Mazda will tell you to put FL22 in a car with Mazda Long Life.
TOYOTA SUPER LONG LIFE COOLANT PENTOSIN FREE
But, these first generation Japanese P-HOAT coolants contain all the same main ingredients and are silicate free formulas, completely compatible with FL22.

Reluctantly I agree that Mazda Long Life Coolant concentrate (501E) and the Pentosin A2 are first generation phosphate HOAT formulas that do not have the exact FL22 additive package. And, as far as I am aware, the Zerex Asian vehicle formulas are only available as diluted. The Zerex Asian formulas are also compatible and likely the same chemistry * but the color can be a challenge (blue or pink) unless you do a complete change. The nice thing about Pentofrost A2 is that it is available at some auto part stores and Rockauto for a much better price compared to most of the options above. Pentosin Pentofrost A2 is a dark green concentrate that must be mixed with water. Ravenol is available in both diluted and concentrate:

There are aftermarket options from Ravenol and Pentosin (and Zerex if you don*t care about the resulting color of the mix):

Mazda has a concentrate formula OEM: 1E-02 but this can be tougher to find and appears on some sites to be discontinued.įord (Motorcraft)diluted version: VC-10-Aįord (Motorcraft) concentrate: VC-10-A2 (specialty green) But, since I recently replaced a CX-9 water pump I was forced to become more knowledgeable about the FL22 coolant and options.įor future readers here are the options that are currently available for FL22 coolant: This information may be elsewhere in this forum.
