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.

If your water pump is on its way out, you might spot coolant leaks or hear a faint whining sound from under the hood. Don’t wait—if you suspect it’s failing, replace it before it leaves you stranded. The tricky part with electric water pumps is that they can fail silently—no noise, no leaks—just sudden overheating. Stay alert for early warning signs that it’s time to swap out your water pump and keep your cooling system running strong.

Your vehicle’s oil cooler does exactly what its name implies—it cools engine oil by circulating it through a series of fins filled with flowing coolant. This process helps regulate oil temperature before and after it passes through the oil filter. If the oil cooler fails, it 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.
