Report: Coolant Loss Due to Leak from Expansion Tank
BMW 528i Problem
Average Mileage: 130,000 mi (120,000 mi - 140,000 mi)
An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.
Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.
The impeller in the water pump is known to break or fall. This lead to the radiator and coolant reservoir to fail as well.
