Detailed Description

Aisin WPZ-801 is an OE-manufactured style engine water pump for the 2011-2014 Mazda 2. Built from aluminum die-cast construction with a cast aluminum housing and stamped steel impeller, it is engineered for the cooling system service needs of timing belt-driven engines.

This part cross-references Gates 21143 for the same application.

Common Repair Uses

• Overheating caused by reduced coolant circulation
• Bearing noise or pulley wobble from a worn pump assembly

Installation Notes and Tips

Confirm timing belt alignment before removing the old pump, since this unit is driven by the timing belt. Inspect the belt, tensioner, and related cooling components during installation. Mounting hardware is not included, and installation warnings are noted by the manufacturer, so follow the vehicle service procedure closely.

Quality Assurance

Aisin manufactures OE water pumps for a wide range of applications, and the WPZ-801 reflects that OE-style engineering approach. It is a standard replacement part built for direct service use on compatible Mazda 2 models.
