The water pump is a known weak point across all BMW models, requiring servicing every 60,000 miles. Along with the water pump, it’s wise to replace the thermostat to ensure your cooling system operates at peak efficiency.

A failing water pump can show early warning signs like coolant leaks or a whining noise from the engine bay—but with electric water pumps, failure can be sudden, often with no warning beyond rapid overheating.
If you suspect your water pump is on its way out, prompt replacement is critical to avoid engine damage. Stay alert to any changes in cooling system performance.
Note: Aluminum mounting bolts are single-use and must be replaced during installation.

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.
Enhance your BMW's cooling system with Graf's premium water pump—available now at Turner Motorsport!
