Key Features

• Cast aluminum housing for strength and corrosion resistance
• Stamped steel impeller with reverse rotation
• Timing belt driven design with pulley included
• Includes water pump and rubber seal ring
• 100 percent functional testing of seals and bearings
• 100 percent leakage testing of the casting and assembled pump

Detailed Product Description

The Gates 44405 water pump is engineered for vehicles that use a timing belt driven cooling system. Its reverse-rotation impeller and three-outlet configuration are matched to the original engine setup, helping maintain proper coolant circulation in the Acura Integra and Honda Civic platforms listed below.
