BMW Cooling System Parts & Accessories for BMW 4 Series F32 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

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.

**** DOES NOT INCLUDE HARDWARE ****** Hardware - ES4772301 The N55 engine is no stranger to oil cooling problems, that�s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned. The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat Features Include: 20�C/68F Lower Than Stock Rock Solid Housing - CNC machined housing. Real Thermostat - Equipped with a real thermostat, not an always open solution. For use in hot and cold climates Quick Installation - Takes only 30 minutes to install.

**Cooler only—housing not included.** Your vehicle’s oil cooler functions exactly as its name suggests—it cools engine oil by circulating it through a series of fins filled with coolant, regulating its temperature before and after passing through the oil filter. A failing oil cooler can cause coolant and engine oil to mix, similar to a blown head gasket. Replace your leaking or damaged oil cooler today to prevent further issues. **Seal not included.**

Engine oil coolers are critical for keeping oil temperatures in check, preventing premature breakdown and maintaining proper lubrication. When oil gets too hot, it loses viscosity and can't effectively protect vital engine components like bearings—which can lead to serious, even catastrophic, failures. If your oil cooler is damaged or has failed, replacing it is essential to protect your engine and keep everything running smoothly.

Engine oil coolers help reduce the oil temperature, preventing the oil from breaking down prematurely and losing its lubricating properties. Engine oil coolers play a crucial role in regulating oil temperature, ensuring proper lubrication, and optimizing engine performance and longevity. Engine oil that is too hot drops in viscosity and does not provide adequate lubrication to sensitive engine components such as bearings, which can fail catastrophically if not properly lubricated. If your engine oil cooler has been damaged or has failed we recommend replacing it to ensure no damage occurs to your engine.

The N55 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned.
