Manufacturer approvals for the coolant.

Cars from different manufacturers may have different specific features that cannot be taken into account in generally accepted standards.

These standards are called tolerances, they are usually indicated in the official documentation for the machine.

It is best to use brands of coolant that correspond to this tolerance — they are best suited for this car model.
