Coolant Change

The radiator fluid is perhaps the most vital part of your car's cooling system. The radiator fluid, or antifreeze coolant, is the liquid mixture of antifreeze and water that runs throughout your car's cooling system and helps keep your car engine cool while running. It also helps to keep the engine block from freezing in extreme cold temperatures when the vehicle is parked.

Periodically Change Your Car's Radiator Fluid

You should periodically change the radiator fluid in your vehicle to help your car's cooling system function at its best. Over time, dirt and other contaminants can build up in the fluid, or it may become acidic. When this occurs, the radiator fluid is much less effective and should be changed.
