How often you change coolant in a automobile varies from manufacturer to manufacturer. If you have a Toyota you should replace it every two years or 30,000 miles. Everyone keeps trying to convince me its 100% but its not and it can’t ever be. The infrastructure to achieve it is way too expensive. They will just drain the water table. We are not dealing with decent human beings.
