe to use with all coolant types.
This article from Hemmings explains auto antifreeze and its variations.

I believe the comment to not call Cummins (and ask "what type of coolant is in my engine now") is just because someone (previous owner) could have changed the coolant type. So Cummins can tell you what was in the engine when the Coach was new, but there could be something different in there now.

For example, my Coach came with ethylene glycol (green) with SCA. But I changed it out to Extended Life Coolant (red) two years ago.

I believe the chassis manufacturer is the one who adds the coolant. Engines are shipped and installed 'dry" and after radiators hoses etc are added to the frame only then is the coolant added.

That is true. But the chassis manufacturer/Coach builder puts in the coolant that engine manufacture specifies for its engine (for engine warranty)
