Genuine BMW – 13411721907 – Lower Radiator Breather Hose (13-41-1-721-907)

Over the years and with exposure to extremely hot coolant, the coolant hoses in your vehicle can take a beating. Being made of reinforced rubber, these hoses can fail in a number of ways. Splitting at a hose clamp, swelling, cracking, and breaking are just a few of the ways this hose can leave you stranded. Replace it at the first sign of wear to keep your coolant in your engine.

With the proper diameter, bends, and lengths, this is the perfect replacement for any swelled or damaged hose. An easy installation, it’s piece of mind the next time you are on a long trip or your morning commute.

During your radiator hose change, fluid loss is inevitable. Be sure to browse the website to get the proper replacement for your vehicle sent directly to your door. Also, be sure to order a new thermostat housing, as the stock plastic units often get broken or warped during removal.

Hose runs from the U shaped hose to the S hose running to the throttle body.
