Coolant warning light on, coolant level close to or below minimum. The customer had to top off the coolant several times. Air gets into the cooling system during production or when refilled during previous repairs. As this air escapes, the coolant level in the coolant expansion tank can drop below the minimum. A drop of the coolant level because of air in the system is possible even after the vehicle has exceeded 15,000 miles. Because of the remaining air, the coolant level can drop a few times.
