Specs and approvals listed by the manufacturer
- Meets Mazda FL-22 per Mazda (Mazda)
Manufacturer wording: MazdaShop: "Mazda Warranty Approved". Mazda owner's manual (2022 CX-9): "If the FL22 mark is shown on or near the cooling system cap, use of FL-22 is recommended when replacing engine coolant."
"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 Mazda FL-22, Mazda 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: Pre-diluted at 55% concentration per MazdaShop. Price shown on the store is deliberately not recorded.

FL22 or FL-22: same coolant
Mazda writes it both ways. The owner's manual tells you to look for the "FL22" mark on or near the cooling system cap, and then recommends FL-22 coolant when replacing it, warning that other coolant "may cause serious damage to the engine and cooling system". The bottle, the cap label and the parts listing all refer to the same Mazda coolant.

What color is Mazda FL-22?
Green. A Mazda service bulletin lists part 0000-77-508E-20 as "FL22 Coolant (green)". The same bulletin says FL22 is compatible with Mazda's earlier green ethylene glycol coolant, but that mixing it with orange coolant turns the coolant black, so Mazda says not to mix FL22 and orange coolant. Because green FL22 and green conventional coolant look alike, the cap label is how you tell which one a car needs.

FL-22 equivalents and alternatives
Mazda recommends FL-22 itself where the cap carries the FL22 mark. No other products in our directory list the Mazda FL-22 code, so we cannot name a sourced equivalent. The products below only mention Mazda in their maker's application text. That is the maker's claim, not an approval by Mazda and not a fitment claim by us:
Check your manual, and see the Mazda coolant page for what Mazda publishes.
