Honda Extended Life Antifreeze/Coolant Type 2

This is the factory-fill Type 2 coolant sold through Honda's OEM parts channel, using a phosphate-buffered hybrid organic acid inhibitor package and pre-mixed 50/50 · the label says not to add water. Honda states a 5-year / 60,000-mile service interval, consistent with the HOAT inhibitor chemistry, though no independent used-coolant analysis corroborates that drain interval in the field. owner reviews from Honda Civic, CR-V, and HRV owners broadly confirm genuine product; counterfeits are a documented concern in OEM coolant. Ethylene glycol base · not a propylene glycol alternative if household pet safety is the priority.

Best for Honda and Acura owners replacing factory fill or following a dealership-specified coolant change who want a verified OEM Type 2 match. Skip if your vehicle requires Honda Type 1 (the older green IAT formula for pre-2002 models) or a red Honda HP Coolant spec. Skip also if pet safety is the primary concern · a propylene glycol-based coolant carries materially lower acute toxicity for incidental ingestion.

The SDS carries a DANGER signal word driven by H318 (serious eye damage Cat 1) and H370 (causes organ damage · central nervous system and kidneys). H317 (skin sensitizer Cat 1) combined with H315 (skin irritation Cat 2) means nitrile gloves are indicated for drain or extended contact work · H317 escalates the skin tier beyond simple irritation. H335 (respiratory irritation) appears in SDS §2 but inhalation risk is negligible at ambient temperatures given EG's very low vapor pressure; the enclosed_space situational designation applies when draining hot coolant. The Prop 65 warning on the back label and in SDS §15 identifies ethylene glycol as a reproductive toxicant via the ingestion route. Spent coolant must be collected and taken to an auto parts store recycling program · not drained to the ground or storm sewer.
