URO BMW Cooling System Parts & Accessories

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

If your vehicle is struggling with cooling problems, the culprit could be the thermostat. Look out for signs like prolonged warm-up periods at highway speeds (indicative of a stuck-open thermostat) or consistent overheating (a sign of a stuck-closed thermostat). These issues can lead to performance issues and potential damage to crucial vehicle parts.

Key Features:

Ensured compatibility with your vehicle High-flow OE-style design ensures optimal engine cooling Factory housing dimensions for easy installation and secure hose connections Includes a temperature sensor where needed Constructed from durable alloy or composite material to resist warping or cracking, preventing coolant leaks

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. If your vehicle is not getting up to temperature when driving, the thermostat is more than likely stuck open. Your engine does not get up to the proper operating temperature where it runs the most efficiently. To fix this problem and get your vehicle's heat restored, replace your thermostat.

The coolant expansion tank in your vehicle provides a reservoir for excess fluid as it expands and contracts due to temperature changes. However, frequent exposure to these extreme fluctuations can cause the tank to crack or break over time. To maintain proper coolant levels within the cooling system, any damage to the tank—such as cracks, broken fittings, or damaged mounting points—requires immediate replacement.

Turbocharger oil feed lines are often overlooked, but they play a critical role in turbo longevity. Replacing a worn or original feed line is an inexpensive safeguard against premature turbo failure. The oil feed line delivers a constant supply of clean, pressurized oil to the turbocharger bearings. Over time, exposure to extreme exhaust heat and repeated thermal cycling can cause oil to break down inside the line, leading to carbon buildup and restricted flow. Reduced oil supply quickly results in elevated bearing temperatures and accelerated wear. Installing a new turbo oil feed line restores proper oil delivery, helping maintain stable bearing temperatures and reliable lubrication. Many updated or upgraded feed lines feature improved materials, refined routing, or additional heat shielding to better withstand the high-temperature environment surrounding the turbocharger. Benefits of replacement: Helps prevent oil starvation caused by internal restriction Protects turbocharger bearings from heat-related wear Extends overall turbocharger service life Recommended preventative maintenance during turbo replacement or high-mileage service Especially important for increased boost or upgraded turbo applications In short, replacing the turbo oil feed line is a smart preventative maintenance step that supports long-term reliability and consistent performance.
