I found some 50/50 mixed Global coolant that is Cummins approved at Wally World but its also on close out.

 

Personally I try to avoid the 50/50 premix stuff, especially when I've flushed the system.

Sometimes a gallon or more of water can remain in low spots, and I've ended up with less concentration than intended.

I much prefer to start with 1/2 or a little more of the published cooling system capacity with anti-freeze, then fill the rest with distilled water.

 

I went on a HOAT search today and ended up getting the MOPAR stuff from the dealer at just under $18/gal. I got the orange 5yr 100K stuff; I hope this is correct? It says nothing about HOAT on the jugs. In fact, I found nothing that said HOAT. I found two others that claimed to be Cummins approved: Delo long life and Fleet Charge. The former claimed to have passed the John Deere cavitation test, and the latter claimed to have an anti-cavitation additive. Any feedback on these coolants would be appreciated.

Thanks,
Nick

 

HOAT seems to be harder to find. I don't understand why the MOPAR antifreeze says nothing about HOAT when DC is requiring it?

Dieselnick: Did it come in a blue/grey jug? I didn't open it, I tried to return it.

DBLR seems to believe the mopar coolant is for their cars, and I tend to agree, since it don't mention Cummins or HOAT on the side of the jug.
I'm mad that autozone quit carrying the Zerex G-05.
They autozone, now stock what china-mart carries, for $2 more on the gallon. Genius.

 

It's in a black jug with the blue/white Mopar label. It's what the truck came with so I'm assuming it's OK.

If nothing else do you have a Cummins dealer or big truck shop or truck parts place near by? I would think they would have the proper coolant for use in CTD engine or would hope they do.

 

Hello,

This is hard to swallow. Do you have technical info or a link I can research? Cylinder walls moving so violently that cavitation occurs? I have not heard of that. Seems like the ring seal would fail in a few hundred miles with that type of motion occurring. Since diesel blocks are made of compacted graphite type of cast iron that is stronger than car's engine block cast iron I am having a hard time with this.

Thanks for any info.

Good thing I read this b/c I'm at 98k right now and coincidentally 5yrs old. So, I've been saying that I needed to change the fluid soon. I do have the manual and the Chiltons manual so I would've figured out the type of fluid but now I know where to start looking. So, as usual, good thread.

 

I've come to the same conclusion. The factory service manual states 28 liters for the 5.9 diesel. I have drained the system and refilled with 15 liters of Zerex GO5 and 5 liters of water. That left 8 liters of water somewhere in that block? This is with the rear tires on 12" of blocks so the block was close to level.

 

IIRC cavitation happens in Semi engines due to the fact they use drop in sleeves/liners. The 5.9 does not use sleeves/liner so it should not have as much of a cavitation problem like the semi engines do.

 

I was going to say the same thing... That my understanding is that cavitation happens with sleeve type motors, I presume because the coolant passages would have more abrupt angles, so the cavitation issue and anti-cavitation additive doesn't apply to the 5.9.

Anyway, I have the dodge factory manual, and it doesn't mention any additive being required for the diesel.

 

I have been meaning to post this pic. I bought this at my local Mack truck dealer, my cost was just under 10 bucks.

I had a hard time locating Zerex G-05 HOAT coolant until I happened upon it at the local Tractor Supply store. If you have a store nearby, check there, and they generally have good prices, for Chinese junk.

 

I love that store.

Is this for sure!!! I just bought G05 Zerex and it is yellow. My reservoir is on the low side when cool but I can see it is orange/red. I suppose the two are compatable??
