BMW 850CI expansion tank typically cost between $46.99 and $126.99.

The BMW 850CI expansion tank is a component of the vehicle's cooling system. It is responsible for storing and regulating the coolant fluid as it expands and contracts with temperature changes. The expansion tank is typically located near the radiator, usually on the passenger side of the engine compartment.

The typical lifespan of a BMW 850CI expansion tank can vary depending on various factors such as driving habits, maintenance, and environmental conditions. However, on average, the expansion tank in a BMW 850CI can last anywhere from 80,000 to 120,000 miles. It is recommended to regularly inspect the expansion tank for any signs of leakage or cracks and replace it if necessary to ensure proper cooling system function.

Signs of a Faulty BMW 850CI Expansion Tank

  1. Coolant Leaks: If you notice coolant pooling underneath your BMW 850Ci, it could indicate a faulty expansion tank. Check for any visible leaks or dripping coolant from the tank.
  2. Overheating Engine: A malfunctioning expansion tank can lead to poor coolant circulation, causing the engine to overheat. Keep an eye on your temperature gauge, and if it consistently reaches high levels, it might be due to a faulty expansion tank.
  3. Low Coolant Level: A failing expansion tank can result in the loss of coolant. If you frequently find that your coolant level is low, it could be a sign of a leak or crack in the expansion tank.
  4. Hissing or Whistling Noises: Faulty expansion tanks may cause air to be sucked into the cooling system, resulting in hissing or whistling sounds. These noises often occur when the engine is running or immediately after shutting it off.
  5. Visible Damage: Inspect the expansion tank for any cracks, bulges, or other signs of physical damage. Over time, the plastic housing of the tank can deteriorate, leading to leaks and other issues.
  6. Coolant Odor: If you detect a sweet or pungent smell of coolant coming from your engine bay, it could signal a leaking expansion tank. Be cautious as inhaling coolant vapor can be harmful, so address the issue promptly.
  7. Engine Misfire or Poor Performance: In some cases, a failing expansion tank can cause engine misfires or erratic performance. This occurs when coolant enters the combustion chamber, affecting fuel mixture and ignition.

If you suspect a faulty expansion tank in your BMW 850Ci, it's crucial to have it inspected and repaired by a qualified mechanic to avoid further damage to your vehicle's cooling system.
