perfectly works for my GLE 350 2024
Works with my 2024 GLE350. It's concentrated, so you have to get distilled water from CVS, get a new cup, and add one cup of coolant and one cup of distilled water to make sure it's 50:50. and the warning signal goes away immediately.

This is Concentrated solution
Great deal since it's a concentrate, otherwise I would have had to spent twice as much if I bought the pre-diluted since my car takes a half gallon more than the amount in the container. This way I will have enough for two mercedes.
