Car radiator fluid is essential for the proper functioning of combustion engines, as it regulates the operating temperature. It prevents engine damage due to excessive or too low temperatures. Learn how using coolant, such as ethylene glycol, prevents freezing and protects your engine. Learn how Mafra radiator fluid protects your engine.

Radiator fluid maintenance

Periodically checking the coolant level in the expansion tank is critical. Follow the directions in your car's Owner's Manual and top off the radiator fluid according to specifications. Check the notches on the container to ensure the correct level.

The check should be done with the car on level ground and with the engine cold, in order to have a correct indication and avoid getting burned by opening the cap. In any case, opening should always be done with caution and by protecting your hands, because pressurized steam may escape from the jar.
