Replace your coolant: CX-5 CX-3 Mazda3 Mazda6

This information may be elsewhere in this forum. But, since I recently replaced a CX-9 water pump I was forced to become more knowledgeable about the FL22 coolant and options.
For future readers here are the options that are currently available for FL22 coolant:
OEM diluted Mazda part#: 0000-77-508E-20
Mazda has a concentrate formula OEM: 0000-77-501E-02 but this can be tougher to find and appears on some sites to be discontinued.
Ford (Motorcraft)diluted version: VC-10-A
Ford (Motorcraft) concentrate: VC-10-A2 (specialty green)
There are aftermarket options from Ravenol and Pentosin (and Zerex if you don*t care about the resulting color of the mix):
Ravenol is available in both diluted and concentrate:
Diluted: Ravenol J4D2091-1-10 HJC FL22
Concentrate: Ravenol J4D2091-10 HJC FL22
Pentosin Pentofrost A2 is a dark green concentrate that must be mixed with water. 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.
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. And, as far as I am aware, the Zerex Asian vehicle formulas are only available as diluted.
Not 100% sure about the Ford coolants, but I'm fairly certain that 0000-77-501E-02 is NOT FL-22, but the "1st gen" long life coolant that Mazda was using for a while. This chart seems to back that up: 49024155578_8f7b6623b7_o.png

I believe that Pentofrost A2 is also equivalent to 0000-77-501E-02 (i.e. not FL-22), since it references the 501E part number, and their antifreeze guide states that A2 should be not used in Mazdas 2006 and newer : http://www.pentosin.net/literature/Pentosin Pentofrost Antifreeze Guide.pdf

Ravenol appears to be FL-22 as far as I can tell and, as I said, no idea which category the Motorcraft coolants fall under.

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. But, these first generation Japanese P-HOAT coolants contain all the same main ingredients and are silicate free formulas, completely compatible with FL22. Mazda will tell you to put FL22 in a car with Mazda Long Life. If you dilute these first gen Japanese P-HOAT coolants with distilled water I’m confident that you will NOT compromise the life of your Mazda engine, water pump and radiator-but you probably should drain at 60K versus 120K for the FL22.

Ravenol Hybrid Japanese Coolant diluted and concentrate both explicitly claim FL22 - and I believe them.
The Motorcraft specialty green = Ford VC-10-A2 and Ford coolant spec is also listed on the Ravenol HJC packaging. Also, Ford VC-10-A2 is explicitly used in the Ford Edge and Flex at the same time FL22 appeared in the first gen CX-9. So, for me at least, Ravenol and Ford VC-10-A2 pass as exact substitutes for FL22 in a concentrate form.
The Toyota Super Long Life Coolant and Honda Type 2 (Asian Pink and Blue) are also second gen P-HOAT = FL22, but different colors. Be thankful we have some concentrate substitutes that match our dark green pixie dust coolant.

I guess I’ll just get genuine Mazda OEM FL-22 coolant and be done with it. I’m not going to try to figure out the compatibility issue among many other different types of FL-22 coolant.

It’s worth to mention that the recommended coolant change interval is shortened to a half after the first replacement at 120K miles or 10 years:

Replace at first 192,000 km (120,000 miles) or 10 years; after that, every 96,000 km (60,000 miles) or 5 years.

Any of these would work.....same compatible stuff but in different colors to match year/make of OEM color. In other words get the green one if you have a Mazda.

I used the Valvoline Asian formula in my old Mazda from the time it was new for 12 years.

Fantastic to see Peak Asian green. I'm sure over time others will follow - but it is clear that the automakers and the aftermarket coolant makers don't trust the DIY market to use de-ionized or distilled water for mixing. Ravenol and Motorcraft are the only sources (not even Mazda) to offer a concentrate for FL22 - crazy

Probably more like they want to charge $5 for 10c worth of distilled water :(

When I got the water pump replaced for Mazda 6, my mechanic actually hooked up the radiator to a machine to flush out OEM green stuff (plus any contaminants) and replace with PEAK Asian Blue. He mistakenly bought the wrong color but I'm "cool" with it. Same stuff different dye.

Agree. If you DIY it's not as easy to recover without the flush machine - and to get the water to coolant mix correct without an option for adding a concentrated version. But, 4-5 drain and refill cycles will get you there even if you only have the pre-diluted coolant.

I have 70K miles on my 2016 CX-5. So far, I have replaced the brake fluid and ATF. The dealer recommended coolant flush during next service at 75K miles. Does this make sense?

What is the recommended mileage and frequency for coolant flush?

Any other fluids I should change at 75K miles?

Nope. Check your owners manual. It’s likely not due until 10 years or 120k miles. 5 years and 60k miles after that.
