Why Antifreeze is Key
Antifreeze/coolant is a big part of what keeps your engine in top working order. In addition to its cooling properties and ability to keep your engine running under extreme temperature variations, many companies also include other ingredients that help keep your engine working well. For instance, antifreeze can contain additives that prevent rust and corrosion of the radiator, engine and vehicle heater. If you neglect radiator maintenance the advantages of a good cooling system will not be fully utilized.

Draining and Flushing
Over time, rust and sediment can build up in your vehicle’s cooling system making it necessary to drain out the coolant from time to time to clean out anything that may be clogging up the system. Many experts recommend this be done every few years, preferably every year. You can tell if the coolant in your radiator requires removal if it appears dirty or brown in color, and if you see little rust specks floating around. Coolant should appear a slightly thick, light yellowy-green color, almost like lemonade, or orange if your car uses long-lasting coolant.
