Detailed Description

Metelli PA661 is an OE-style engine water pump for Mercedes-Benz C280, C36 AMG, SL320, and E320 applications listed below. The pump is built with an aluminium housing and a cast iron impeller to support coolant flow through the engine, while the roller/ball bearing construction helps maintain stable shaft support during operation. This part cross-references Gates 21864 and Beck/Arnley 131-2224 for the same application. Use PA661 when replacing a worn or leaking Mercedes-Benz water pump on 1994 E320, 1996-1997 C280, 1996-1997 C36 AMG, or 1997 SL320 models with the listed engine design note.

What This Water Pump Helps Address

  • Coolant leakage from a worn pump seal or gasket
  • Overheating caused by reduced coolant circulation
  • Noise from a failing pump bearing
  • Impeller wear that limits coolant movement
  • Cooling system service on Mercedes-Benz E320, C280, C36 AMG, and SL320

Installation Notes and Tips

Confirm engine code and fitment details before installation, especially for the 1997 Mercedes-Benz SL320 with engine design 104.991 water pump fitment. Inspect the mounting surface, replace the O-ring and seal surfaces as needed, and refill the cooling system with the correct coolant mixture after installation. Verify belt condition and pulley alignment during water pump replacement.

Quality Assurance

Metelli PA661 is a new replacement part built with aluminium housing, a cast iron impeller, and included sealing components for a complete cooling-system service replacement.
