Coolant?

[bereta1]

Some time ago I purchased Mopar coolant (68163848AB). Want to make sure I can use it in my 2016 1500 Ram 5.7L .I guess the part numbers have changed.

The 16 takes the 10 yr 150K coolant, not the 5 year 100K coolant. Very different and if mixed a disaster. Get the correct coolant. I opt for the full not the pre mixed as I need below -35° protection.

You will be able to tell the difference by color and price

Your part number appears correct for the 10 year

2015 is not dex cool but it is a dex clone, without the bad thing that messes up cooling systems. 2015 for sure is 10 year coolant, only use mopar 10 year coolant.

Agreed and don't let a parts store tell you universal will work. Buy Mopar.

I must be gettin' old......I can't believe how many different coolants there are out there now. Thanks to the experts for posting.

Everyone should protest
Everyone of the Coolant companies are purposely trying to get you to buy their product by confusing you.

From Popular Mechanics
OAT coolants are usually orange, yellow, red or purple. HOAT coolants are orange and yellow for the most part. Then the older IAT coolant is green.

From Valvoline, they don't even mention OAT CoolanT for Rams

TYPE	INHIBITOR TECHNOLOGY	ZEREX COOLANT	VEHICLES	COLOR
IAT (Inorganic Additive Technology)	Silicates	Zerex™ Original	Older Vehicles	GREEN
OAT (Organic Acid Technology)	Organic Acids	Zerex™ Dex-Cool®	GM, Saab, VW	ORANGE
HOAT (Hybrid OAT)	Silicates & Organic Acids	Zerex™ G-05™	Ford, Chrysler, European	YELLOW
HOAT (Hybrid OAT, Phosphate-free)	NAP Free	ZEREX™ G-48	BMW, Volvo, Tesla, Mini, others	TURQUOISE
P-HOAT (Phosphated HOAT)	Phosphates & Organic Acids	ZEREX™ Asian Vehicle	Toyota, Nissan, Honda, Hyundai, KIA & other Asian vehicles	PINK / BLUE
Si-OAT (Silicated HOAT)	Silicates & Organic Acids	ZEREX™ G-40	Mercedes-Benz, Audi, VW, Porsche, others	PURPLE

Auto Parts Stores will try to sell you Zerex or Dex-Cool as the OAT for our vehicles, so more misleading & confusion

This video was made by Mopars Training Center

It starts off by stating that Mopar switched to OAT in 2013
I challenge you to stop the video & show me where it reads OAT on the front of the jug

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

i am not sure that the Mopar OAT Coolant has OAT written on the jug anywhere, they just write the MS- *****

They are messing up by making a simple omission

All brands make the customer research the spec & that is not the proper way to do things

 

[crackerjack1957]

MS12106

 

[GTyankee]

We should not have to know that MS number
It should state in bold letters on the jug
MOPAR OAT
MS-12106

Owners manual
Your vehicle has been built with an improved engine coolant (OAT coolant conforming to MS.90032) that allows extended maintenance intervals. This engine coolant (antifreeze) can be used up to ten years or 150,000 miles (240,000 km) before replacement. To prevent reducing this extended maintenance period, it is important that you use the same engine coolant (OAT coolant conforming to MS.90032) throughout the life of your vehicle. Please review these recommendations for using Organic Additive Technology (OAT) engine coolant (antifreeze) that meets the requirements of FCA Material Standard MS.90032. When adding engine coolant (antifreeze): • We recommend using MOPAR Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) that meets the requirements of FCA Material Standard MS.90032.

Antifreeze........such a simple thing.......But can not find MS.90032

I messed up and left my radiator cap loose.....Ugghhh. How did I do that. WTFO! Chrysler Material Standard MS.90032. No problem.......... Problem! Not available in any auto parts store. Online, different MS numbers. Ughhh again. Okay call the dealer, they got it yippeeeeeee. Problem. Not...

I have a coolant question.. HOAT or OAT?
I currently have a 2004 Dodge Durango and 2014 Ram 1500 parked outside.. Both use the 5.7 HEMI V8.
My brother who owns the Dodge says he did some reading and the recommended coolant for his vehicle is HOAT.
I don't know what coolant my dealer uses.. I'm guessing it is the one from Mopar. Right now I don't go to the main dealer, but I follow the maintenance schedule that I downloaded from the Mopar site.

I live in a country where most of the mechanics, don't know or care about the technical specs of the fluids, etc. They will just use what they think is the best, even the main dealers. The main dealer will use the Mopar brand. Now I know the dealer doesn't always care about what is best for my vehicle, they will just push what the products that they have or follow what my chassis number requires. In my experience that led to an issue with my engine. Having said that, the Mopar brand is also rather expensive in comparison to brands like AC Delco.

Dubai often reaches temperatures well over +48.C in the shade during Summer. So what the best coolant for my engine - HOAT or OAT?
And if HOAT is better, what are the brands I should be looking for? Because again as I said, most people don't know about the tech specs of fluids; they don't know HOAT or OAT. I just need to go to a parts store and shop by brand.

HOAT suppose to be good for 5 years & OAT for 10 years.
The 2004 came from factory with HOAT
The 2014 came from factory with OAT
Just flush everything very well & put what you want or have access to in both vehicles then you don't have to worry about what goes where as long as you stay with that brand/type.

Just google coolant chart, no way for us to know what your dealer over there will use, maybe ask them. They stopped using HOAT in 2012 looks like. You can always access your manual by putting Canada and year owners manual in the search bar. My isue with the chart is we don't use dex cool, but a dex clone without the seal killing thing dex has.

Owner's Manual calls for OAT, so presumably our trucks were factory-filled with OAT, and therefore important to remain OAT because articles state OAT and HOAT do not mix, for some reason. They're not chemically compatible. Once a cooling system is filled, it is impossible to drain all coolant out from everywhere. There's always some residual in some areas.

According to articles I read about the difference between OAT & HOAT, HOAT performs better as a hybrid, but needs changing @ 5 years. OAT doesn't inhibit corrosion for the 10 years advertised, so I think that's deceptive.

Therefore, I conclude on changing OAT @ 5 year intervals because our engine blocks are cast iron, subject to rust scaling. I posted on this here ---> https://www.ramforum.com/threads/coolant-change-interval-for-hemi-engines.180241/

No harm is changing it early, pushing the limits it a personal choice. Coolant is cheap.
