Detailed Product Overview

The Metelli PA369 water pump is engineered for BMW 325i, 325is, 325iX, 525i, and 528e fitments where dependable coolant circulation is required. Its aluminium housing supports durability in the engine bay, while the cast iron impeller and roller/ball bearing construction are selected for consistent pump operation. The PA369 is a direct replacement-style water pump for vehicles that need a serviceable cooling system component, and it cross-references Airtex AW9120 for the same application.

What This Water Pump Helps Address

• Coolant circulation problems caused by a worn pump
• Overheating from reduced water pump performance
• Coolant leaks at the pump mounting surface
• Noise from bearing wear in the cooling system
• Impeller wear that can reduce coolant flow

Installation Notes and Tips

Confirm engine fitment before installation and compare the original pump to the Metelli PA369 for housing, impeller, and mounting alignment. Replace the gasket during installation and inspect the surrounding cooling system components, including hoses, thermostat, and drive belt condition, to help complete the repair correctly. Proper coolant fill and bleeding are important after installation to restore normal system operation.

Quality Assurance

Metelli supplies this water pump as a new replacement component with gasket included. The PA369 is built with an aluminium housing, cast iron impeller, and roller/ball bearing construction to meet the demands of routine cooling system service.
