Product Details

The Febi 46221 is a high-quality replacement expansion tank cap (also known as a radiator cap or coolant reservoir cap) designed for various BMW models. This essential cooling system component maintains proper pressure in the cooling system, ensuring optimal engine temperature regulation and preventing coolant loss.

Key Features:

  • Precision-engineered plastic construction with yellow and black finish
  • Maintains proper cooling system pressure for efficient operation
  • Direct OEM replacement - compatible with BMW part number 17117521071
  • Manufactured by Febi, a trusted name in European automotive components
  • Designed to meet or exceed original equipment specifications

This expansion tank cap is a critical maintenance component that should be replaced periodically or when signs of wear appear, such as cracking, loss of seal integrity, or pressure release issues. A properly functioning cap prevents coolant evaporation, maintains system pressure, and protects your engine from overheating damage.

Great interface for figuring out if product fits my vehicle.

best price found, easy order process. Free shipping a BIG plus!

Your prices seem very reasonable. I hope the serpentine belt fits my 2003 GMC truck.

So far so good. If the parts fit, even better.

the item which I thought I ordered was not correct.the actual shipping took forever. Upon getting the part and realizing it wasn't what I ordered, I tried to contact customer service but a slow response by email. I have send emailed back asking how to return this product with no answer. I feel like the item I ordered was not accurately portrayed. so, I will overpaid for a stupid light kit not at all what I wanted :-(

Autoplicity has the best prices and I have checked a lot of places for my Milodon Swinging oil pickup. They had it in stock and shipped it out the next day. Thanks for the great pricing, service and communications. You are in my saved sellers.
