8 Answers


The normal engine operating temperature on most new GM cars is ~200 degrees. You shouldn't need to add coolant if the car is only a 2007 model, and if you are having problems with your cooling system, they will most likely be covered by your factory warranty. However, to add coolant to the system, you will want to make sure the engine is cool, remove the coolant reservoir cap, and add a blend of 50% water and 50% coolant until it reaches the "Full" mark. Your dealer or auto parts store should be able to tell you which variety of coolant you will need to use.

Point of interest: when adding water/coolant, be sure to use distilled water as tap water will introduce mineral deposits into your radiator and facilitate cooling failure.

My 07 Cobalt LT sedan always runs at 93 degrees Celsius, regardless of outside temperature. might just be my temperature gauge malfunctioning.
