GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

H319 (serious eye irritation) at SDS §2 mixture level.

“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”
ANSI Z87.1 (incorporated via §1910.6)

Especially relevant: prolonged use · splash risk

H315 (skin irritation) at SDS §2 mixture level.
U.S. regulatory standard
29 CFR 1910.138(a)
“appropriate hand protection when employees' hands are exposed to hazards such as those from… chemicals which produce an adverse effect on the skin or eyes…”
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

Only when: in enclosed space
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS §8 states 'Local exhaust ventilation usually required. If risk of overexposure exists, wear approved respirator,' and names a Type A-P filter half-face or full-face respirator selection table. No H330, H331, H334, or H335 in SDS §2 mixture classification, and EG vapor pressure is negligible at ambient temperature. The named respirator control is a cautious precaution for drain-and-flush work in an enclosed garage, not a documented mixture-level inhalation-hazard classification.
U.S. regulatory standard
29 CFR 1910.134; 1910.138; 1910.1000
“the primary objective shall be to prevent atmospheric contamination…”
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

H373“May cause damage to organs through prolonged or repeated exposure”
UN GHS Rev. 9 (2021)

No PPE specified in published sources for ventilation. Absence does not imply “not needed” — consult the full Safety Data Sheet.
PPE tiers translate the manufacturer’s SDS and U.S. regulatory standards. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.
No warranties. CarCareTruth makes no warranties, express or implied, and expressly disclaims the implied warranties of merchantability and fitness for a particular purpose.

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.
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.
Best for 2013+ FCA/Stellantis owners whose manual requires MS-90032 · the spec reference product, highly rated and broadly trusted by owners. Skip for non-FCA vehicles (GM, Ford, Toyota, Honda, VW, BMW each require different coolant chemistry) or if you want concentrate for ratio control.
The SDS (rev 04/15/2024) carries signal word WARNING with H302 (harmful if swallowed), H315 (skin irritation), H319 (eye irritation), 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 for drain, flush, or pour work; a respirator is a situational precaution for enclosed, poorly ventilated garages only. Collect spent coolant for recycling at auto parts stores · do not drain to ground or storm sewer.
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.
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.
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.
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.
The listing for Mopar OAT 10 Year/150,000 Mile Coolant 50/50 Premixed carries a California Prop 65 warning. Mopar OAT 10 Year/150,000 Mile Coolant 50/50 Premixed is a working automotive fluid rather than a passive part, so the warning points at the formulation itself. The manufacturer's Safety Data Sheet is the primary source for what is in it: the hazard classification and the PPE tiers on this page are translated from that sheet, and the full SDS is linked from the safety panel. California requires the warning whenever exposure to any of roughly 900 listed substances is possible. It does not name which substance applies to a given product, and it states no dose or risk level, so it is not on its own a measure of how hazardous this fluid is in normal use.
