Gen3 Coolant

[djevox]

From the manual
"The engine cooling system must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. OAT coolant (conforming to MS.90032) is recommended."
Finding the MS.90032 was difficult.

That link to Auto Zone comes up as "fits your vehicle" for my 2019 Ram. Bad info on Auto Zone's part. That is HOAT which would cause problems if mixed with OAT.

I didn't link to prestone's site because they have minimal info, but that variation I showed there is actually an OAT coolant. Prestone claims they are compatible with HOAT as well. The question really is if they can be trusted, but I'd think that would be a big liability if they were wrong. (assuming someone could prove it, of course)

Anybody out there with a 2019 that has the anti freeze label?
Or
Who has a label and who doesn't?
The label sure makes things easy vs my 2019 owner's manual.

Do you have a Ram classic with the ecodiesel? I'm confused.

That is what was given to me by the dealership for my 2019 Bighorn Hemi. I do not know what an eco diesel would take and would not make any assumptions as I am not qualified.

I have a leftover gallon of coolant the dealership sold me for my Jeep's Gen2 EcoDiesel. Is it appropriate for my Ram's Gen3 EcoDiesel?

The part # is MS-12106.

I checked the manual and it only said "We recommend you use Mopar® Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km) Formula OAT (Organic Additive Technology)."

EDIT: This gallon does reference "Organic Additive Technology" in the description on the back.

Hi, I’m fixing to change my coolant on my 3rd gen have any of you guys had a chance to do it ? I don’t want to take it in the dealership, do you guys know of a video that shows me how to change it ? Is there any special tools I need to refill? Or even to drain the whole system

I'm a big believer in early fluid changes. Yeah...100,000 mile/10 year coolant interval is what Mopar says. Other than cooling (and preventing freezing and boil over), coolant has sacrificial anode dissolved in it. Like the zinc block on a boat, it prevents the other metal from rotting and corroding. You know, stuff like aluminum and iron, etc. So, I change mine out every 2-3 years (or 4... Shrug.).

The drain plug on these trucks is a plastic "nut". It's more than just a nut. Here's a pic:





That's a spare. I bought 2 spares, in case I broke the installed one. (Plastic...
