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.

Upgrade your cooling system setup with our Heavy Duty Radiator Mounting Brackets, engineered to deliver maximum structural support and a refined engine-bay aesthetic. After decades of heat cycles and hard driving, your E30's factory plastic mounts inevitably become brittle, faded, and prone to cracking, risking damage to your radiator. Our radiator mount upgrade completely replaces those tired OEM units with a high-strength alternative built to handle the rigors of spirited driving, track days, and engine swaps. Whether you are performing a full cooling system refresh or executing an M5X swap that utilizes an E36-style radiator, these brackets provide the ideal balance of precision fitment and rugged dependability.

Crafted with a premium brushed stainless steel finish, this kit does more than secure your radiator; it radically improves the visual appeal under the hood by swapping out cheap, weathered plastic for durable steel hardware. Designed as a true direct bolt-on solution, the brackets align seamlessly with factory mounting locations, eliminating the need for frustrating custom fabrication, cutting, or drilling. They clamp down firmly to eliminate unwanted radiator movement, ensuring your cooling stack remains locked in place under heavy vibration.

Keeping your E53 X5 automatic transmission cool is essential for longevity and peak performance. The factory transmission thermostat circuit relies on plastic housings and o-ring seals that deteriorate over time. When the transmission thermostat fails or it's mounting assembly cracks, coolant loss follows putting your transmission at risk of overheating under load.
