US Motor Works MCK1094 Engine Water Pump with Fan Clutch

Water Pump and Fan Clutch Kit for BMW Cooling Repair

US Motor Works MCK1094 is a matched engine water pump with fan clutch kit for BMW cooling system service. It is built for direct replacement on select BMW 325i, 525i, X3, X5, 330i, 530i, Z3, M3, and related models, helping restore coolant flow and airflow in one repair.

The US Motor Works Water Pump and Fan Clutch kit line is focused on replacing connected cooling components together, so the water pump and fan clutch work as a coordinated set. That approach is important on BMW applications where a worn fan clutch can place extra load on a new pump, and a failing pump can shorten fan clutch life.

Detailed Product Overview

This matched cooling system replacement is intended for BMW vehicles that use a belt-driven water pump and mechanical fan clutch arrangement. By replacing both components together, you reduce the chance of installing a new pump against a worn fan clutch or replacing a fan clutch against a weak pump. The result is a more complete cooling system service for BMW 325i, 330i, 525i, X3, X5, Z3, and other listed applications. Part number MCK1094 is a practical choice when servicing overheating, circulation, or fan-drive concerns on compatible BMW models.

Common Problems This Kit Can Address

• Engine overheating from reduced coolant circulation
• Weak radiator airflow caused by a worn fan clutch
• Coolant temperature instability during idle or low-speed driving
• Noise or drag from a failing mechanical fan clutch
• Repeat cooling repairs when only one connected component is replaced

Installation Notes and Tips

Replace the water pump and fan clutch together during cooling system service to avoid mixing new and worn components. Inspect the radiator, thermostat, hoses, belts, and coolant condition before reassembly. Confirm exact BMW engine application and notes before ordering, including the M54 note listed for some 2004-2005 325Ci applications. This part cross-references BMW cooling system service applications where a matched pump-and-clutch replacement is required.
