BMW 11151247903 Hose

Description

This product is identified as a Hose based on the manufacturer-provided name and supplied MPN. Hoses are used in various vehicle systems to transfer fluids or gases between components, and their exact function, routing, and specifications may vary depending on the application. Please verify compatibility with the intended vehicle system and operating requirements before installation.

Key Features & Benefits

This hose is pretty straightforward. It connects the engine to the radiator, and it’s how coolant—that’s your antifreeze mix—circulates between the two. Coolant absorbs heat from the engine, then flows through the radiator where it’s cooled down by air flowing through the fins, and then it cycles back to the engine. It’s a closed loop, and the hose is a key part of that. There’s usually an upper and a lower hose, sometimes with smaller bypass hoses as well. Think of it as a vital pathway in your car’s cooling system. The engine generates a lot of heat when it runs, and if that heat isn't managed, things can get damaged quickly – warped heads, cracked blocks, all sorts of trouble. The hose’s job is to reliably move the coolant, preventing overheating. It’s under pressure, and exposed to heat and chemicals, so it needs to hold up. It essentially acts like a shield, protecting the more sensitive parts of the engine.

Symptoms, Risks & Replacements

If this hose fails, it's usually a pretty big deal. You’ll notice if it develops a leak—you’ll see coolant dripping, or you might smell it. Sometimes a hose will just get soft and bulge, which is a warning sign. If it bursts completely, coolant will dump out rapidly, and your temperature gauge will climb fast. Driving with an overheating engine can cause major damage, and repairs get very expensive. It’s a relatively inexpensive part to replace, and doing it preventatively can save you a ton of money and headache down the line. We carry a good selection of them at Fixparts Online, so it’s a pretty easy fix if you decide to tackle it yourself or bring it to a shop. Product information is provided for reference only.
