We have had our CX9 since new and it now has about 56k on it. I took it in for a brake flush and they told me it was due for a coolant flush as well according to the mfg. I was OK with it since it endures the Arizona summers and since new from time to time I would get a coolant smell when I shut off the car and got out of it.

Anyway I realized the car has the FL22 and according to the manual it is good for 10 years or roughly 170k. It also states to refill with FL22. The shop I used did not use FL22 as a replacement fluid. Should I be at all concerned over using a non FL22 fluid since it states in the manual to use FL22?
 
Also ask them why they replaced it half way through it's life. What did they use for replacement?
