2014 Cummins Coolant Confusion

[Newsa]

When doing the Vin number check the dealer comes up with that my truck was in fact filled with the 5 year coolant not the 10 year stuff. After my water pump swap out yesterday they filled it back up with the 5 year stuff....

No decal on mine.

Oops, found the decal. It us the same as Brockman's. EDanckovich, see if yours was filled wrong. You may have a claim

 

[EDankievitch]

The Parts guy looked my truck up by the Vin number that gave him a full sheet of everything that went into my truck when it was built.
Now for the Million dollar question... What is the difference between the 5 year 100k mile stuff and the 10 year stuff? if they are both the OAT coolant then there should not be an issue?

What does the decal on your coolant reservoir say???
5 yr/100k is HOAT
10 yr/150k is OAT

This was discussed as a major change in the 2013 model year, along all model lines, not just RAMs and CTDs.

MS.90032 vs MS-12106


The 2016 Diesel Supplement, page 292, says to use MS.90032 coolant. The coolant reservoir sticker on my 2016 says to use MS-12106.
2018 Diesel Supplement also says MS.90032 coolant. How is MS.90032 different from MS-12106? And which one should be used when the manual and sticker disagree?

 

[EDankievitch]

I'm confused. Both the Orange 5 year mix and the Purple 10 year are OAT mixes. What is the issue with mixing them? The Vin number says my truck was filled from the factory with Orange 5 year. The sticker on the burp tank says it should be Purple..... I see Orange stuff in the tank and that is what blew out when the "Y" pipe failed.

 

[Kirwin]

It looks kind of orange/pink in the tank. Lighting is critical.

 

[TRAMPLINEMAN]

When my y pipe broke, it sprayed orangish/pink coolant all over the engine compartment and leaked all over the snow that was under the truck. It was orangish/pink. My tank has the MS-12106 sticker on it. I had the system flushed last week and it now has purple in it.

No one has asked the question, do rubber radiator hoses and heater hoses last more than 5 years? I sure wouldn't expect them to not need changing sometime in a 10 year period. To me there is no point in changing hoses and not doing a flush/refill at the same time.

I’ve got 100K miles on the truck, but it’s only 4 years old. Hoses should last more than 4 years.

 

[GAmes]

The key word is should, and if you never go far from home I suppose it isn't an issue. The tires on my beater pickup are over 7 years old, but since it is never more than 15 or 20 miles from the house I don't worry about a flat. On the other hand I change my hoses every four years on the Dodge. The last thing I need is a coolant leak when I an thousands of miles from home. Are you going to wager your hoses last 10 years?

 

[Paul Herioux]

In this case it really does matter. There are two major issues with mixing the 5yr HOAT coolants with the 10yr OAT coolant. the first is that the rust and corrosion inhibitors react with each other and cancel out their effectiveness leaving you with a substance more corrosive than plain water. The second major problem is that in the right proportions mixed with the right operating temps the coolant congeals into a substance resembling finger jello. If this does happen the only real repair is a complete new cooling system including long block.

of course hoses last more than 5 years. seen em last 20 years.
FWIW with all the coolant conundrum you all are discussing, I suspect its just FCA coming up with their own offbeat little coolant designation that completely matches some of the bigger guys coolant recommendations but has its own esoteric numeric designation that is leading to all the confusion. plenty of coolants on the market that are compatible with just about anything.

10 years, maybe. Then again, maybe not. I probably won’t keep this truck long enough to find out. I understand preventative maintenance, but where does one logically draw a line?

its easier if you have a fleet and you have data to compare so you can draw a baseline.. other than that you make a strategic guess or depend on visual inspection on a routine basis

Exactly! Mine look and feel like they’re brand new. So why replace them?!

 

[Bob4x4]

What kills hoses is electrolysis.When the coolant is in too long you can measure a voltage.This flow of current damages the hoses from the inside out.Our Cummins do not have much of an issue with this,very rare you will see this type damage on ours.

Mine looks red in the reservoir. ??red, orange, pink, purple?? Sticker...

Some you can mix, some you cannot - scary and crazy. I guess best to follow the suggestions on the web. #ad
or in the supplement.
