There is no information on the Mazda3 service schedule regarding coolant.

Car is at 125,000km and 5+ years old.

I've had the original coolant flushed out about 2.5 years ago. Got it done at Avante Mazda so I am going to say they used the stock coolant.

That was well over 60,000km+ ago.

Is it time again? If so, what brand of coolant should be I be getting? Should I just stick with the Mazda stock coolant?
