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.

The Graf High-Performance Water Pump is engineered to enhance your BMW's cooling system, ensuring peak performance and longevity. This essential component efficiently pumps coolant throughout the engine block, maintaining optimal operating temperatures.

Graf has addressed this issue by designing a water pump with a robust stainless steel impeller, providing unmatched durability and reliability.

Key Features:

Stainless Steel Impeller: The upgraded impeller design offers superior strength and longevity compared to the factory plastic version, preventing failure and enhancing the water pump's lifespan. Improved Cooling Efficiency: Enhanced coolant circulation helps maintain ideal engine temperatures, reducing the risk of overheating and ensuring consistent performance. High-Performance Durability: Built to withstand the rigors of high-performance driving, this water pump ensures reliable cooling under demanding conditions.

Don't take your car's cooling system for granted! One of the biggest weak points is the cooling system. Replacing your water pump will go a long way for keeping your car on the road and operating properly. If you have noticed a slight coolant leak or see a small amount leaking from the bottom of the pump, its time to replace it. Don't get stuck on the side of the road waiting for a tow truck, replace your water pump as soon as it fails.

Graf manufactures a wide range of cooling system repair parts for many European vehicle makes including BMW and Mini. With a sharp focus on quality materials and precision manufacturing, this company brings you high quality replacement parts that are meant for the long haul.
