BMW Cooling System Parts & Accessories for BMW G32 640i xDrive B58 3.0L

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.

Situated on the engine's oil filter housing, this set of gaskets plays a crucial role in sealing the housing to the engine block. Over time, exposure to heat and oil can cause these rubber gaskets to become brittle, compromising their ability to seal the mating surfaces effectively.

Given that oil flows from the block to the filter housing, any leaks from these seals can lead to significant issues. Fortunately, BMW offers a comprehensive set of these gaskets, providing a solution to all oil leaks and restoring your vehicle to optimal performance.

How can you identify if your oil cooler gaskets are leaking?

Oil drips beneath the car when it's parked. Visible oil accumulation on the intake/heat exchanger side of the engine block. Frequent low oil level warnings during driving.

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.
