Blue Coolant!?

So- I've checked my coolant a couple times on the shorty and it was at the add mark. Looks clean and nice, but its BLUE. It looks like washer fluid, and with all the stuff that seems almost "sabotaged" on my bus I was wondering if the bus guy in TX had put washer fluid in the coolant to be a jerk. But I found Fleetguard and some others make blue coolant, and every filter on the bus was Fleetguard when I got it, so I'm going to assume that's why my coolant is blue.

Upon googling it, the stuff seems to be 150,000 mile coolant that holds up real well and doesn't need additives or any of that stuff.

Anyone familiar with this magical BLUE coolant in my bus?

Read up about additives, Charlie.

Most, and especially wet sleeve, do just fine with regular ethylene glycol, but they need additives and regular checks to ensure the additives are still effective.

It's worth doing the checks because life of the coolant can be extended to seven years or 150000 miles, and with up to 15 gallons of the stuff in some buses, it's worth taking care of it.

The best info on coolants will come from whoever made the bus. Cummins, btw, give out lots of great advice on coolants.

that newer DT466 wouldve been shipped with an extended life coolant in it. many of those coolasnts dont need SCA's. if its just the simple "green stuff" in a blue color and not an ELC then you will need to still measure and use SCA additives..

its always tough when someone has changed something.. unfortunately coolant colors are not universal as they should be.. manufacturers seem to go off on their own tangents.. I would ask Navistar what coolant they recommend be put into it and go from there..

Fleetguard does have a coolant that's blue that is called ES Compleat. It's a hybrid coolant that uses both, organic acids and conventional additives, and is a lifetime coolant. You use test strips to check for acidity, glycol %, and additive level. If the additives are low you have the ability to correct with DCA4 from fleetguard. It's Pretty good stuff and IMHO I'd check it, and if found to be good, leave it. This isn't as good as the full OAT coolants that most oem's use in new ones but it's still pretty good stuff.

I'm pretty sure this is the stuff that's in it.
I'll find out soon from the maintenance manager at the bus yard it came from.

Sound like good stuff-

Quote:
Compatible with all other coolants
Lifetime coolant with service interval at 150,000 miles, 260,000 kilometers or 4000 hours
Provides freeze protection up to -34 F (-37 C) at 50/50 premix and -65 F (-54 C) at 60/40 premix
Fully formulated coolant does not require SCA precharge
Maximum corrosion protection with conventional heavy duty chemical inhibitors and organic acids
Maximum liner pitting protection
Eliminate hard water scale deposits
Low TDS and silicate levels
https://www.ryderfleetproducts.com/f...n-p-v52-cc2825

Not even any more expensive than store brand autozone junk.

I'll get some test strips and go from there, but I'm planning to fully replace the coolant before summer.

Seems Cummins was or is running the blue stuff!

I'll look into additives, thanks!

Never seen blue coolant!

Possibly some kind of corrosion inhibitor additive? Just add some of that yellow stuff that will turn it back green again.

I know nalcool was purple. It's a napa corrosion inhibitor. Most of your water filters have some sort of DCA now.
