If you see no obvious leak from the hoses, radiator, water pump,or from the heater core, suspect a blown head gasket. Coolant in the oil, sweet smell at the tail pipe, air bubblesin the radiator, a white foamy substance on the underside of the oil fill cap, missing engine or loss of power, are all signs of a blown head gasket. A compression test will verify this. Caution: Stop drivng if the head gasket is blown. Severe engine damage will occur.
Match the color of your antifreeze to the new one you buy unless it states its good for all types.
Any type of antifreeze will work in a 99 Saturn SL1. Many people recommend using Prestone Antifreeze for cars that are older than ten years.

No vehicle actually burns antifreeze. If the antifreeze level in your Saturn seems to be going down, it's because of a leak.Possible antifreeze leak locations are:Coolant hoses.Radiator cap.Water pump.Heater core.Head gasket.Cracked head or block.Find out where the leak is occurring and repair it.
Dex-cool
The 1997 Saturn used dexcool antifreeze. The chemical compounds are different and should never be mixed, as the engine will no longer cool properly.
To change the antifreeze on a 2003 Saturn Ion-3, locate the drain plug on the bottom of the radiator. Drain the liquid into a pan before refilling it.
Regular antifreeze such as, green, or red!
Anti-freeze that is compatible with aluminium engines.
Use the Gold antifreeze. It lasts longer and does not cause corrosion to the cooling system.
