The 2009 Chevy Cobalt uses Dex-cool Extended Life 50/50 antifreeze engine coolant. It has a capacity of about 6.3 quarts. Coolant is used to transfer heat which can assist in preventing engine damage caused by freezing or boiling. Coolant can also protect various metal and non-metallic parts in the engine and the cooling circuit. The cost of getting the coolant changed on your Cobalt is between $130 and $160. You should get a coolant change every 5,000 miles. If you notice that the temperature gauge is always high or that the engine is frequently overheating, then these are signs that your vehicle needs a coolant flush and it's best to have it done before it will lead to more serious and costly problems.
