Pump Assembly

The water pump is a known failure point on most BMWs, new and old. Older model BMWs come from the factory with a mechanical fan that features a plastic impeller. If your BMW still has a water pump with a plastic impeller, you should upgrade to one with a metal impeller to avoid future failure. New BMWs utilize an electric water pump that cost BMW millions of dollars to design - when it is working it is great, unfortunately these fail so regularly that we recommend replacing your electric water pump every 60,000 miles to avoid stranding yourself on the side of the road. We have hand selected the best OE suppliers for replacement water pumps so you don't have to pay the high cost of Genuine BMW. However, if you're someone who only puts Genuine BMW parts on your car, we understand - that's why we have those available for you as well.

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.

Factory water pumps often feature plastic impellers, which are prone to damage and deterioration due to constant heat exposure. Over time, the plastic becomes brittle and can send debris into your engine's coolant passages, leading to potential engine damage. 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. Perfect Fit for BMW: Precision-engineered to match your BMW's exact specifications, guaranteeing a straightforward installation and perfect fit. Upgrade to the Graf High-Performance Water Pump and protect your BMW's engine from costly damage. Ensure optimal cooling performance and drive with confidence, knowing your cooling system is built to last.
