Detailed Description

Built for the Porsche 911 cooling system, the Metelli PA1162 combines a 64.7 mm brass impeller with a 30 mm roller/ball bearing assembly for smooth rotation and consistent coolant circulation. The 22.2 mm pulley width and 6-groove pulley configuration support proper belt engagement, while the aluminium housing helps provide a durable mounting surface. This part cross-references Porsche OE numbers 99610601172 and 99610601174 for the same application.

Common Cooling System Issues

• Coolant leakage from a worn pump seal or gasket
• Noise from a failing water pump bearing
• Reduced coolant flow from impeller wear or damage
• Overheating caused by poor coolant circulation
• Belt drive concerns related to pulley wear or misalignment

Installation Notes and Tips

Verify the pulley groove count, pulley width, and OE cross-reference before installation on your Porsche 911. Replace the gasket during service, inspect the belt drive components, and confirm the cooling system is properly filled and bled after installation. The Metelli PA1162 is a direct replacement part for the listed fitment and should be matched to the vehicle’s original configuration.

Quality Assurance

Metelli supplies new aftermarket cooling components built to match the listed application details for the Porsche 911. Confirm fitment by year and OE reference before ordering.
