AW6348 Water Pump for 3.5L/3.7L Engines - Reliable Replacement

In this review the AW6348 Water Pump is evaluated as a direct replacement option for owners of 2011-2019 Ford and Lincoln models and select Mazda vehicles. The bottom line: this pump is best for DIY mechanics and independent shops who need a cost-effective, factory-tested replacement that includes all gaskets for a straightforward install. The most compelling reason to buy is its focus on durability and leak-free performance thanks to a unitized seal and top grade bearing, paired with TS16949 manufacturing and 100% function and leakage testing.

Key Features

• Complete fitment: Supplied with all necessary gaskets and seals to simplify installation and reduce trips to the parts store.
• Durable sealing: A unitized seal design reduces the chance of coolant leaks over time, improving long-term reliability.
• High-quality bearing: Top grade bearing inside is intended to deliver smoother operation and longer service life than lower-cost alternatives.
• Corrosion resistance: Vibration polishing of the housing gives a shinier, more corrosion-resistant surface for improved longevity.
• Factory testing: Manufactured in TS16949 certified facilities and 100% function and leakage tested to reduce the likelihood of early failures.
• Warranty protection: Comes with a 1 year or 50,000 km warranty for added confidence after purchase.

Who It's For

This pump is aimed at vehicle owners and independent repair shops replacing a failed or aging water pump on compatible 3.5L and 3.7L engines, including many 2011-2019 Ford Edge, Fusion, Flex, Explorer, Taurus and Lincoln MKS MKZ MKT MKX models, as well as Mazda 6 and CX-9. It suits buyers who want a balance of cost savings and proven manufacturing oversight rather than an OEM-priced part.

Those who need factory dealer parts for warranty transfer or who prefer a branded OEM item for resale vehicles may want to look elsewhere. Also, installers who expect a premium finished aesthetic beyond functional corrosion resistance might prefer higher-end aftermarket options.
