2009 - 2012 should have 50% HOAT in the Coolant system
Draw fluid out of the radiator & look at the color in clear jar, in the Daylight
Now just forget about color, different manufacturers use different colors for the same antifreeze type.
What color coolant does Chrysler use?
It's critical to understand that color doesn't matter.
While most Organic Acid Technology (OAT) coolants are normally orange, yellow, red or purple, Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow.
So evidently, there's quite a bit of overlap. Then you have Inorganic Acid Technology (IAT) coolants that are normally green, yet, some manufacturers sell them in blue.
At the end of the day, consistently be sure to read the bottle to confirm the type of coolant you're utilizing.

The purpose of this thread isn't to start a debate about anti-freeze. I simply wanted to pass on some info I learned today from a tech at Valvoline.
The other day I noticed some sediment buildup in the bottom of my overflow reservoir. So today I took it out and cleaned it. I had some leftover Zerex G-05 HOAT antifreeze, which up thru 2012 was the Chrysler specified antifreeze.
I wondered if the sediment came from the factory HOAT so I placed a call to Valvoline and spoke to one of their antifreeze techs, named Ronnie. Here's what I learned.
1) Valvoline makes the HOAT for Chrysler. Zerex gets a yellow dye while the Mopar version gets a pinkish dye. Chrysler buys the stuff in bulk. Automakers have been known to throw stuff in the mix to help prolong the life of rubber hoses or lubricate the water pump. This is a common cause of sediment drop out in overflow tanks.
Then the same guy, was incorrect when he wrote;
2) The Mopar OAT for 2013 and newer (which is expensive as hell from the dealer) is the same as the latest Dexcool.
(( this is a complete inaccuracy, that comes from Valvoline, they are irritated that the did not get the OAT Coolant contract from Chrysler, FCA, & now Stellantis ))
