Hello,

I have to flush my car antifreeze.
I'm really lost with the antifreeze choice. It seems to be a green one for my car listed above. Is that correct? Any alternative? The norm seems to be GM1825M, any other one with no risk?
Thanks for helping.
By the way, i live in France...

Good morning,

Refill the cooling system with a coolant meeting GM Specification 1825-M. To ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at -37°C (34°F) or lower. Use a solution that is no more than 70 percent antifreeze.

The 1825 is what is recommended but there is a coolant for all makes, all models that is acceptable as well. I do not know if it is available in France for you but here in the USA it is good to mix with it.
