From the manufacturer’s Safety Data Sheet, Section 8
“H319 (eye irritation Cat 2) is classified at concentrate level; the back-of-bottle label confirms eye irritation. During drain work or coolant transfer, splash contact is plausible. No H318 (serious eye damage) — not required for routine pour-fill.”

From the manufacturer’s Safety Data Sheet, Section 8
“H315 (skin irritation) is classified at concentrate and 50/50 levels. SDS §8 specifies protective gloves where skin contact is possible; back label confirms 'causes skin irritation.' Brief pour-fill contact is low risk; drain and flush work carries the same H315-classified chemistry.”

CarCareTruth's Analysis
Last reviewed May 26, 2026
TL;DR The OEM factory-fill formula for FCA/Stellantis vehicles (Chrysler, Dodge, Jeep, Ram, Alfa Romeo) — meets MS-90032 and ASTM D3306 Type 3. OAT inhibitor, silicate-free, 10-year/150,000-mile interval. Ethylene glycol base — H302 (harmful if swallowed) applies; keep away from pets and children or consider a propylene glycol alternative.
What it is and how it performs
Mopar 68163849AB is the first-party OEM coolant for FCA/Stellantis vehicles requiring MS-90032 — 2013-and-newer Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo applications. OAT (Organic Acid Technology) inhibitor is phosphate-free and silicate-free, with a 10-year/150,000-mile label claim consistent with OAT chemistry. Meets ASTM D3306 Type 3. Premixed 50/50 — do not add water. Ethylene glycol base with denatonium benzoate bittering deterrent added; store securely away from pets and children due to the ethylene glycol ingestion hazard.
Who should buy this — and who should skip it
Best for 2013+ FCA/Stellantis owners whose manual requires MS-90032 — the spec reference product, rated 4.8 stars from 6,000+ reviews. Skip for non-FCA vehicles (GM, Ford, Toyota, Honda, VW, BMW each require different coolant chemistry) or if you want concentrate for ratio control.
Safety and environmental impact
The SDS (rev 04/15/2024) carries signal word WARNING with H302 (harmful if swallowed, Cat 4), H361 (suspected reproductive toxicant), and H373 (prolonged organ exposure) — ethylene glycol base. Prop 65 reproductive harm listing applies. SDS §8 specifies gloves and eye protection during drain or pour work; no respirator required at ambient temperatures. Collect spent coolant for recycling at auto parts stores — do not drain to ground or storm sewer.
Frequently asked questions
What vehicles is Mopar OAT coolant compatible with?▾
It's the OEM-specified coolant for most FCA/Stellantis vehicles from 2013 onward — Chrysler, Dodge, Jeep, Ram, Alfa Romeo, and FIAT applications that call for MS-90032 OAT coolant. Always verify against your owner's manual before filling. Do not mix with IAT (green silicate) coolant or HOAT formulas without a complete system flush.
Does this need to be diluted with water?▾
No. This is the 50/50 premixed version — it's ready to pour in directly as labeled 'DO NOT ADD WATER.' A separate concentrate version (part 68163848) is also available for owners who prefer to mix their own ratio.
Is this coolant safe around pets?▾
The formula is embittered — it contains denatonium benzoate, a bittering agent added specifically to reduce accidental ingestion palatability for pets and children. That said, the H302 classification (harmful if swallowed) from ethylene glycol still applies. The bitterant reduces the risk of voluntary consumption but does not change the toxicity of the substance itself. Store coolant securely and clean up spills immediately.
Is this a CARB-compliant product?▾
VOC content is not disclosed in the available SDS, so no CARB-compliant claim can be made. Ethylene glycol is a low-VOC glycol at these concentrations, but without a disclosed VOC measurement from the SDS or TDS, the carb_compliant flag is not set.
