Coolant product directory

Updated 22 October 2026 · Independent, sourced reference

Quick answer

This directory lists 137 coolant products from 25 brands. Each one has its chemistry, colour, premix or concentrate form, the OEM spec codes the manufacturer lists, and its service-life claim, all taken from the manufacturer's own page or datasheet. Filter by brand, chemistry or colour, or search for the spec code in your owner's manual.

Disclaimer: General information only, not professional advice. Always use the coolant specified in your vehicle owner's manual. Using the wrong coolant can damage an engine.

Key takeaways

  • Every field is sourced from the manufacturer. Anything we could not find is marked "not published".
  • 84 of 137 products have at least one OEM or industry spec code listed by their maker.
  • Search by the spec code in your owner's manual, not by colour.
  • No prices, ratings or rankings. The table is sorted by brand.
  • Use Compare coolants to see up to four side by side.

How to use this directory

Start with your owner's manual. Most manuals name a coolant spec code (for example Ford WSS-M97B44-D, GM 6277M, Chrysler MS-12106, VW TL 774-G or Mercedes-Benz 325.0) or a named factory coolant (such as Toyota Super Long Life Coolant or Honda Type 2). Type that code into the search box, and the table narrows to the products whose manufacturer lists it. Then open a product page to read the manufacturer's exact wording. "Meets or exceeds", "approved" and "recommended for applications requiring" are not the same thing, and we show which one applies.

If your manual gives only a colour or a general type, use the chemistry filter as a starting point, and read our guide to OAT, HOAT and IAT chemistries. Colour alone is not a reliable guide, because dyes vary by brand and region.

What each column means

FieldWhat it shows
ChemistryThe inhibitor technology the manufacturer names: IAT (conventional), OAT, HOAT, P-OAT (phosphate-enhanced OAT), Si-OAT (silicated OAT) or P-Si-OAT. Universal products that only say they are "compatible with all types" are marked not published.
ColourThe dye colour as named on the product or datasheet.
FormConcentrate (dilute before use) or premix 50/50 (ready to use). Some product pages cover both forms.
Specs listedHow many OEM or industry spec codes the manufacturer lists. Open the product to see each code and the exact wording.

Coverage and method

We collected products from manufacturer websites and datasheets on 22 October 2026. Car brands come first, followed by heavy-duty and data-center fluids. Counts by brand: ACDelco 7, Arteco 1, BASF 1, Castrol 5, Comma 7, Fleetguard 1, Honda 1, Hyundai 1, Kia 1, Mazda 1, Mobil 1, Mopar 2, Motorcraft 1, Nissan 1, PEAK 36, Prestone 22, Recochem 32, Shell 3, Subaru 1, Tesla 1, Toyota 1, Valvoline 1, Volkswagen 1, Zerex 7, febi 1. Concentrate and 50/50 versions with separate manufacturer pages and part numbers are listed separately.

Fields are copied from the source text. Spec codes are normalised for search (for example "GM-6277M" becomes "GM 6277M"), but the meaning is not changed. Where a manufacturer's page blocks automated checks, we read it with a fetch tool and say so on the product page. We do not record prices, because they change constantly and differ by store. The whole dataset can be downloaded as JSON or CSV.

Known gaps

Some major brands are not yet covered or have only one entry. Their sites either load product data with scripts we could not read reliably or block automated access: Valvoline/Zerex, Motorcraft (one product), Mopar (one product), Toyota (part number only), Honda, BMW, Mercedes-Benz, Volkswagen genuine, Shell car coolants, Mobil and Old World's other brands. We will add them only when we can cite the manufacturer directly. Prestone's vehicle-specific product pages do not list spec codes, so those entries show "not published" for specs even though the bottle label may carry them.

When to see a mechanic

If you are unsure which coolant your car needs, if the cooling system has been topped up with an unknown coolant, or if you see overheating, coolant loss or a sweet smell, have a qualified mechanic or dealer check it. See coolant leaks and coolant warning light.

Frequently asked questions

Is this a ranking of the best coolant?

No. The directory is sorted by brand, and we do not rate or rank products. The right coolant is the one that meets the spec in your owner's manual.

Why do some products say "not published"?

Because the manufacturer page or datasheet we checked did not state that field. We do not guess. The bottle label or the manufacturer's technical service line may have more detail.

Are the buy links affiliate links?

No. Retailer links are the ones the manufacturer itself shows on its product page, or its official parts store. Coolant.com earns nothing from them.

Can I download the data?

Yes. The full dataset is at /data/coolants.json and /data/coolants.csv, with a source link and check date for every product.
