Detailed Description

The Hepu P415 is designed for BMW vehicles that use a mechanical engine water pump with a pulley and sensor bore. It is compatible with select BMW 650i, 650i xDrive, 650i Gran Coupe, 650i xDrive Gran Coupe, 550i, 550i xDrive, 550i GT, 550i GT xDrive, 750i, 750i xDrive, 750Li, 750Li xDrive, X5, and X6 models. The pump is built to OE standards and undergoes pressure and leakage testing to help verify sealing performance before installation.

This part number, P415, is intended for BMW cooling system repairs where the original pump configuration uses a plastic impeller and a pulley-driven mechanical design. The included seal and accessories support a cleaner service job, while the sensor bore allows use on applications that require that housing feature without supplying the sensor itself.

Common Problems This Part Can Address

• Coolant leakage from a worn water pump housing or seal
• Overheating caused by reduced coolant circulation
• Noisy or failing pump bearings
• Impeller wear that reduces cooling efficiency
• Service replacement for a BMW mechanical water pump with pulley

Installation Notes and Tips

• Verify the vehicle uses a mechanical pump with pulley and sensor bore before ordering.
• Confirm the application does not require a sensor, since the sensor is excluded.
• Inspect the cooling system, hoses, thermostat, and related components during replacement.
• Use the included seal during installation and follow BMW service procedures for torque and coolant bleeding.
• Check fitment carefully on BMW 650i, 750i, X5, and X6 models, since cooling system configurations can vary by engine setup.

Quality Assurance

Hepu states that its water pumps are built with precise German engineering and are tested for pressure and leakage to support OE-level performance. The P415 is an OEM-standard new replacement part for BMW cooling system service.
