Based on industry averages you can expect to pay between $5.39 and $126.99 for a BMW 840CI expansion tank.
The BMW 840CI expansion tank is a crucial component of the vehicle's cooling system. It is responsible for storing excess coolant as it expands due to the heat generated by the engine. The expansion tank is typically located near the radiator and is easily identifiable by its translucent or opaque plastic construction. It often has a pressure cap and various hoses connected to it, allowing coolant to flow in and out as needed.
The typical lifespan of a BMW 840CI expansion tank can vary depending on various factors such as usage, maintenance, and environmental conditions. However, on average, the expansion tank of a BMW 840CI tends to last anywhere between 80,000 to 100,000 miles or roughly 10-15 years. It is important to regularly inspect and maintain the cooling system to ensure optimal performance and longevity of the expansion tank.
Signs of a Faulty BMW 840CI Expansion Tank
The most common signs of a faulty BMW 840CI expansion tank include:
- Coolant leaks: If you notice coolant pooling underneath your car or a persistent coolant smell, it could indicate a leak from the expansion tank.
- Overheating engine: A faulty expansion tank can lead to overheating as it fails to properly regulate coolant levels and temperature.
- Low coolant level: If you frequently find yourself needing to top-up the coolant in your BMW 840CI, it may be due to a leak or malfunctioning expansion tank.
- Visible cracks or damage: Inspect the expansion tank for any visible cracks or physical damage, as this can indicate a problem.
- Coolant warning light: Your BMW's dashboard might display a coolant warning light if the expansion tank is malfunctioning or the coolant level is low.
- Discolored coolant: A faulty expansion tank can cause the coolant to become contaminated, resulting in a strange color or appearance.
- Overpressurization: A faulty expansion tank may cause excessive pressure build-up in the cooling system, leading to coolant leaks or other issues.
If you suspect a faulty expansion tank, it is recommended to have your BMW 840CI inspected and repaired by a professional mechanic or authorized BMW service center.
