Closest equivalent to Mazda's Type FL22 Coolant?

[Number_35]

My 2014 Mazda3 has its 10th birthday this year so I'll be flushing the coolant. The Mazda OEM FL22 premixed is $19 / gallon from MazdaShopUsa. That's not pricey so why look anywhere else? Zerex is only 1 buck cheaper.

Ditto - I buy FL22 from the dealer - it's about the same price as the aftermarket equivalents.

Yo BITOG crew.
I appreciate this thread as I have two Mazdas now with Pentosin A3.
Before it goes stale, might we agree on a definitive list?

Mazda FL22 - P-HOAT - premixed 55/45

Zerex Asian - blue
Peack Original Equipment Asian - green
Pentosin A2 - green and is not premixed
Pentosin A3 - blue, same chemistry as A2 but is 50/50
Ford Specialty Green or Motorcraft Yellow

I would add the OEM brand shown in post #4 of this thread to the list.

Latest list, trying to keep it at the latest of this thread.

Mazda FL22 - P-HOAT - premixed 55/45
==========
Zerex Asian - blue
Peack Original Equipment Asian - green
Pentosin A2 - green and is not premixed
Pentosin A3 - blue, same chemistry as A2 but is 50/50
Ford Specialty Green or Motorcraft Yellow
OEM Extended Life Green

2019 Mazda CX-5 with dealership replaced engine.
The radiator cap says, "FL22".
The coolant reservoir is all but empty.
I can see the coolant is blue.
Would you just choose an acceptable blue coolant or flush clean and start over with a complete refill?

I'd refill the reservoir with Zerex Asian Green (matches whats in my CX5) if it's easy for you to find, or have it go back to the dealer for top-off.

I used Zerex to refill the reservoir in my CX-5 with it a couple of thousand miles ago, and all is well.

I would stick with the FL22 from Mazda or the Motorcraft Specialty Green if its a much better deal.

Why was the engine replaced?

I don't know why it was replaced. That was three years ago this month. We bought the car 30 months ago.
There is no evidence of damage under the car.
The engine in it now runs perfectly.

Would you run the system clean when the engine install reaches 5 years?

It sure seems there are a lot of "silicate and borate free" formulae out there. Is Honda Type2 silicate and borate free?
I'd like to keep it to pale blue until I do the complete job.

Huh, never heard of green ELC before.
All we deal with is red.

It would presumably have Mazda coolant since the dealer did the engine replacement. Its kind if green blue. But its just as likely to be some BG generic coolant.

i can’t recall off hand what interval Mazda recommends, but 5 years seems reasonable. Just drain out all you can. I have not studied ours well enough to see if it has block drains (like on some Toyota engines).
