Detailed Description
Metelli PA379 is an OE-style replacement water pump for BMW cooling systems that require a cast iron impeller and aluminium pump housing. The 78 mm impeller diameter and 14-vane design support coolant circulation through the engine, while the roller/ball bearing assembly is built for rotating support in normal service conditions. This part cross-references Gates 1360 for the same application. If you are replacing a worn BMW 530i water pump, a BMW 528i water pump, or a BMW 735i water pump, PA379 provides a direct service part reference for those listed vehicles.
What It Helps Address
- Coolant circulation loss from a worn or damaged pump
- Leakage at the pump mounting surface
- Noise from bearing wear in the water pump assembly
- Overheating caused by reduced coolant flow
- Cooling system service on listed BMW applications
Installation Notes and Tips
Verify engine application before installation, especially on the 1979 BMW 528i, which is listed without disengaging the fan. Replace the included gasket during installation and inspect the mating surfaces for corrosion, old seal material, or debris. Confirm pulley alignment, belt condition, and coolant condition before returning the vehicle to service.
Quality Assurance
Metelli supplies new replacement cooling components built to match the listed application requirements. PA379 is a new part and includes the gasket needed for installation on the specified vehicles.
