Im assuming the blue colored anti-freeze in my '22 is a HOAT type of fluid? Ive noticed the expansion tank level has always been right at or slightly below the min fill line when the engine is cold. I want to top it up.

ha, i need to call the dealer to order some myself. It's on my list of things to do this week. I have the same issue as you. The owners manual states what fluid to use, which is a little confusing cause when you read it, it sounds like a generic thing, but the generic sounding name is the actual mopar name of the product.

Interesting I noticed the same, just under the minimum line.

MS.90032 OAT Concentrate PN: 68163848AB

The manual states the MS.90032, which is their own internal standard. There's also a 50/50 premix of the same stuff which attributes a different standard to it. I don't know what that number is off hand. It looks to be the one that @rharr posted above.

My local dealership had the concentrate on hand for $24 a gallon.

It's purple, by the way.

That is the stuff the dealer gave me as well. Thanks for saving me from posting my photo.

Thanks for the insight, actually, looking at it this morning, it does look light purple. They are proud of it! I would use another compatible brand, but I dont want anything to mess with the warranty or give them a reason to nay-nay if a claim comes up.
