Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 eye damage — classified as causing irreversible eye damage on contact.
If splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word DANGER.Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

Translated from the manufacturer’s Safety Data Sheet, Section 2
H318 (serious eye damage Cat 1) is listed in SDS §2. This is the most severe eye hazard classification; serious eye damage is the stated GHS classification.
U.S. regulatory standard
29 CFR 1910.133(a)(1); 1910.151(c)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals, acids or caustic liquids…”
ANSI Z87.1 (chemical splash protection — incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

Translated from the manufacturer’s Safety Data Sheet, Section 2
SDS §2 lists both H317 (skin sensitizer Cat 1) and H315 (skin irritation Cat 2). Per rubric guidance, H317 combined with H315 escalates the skin PPE tier to recommended.
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.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
Especially relevant: in enclosed space
Translated from the ingredient chemistry
H335 (may cause respiratory irritation) appears in SDS §2 at the mixture level, which forces the lungs axis to at least recommended per the chemistry rules. EG vapor pressure is negligible at ambient temperature and no H332/H330/H331 inhalation H-codes are present; risk concentrates in enclosed engine bays or when draining hot coolant.
U.S. regulatory standard
29 CFR 1910.134; 1910.138; 1910.1000
“the primary objective shall be to prevent atmospheric contamination… When effective engineering controls are not feasible… appropriate respirators shall be used.”
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
The published Safety Data Sheet for this product does not specify ventilation protection for consumer use.
Workplace context
29 CFR 1910.134(a); 1910.1000
“the primary objective shall be to prevent atmospheric contamination [via] accepted engineering control measures (for example, enclosure or confinement of the operation, general and local ventilation, and substitution with less toxic materials).”
Triggered by GHS H335 on the SDS.

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.

TL;DR DANGER signal word: H318 serious eye damage means this can cause permanent injury, so wear splash-proof goggles for drain or pour work. Genuine Honda OEM Type 2 extended-life coolant meeting ASTM D3306, formulated for Honda and Acura vehicles requiring the Type 2 spec. Ethylene glycol base; keep secured away from pets and children given the Prop 65 reproductive-toxicity warning.
This is the factory-fill Type 2 coolant sold through Honda's OEM parts channel: a phosphate-buffered hybrid organic acid inhibitor package, pre-mixed 50/50 (label says not to add water). Honda states a 5-year, 60,000-mile service interval, consistent with the HOAT chemistry, though no independent used-coolant analysis confirms that interval in the field. Honda Civic, CR-V, and HRV owners broadly confirm genuine product; counterfeits are a documented OEM-coolant concern.
Best for Honda and Acura owners replacing factory fill or matching a dealership-specified coolant change with a verified OEM Type 2 match. Skip if your vehicle needs Honda Type 1 (older green IAT) or the red Honda HP Coolant spec, or if pet safety matters more; propylene glycol coolant is materially less acutely toxic.
The SDS carries a DANGER signal word from H318 (serious eye damage) and H370 (organ damage); wear splash-proof goggles for drain or pour work. H317 skin sensitizer plus H315 skin irritation calls for nitrile gloves. H335 respiratory irritation means ventilation matters draining hot coolant in an enclosed engine bay. Prop 65 names ethylene glycol a reproductive toxicant via ingestion. Spent coolant belongs in a recycling program, not the storm sewer.
Yes. This is sold through Honda's OEM parts channel (part 08CLA-P99-0F0A8, replacing legacy OL999-9011). owners across multiple Honda models confirm genuine product. Counterfeits exist in the OEM coolant market; purchase from Amazon-fulfilled or Honda-direct sources.
Yes. SDS §3 and the Amazon feature bullets confirm denatonium benzoate at proprietary concentrations above 30 mg/kg. This makes the coolant taste unpleasant to deter accidental ingestion but does not eliminate toxicity. Ethylene glycol carries a DANGER signal word and a Prop 65 reproductive harm warning; keep away from pets and children.
The Type 2 specification applies to Honda and Acura vehicles that require a blue extended-life coolant (non-silicate, phosphate-buffered HOAT formula). Applications include many Honda Civic, CR-V, HRV, and Acura models. Verify your owner's manual before purchasing; Honda also sells Type 1 (green IAT, older models) and HP Coolant (red, some newer models).
Honda states a 5-year / 60,000-mile service interval per the product listing. No independent used-coolant analysis data exists to confirm this interval in field conditions. The phosphate-buffered HOAT inhibitor chemistry is consistent with extended-life claims.
Ethylene glycol (CAS 107-21-1) is on the California Prop 65 list for reproductive toxicity via the ingestion pathway. The back label confirms the warning, and SDS §15 calls this out. This is standard for any ethylene glycol-based automotive coolant sold in California.
