What coolant does Chrysler, Jeep, Ram & Dodge use?
Chrysler, Jeep, Ram and Dodge coolant: recent Mopar manuals specify OAT coolant to MS.90032, and Mopar sells it as 10-Year/150,000-Mile OAT (concentrate MS-90032, 50/50 MS-12106). Mopar says not to mix it with HOAT or "globally compatible" coolant. Other vehicles may specify MS-9769, so check yours.
- The 2022 Ram 2500/3500 owner's manual specifies Organic Additive Technology (OAT) coolant "conforming to MS.90032". It warns that OAT "should not be mixed with Hybrid Organic Additive Technology (HOAT) engine coolant or any 'globally compatible' coolant". [1]
- The same manual says the vehicle "has not been designed for use with propylene glycol-based engine coolant". [1]
- Mopar's 2026 catalog lists 10-Year/150,000-Mile OAT coolant as concentrate to MS-90032 (68163848AB) and 50/50 prediluted to MS-12106 (68163849AB), and calls the two interchangeable. [2]
- The Mopar eStore describes 68163848AC as "OAT Concentrate. Standard MS-9769", which differs from the catalog. Coolant makers list MS-9769 on HOAT products such as Zerex G05, so check the standard printed in your manual. [3]

Coolants that list a Chrysler, Jeep, Ram & Dodge spec (per their manufacturer)
Each row reads "meets [code] per [brand]". The wording ("approved", "meets or exceeds", "recommended") is quoted on the product page. Open it before you buy.
Coolants whose maker names Chrysler, Jeep, Ram & Dodge (guidance only)
These products do not list a Chrysler, Jeep, Ram & Dodge spec code, but their manufacturer's application text names Chrysler, Jeep, Ram & Dodge (for example "recommended for Toyota, Honda, Nissan…"). That is a weaker claim than a spec code. Treat it as guidance, check the exact wording, and follow your manual.

Not sure which coolant your car takes?
Find your coolant →Colour and chemistry
Among the 28 products on this page, the listed colours are Orange (5), Green (3), Purple (3), Yellow (2), Gold (2), Blue (2), and the listed chemistries are OAT (11), IAT (6), HOAT (5). Colour is a dye chosen by each maker, so two coolants of the same colour can be chemically different, and the same chemistry can come in different colours. Match the spec or the named factory coolant, not the colour. See coolant colours explained and OAT vs HOAT vs IAT.
Topping up and mixing
If the reservoir is low, top up only with the coolant your manual specifies, and use the same premix or concentrate ratio. Mixing chemistries can reduce corrosion protection and shorten coolant life. Some makers (Mopar, Mercedes-Benz) explicitly say not to mix specs. If an unknown coolant has been added, a flush and refill is safer than topping up. Use the mixing checker and our coolant flush guide. Never open a hot radiator or reservoir cap.
Varies by model and year
Chrysler, Jeep, Ram & Dodge has changed coolant specs over the years, and a spec can differ by engine and market (for example North America vs Europe). Electric and hybrid models may use separate loops with their own fluids. This page does not tell you which code applies to your vehicle. Your owner's manual, the reservoir cap label or a dealer does.
When to see a mechanic
See a dealer or qualified mechanic if the coolant looks rusty, oily or sludgy, if the engine overheats or the coolant warning light comes on, or if you cannot identify the correct spec. See coolant warning light and coolant leaks.
