Detailed Description

The Airtex AW6344 is an engine water pump engineered for cooling system replacement where correct fit and dependable circulation matter.

The design is application specific, helping maintain proper alignment and operation in the intended vehicle platform.

What It Helps Fix

• Coolant leakage from a worn pump seal or housing
• Overheating caused by reduced coolant circulation
• Noise from failing bearings or hub wear
• Impeller wear that lowers cooling efficiency
• Fitment issues from incorrect replacement pump design

Installation Notes and Tips

Confirm serpentine belt routing, standard rotation, and pulley alignment before installation. Inspect the cooling system, belt condition, thermostat, and hoses at the same time to avoid repeat repairs. Flush contaminated coolant and verify the system is filled and bled according to the vehicle service procedure after installation.
