Detailed Description

The US Motor Works Water Pump and Fan Clutch kit is intended for BMW cooling system maintenance where both the pump and clutch should be renewed together. Replacing only one worn component can leave the other stressed, so this matched set supports a complete repair on 1999-2003 BMW 540i, 2000-2003 BMW X5, 1999-2001 BMW 740i, and 1999-2001 BMW 740iL models. The MCK1098 combines high-quality components with precision machining to help maintain stable engine temperatures and long-term engine durability.

What It Helps Address

• Overheating caused by a worn water pump
• Reduced airflow from a failing fan clutch
• Cooling system noise related to worn rotating components
• Temperature instability during stop-and-go driving
• Repeat repairs when only one cooling component is replaced
