Airtex AW3401 Engine Water Pump Assembly For Automotive Use

Airtex AW3401 Engine Water Pump Assembly for Automotive Use is a direct‑fit coolant pump designed to circulate engine coolant and maintain proper operating temperatures. It is described as interchangeable with Airtex AW3401 and is cataloged under WP‑538, with cross‑interchanges including Chrysler EA259, Jeep J3227694, Jeep J3234427, and Jr775050, supporting a range of Jeep and Chrysler applications. This pump is intended to replace the factory water pump in vehicles that use the AW3401/WP‑538 family geometry and mounting interfaces, aligning with belt‑driven cooling systems. When installed, it helps push coolant from the radiator through the engine block and back to the radiator, contributing to effective thermal management during both normal driving and higher‑load conditions. Buyers should verify exact fitment by comparing the cross‑reference list to their vehicle’s make, model, and year, and consult the vehicle’s service manual to confirm gasket interfaces, mounting points, and belt routing before purchase and installation.
