Chemistries Subaru lists

Chemistry is the inhibitor family that protects the metals in a cooling system. Here is what Subaru 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 Subaru lists

The Subaru sources we checked list no OEM or industry spec codes. That is common for genuine vehicle-maker coolants, which are identified by part number and specified by name in the owner's manual. Check the label or your manual for the exact designation.

How to choose a Subaru coolant

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.
Check whether Subaru 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.
Open the product page and read the wording. "Approved" is stronger than "meets or exceeds", and both are stronger than "recommended for vehicles requiring".
Choose premix or concentrate. Subaru 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.
Do not mix chemistries. If the system already holds a different coolant, check the mixing checker or flush first. See can you mix coolant?
