BMW 850i expansion tank typically cost between $5.39 and $126.99.
The BMW 850i expansion tank is a component of the vehicle's cooling system. It is responsible for storing excess coolant when the engine temperature rises, allowing for expansion and contraction. The expansion tank is typically located near the radiator at the front of the engine bay. It can be identified by its translucent plastic construction and the presence of coolant hoses connected to it.
The typical lifespan of a BMW 850i expansion tank can vary depending on several factors such as usage, maintenance, and driving conditions. However, under normal circumstances, the expansion tank can last anywhere from 80,000 to 120,000 miles before needing replacement. It's important to keep an eye on any signs of leakage, cracks, or coolant issues and promptly address them to ensure optimal functioning and longevity of the expansion tank.
Signs of a Faulty BMW 850i Expansion Tank
Sure! Here are some common signs that indicate a faulty expansion tank in a BMW 850i:
- Coolant Leaks: One of the most common signs is coolant leakage from the expansion tank. If you notice puddles or stains of coolant under your vehicle, it could be due to a cracked or damaged expansion tank.
- Overheating Engine: A faulty expansion tank can lead to coolant loss, which in turn can cause the engine to overheat. If you frequently experience your engine running hotter than usual or overheating, it might be related to the expansion tank issue.
- Low Coolant Level: If you notice that the coolant level in your BMW 850i is consistently dropping, it may be a sign of a faulty expansion tank. This can occur due to leaks in the tank itself.
- Swollen or Deformed Tank: Inspect the expansion tank visually. If you notice any irregularities such as swelling, deformations, or cracks on the tank, it is likely that the expansion tank needs to be replaced.
- Steam or Smoke: If you observe steam or smoke coming from under the hood, it can be an indication of a coolant leak caused by a faulty expansion tank.
- Dashboard Warning Light: Some BMW models have a low coolant level warning light on the dashboard. If this warning light illuminates or stays on, it could be a result of a problematic expansion tank.
- Spongy Brake Pedal: In certain cases, a faulty expansion tank can allow coolant to enter the brake booster vacuum hose, leading to a spongy brake pedal feel. If your brake pedal feels soft or less responsive than usual, it could be related to the expansion tank issue.
It is important to address these signs promptly and have the expansion tank inspected and repaired or replaced by a qualified mechanic or BMW dealership to prevent further damage to the cooling system.
