Comma coolant at a glance

Independent; not affiliated with or endorsed by Comma. Coolant.com is an independent reference. Comma is named only to identify its products, as the owner of the name. We use no logos and earn nothing from links. Every product detail below is copied from Comma's own pages or data sheets, or from the source named on each product page, checked 22 October 2026. "Not published" means the source does not state it.

Comma products in this directory are made or sold by Comma. We list 7 of them, 7 car/light-vehicle. Listed chemistries: OAT (4), Si-OAT (2), IAT (1). Listed colours: not published (7). 7 of 7 state a service life, and 0 make a "free of" claim (for example silicate-free or nitrite-free).

These counts describe what Comma 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 Comma lists

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

  • OAT (4 products): Organic Acid Technology: carboxylate inhibitors, normally silicate- and phosphate-free, used for long service intervals. GM Dex-Cool-type and Ford orange coolants are examples of OAT families.
  • Si-OAT (2 products): Silicated OAT: organic acids with a little silicate. It is the family behind VW TL 774-G (G12++) and similar European specs.
  • IAT (1 product): Inorganic Additive Technology: the traditional silicate- and phosphate-based "green" coolant with shorter change intervals.

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 Comma lists

These are the OEM and industry spec codes Comma lists across its products. Each one reads as "meets [code] per Comma". 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 Comma 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 Comma 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. Comma lists 4 concentrate and 3 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?

Where to buy Comma coolant

7 of 7 Comma product pages here carry retailer links. These are the links Comma itself shows on its product page, or its official parts store. We add none of our own, and they are not affiliate links. Many retailers block automated checks, so each link is labelled with its check status. We do not show prices.

When to see a mechanic

If you are not sure which coolant your vehicle needs, if the system has been topped up with an unknown coolant, or if you see overheating, coolant loss or a sweet smell, see a qualified mechanic or dealer. See coolant leaks.
