The most common reasons a 2014 BMW 528i xDrive is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
  • Thermostat: A faulty thermostat can cause the engine to overheat or run too cool by failing to regulate the flow of coolant properly.
  • Coolant leak (water pump, radiator, hose etc.): A coolant leak can occur due to a damaged or corroded component such as the water pump, radiator, or hoses, leading to loss of coolant and potential engine overheating.
  • Radiator Fan: A faulty radiator fan can lead to engine overheating due to insufficient airflow over the radiator when the vehicle is stationary or moving slowly.
