Honda coolant: products, specs and approvals

Confirm the specification in your owner’s manual before buying. Product examples are not a fitment guarantee.

Honda coolant at a glance

Honda products in this directory are made or sold by American Honda Motor Co.. We list 1 of them, 1 car/light-vehicle. Listed chemistries: not published (1). Listed colours: not published (1). 0 of 1 state a service life, and 0 make a "free of" claim (for example silicate-free or nitrite-free).

These counts describe what Honda publishes, not how good a product is. A product with no listed spec codes may still meet them. It means the manufacturer did not print them on the page we checked.

Chemistries Honda lists

Chemistry is the inhibitor family that protects the metals in a cooling system. Here is what Honda names across its products, with a short explanation of each family:

• not published (1 product): The manufacturer does not name the inhibitor technology on the source we checked.

Two products in the same family are not always interchangeable, because additive levels and approvals differ. See OAT vs HOAT vs IAT and G11, G12, G13 and G48.

Specs and approvals Honda lists

These are the OEM and industry spec codes Honda lists across its products. Each one reads as "meets [code] per Honda". The manufacturer's own wording ("approved", "meets or exceeds", "recommended for") is quoted on each product page. A listing is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker unless the wording says so.

How to choose a Honda coolant

1. Find the spec in your owner's manual (or the label on the coolant reservoir cap). It may be a code such as WSS-M97B44-D, GMW 3420, MS-12106, TL 774-G or MB 325.0, or a named factory coolant.
2. Check whether Honda lists that exact code. Use the table above, or type the code into Find my car coolant. Letter suffixes matter: TL 774-G is not TL 774-J.
3. Open the product page and read the wording. "Approved" is stronger than "meets or exceeds", and both are stronger than "recommended for vehicles requiring".
4. Choose premix or concentrate. Honda lists 0 concentrate and 1 premix products here (some are sold both ways). Premix avoids mixing errors; concentrate must be diluted with distilled or deionised water. See premix vs concentrate.
5. Do not mix chemistries. If the system already holds a different coolant, check the mixing checker or flush first. See can you mix coolant?

What Honda does not publish (on the sources we checked)

We do not fill gaps with guesses. Where Honda's page or sheet leaves a field out, we mark it "not published":

• chemistry: not published for 1 of 1
• colour: not published for 1 of 1
• freeze point: not published for 0 of 1
• service life: not published for 1 of 1
• data sheet link: not published for 1 of 1

The bottle label, the full data sheet or Honda's technical helpline may give more detail.

Where to buy Honda coolant

0 of 1 Honda product pages here carry retailer links. These are the links Honda itself shows on its product page, or its official parts store. Where a product has a verified Amazon listing we also show an Amazon link, which is an affiliate link (we may earn a commission). Other links are not affiliate links. Many retailers block automated checks, so each link is labelled with its check status. We do not show prices.

Compare with other coolant brands

Honda is the genuine coolant line for Honda vehicles. What Honda specifies by model and year, with citations, is on the Honda coolant page.

Brand matters less than the spec code. If Honda does not list the code in your manual, check whether Hyundai, Fleetguard, Kia or febi does, or search every product at once in Find my car coolant. The full list is in the coolant brands index.
