Specs and approvals listed by the manufacturer

  • Meets Honda Type 2 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (Honda)

Manufacturer wording: Honda owner's manual (2025 Accord): "Specified coolant: Honda Long Life Antifreeze/Coolant Type 2". If Honda coolant is not available, Honda allows "another major brand of non-silicate coolant as a temporary replacement".

"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.

Compatibility notes

  • If your owner's manual calls for Honda Type 2, Honda lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Sold premixed: pour as supplied. Do not add water unless the label says to.

Note: Part number and supersessions from a Honda dealer parts site (Honda Parts Online). Honda does not publish the chemistry name or colour in this manual section.

Always check your owner's manual first. Use the coolant spec printed in your owner's manual or service information. A listing here is the manufacturer's own claim (meets, exceeds, approved or recommended, worded as they put it). It is not our approval and not a fitment guarantee for your vehicle. If in doubt, ask your dealer or a qualified mechanic.
