[1-Year Manufacturer Replacement : Fast, Direct] Backed by both the manufacturer and seller, you get double assurance—any issue is resolved quickly and efficiently Reliable Cooling Solution for 3.7L & 4.7L Jeep, Dodge, and Chrysler Engines Is your SUV or truck showing signs of a failing water pump—overheating, coolant loss, or leaks near the front of the engine? The BDELI AW7163 water pump is a direct-fit, upgraded replacement designed to restore and enhance the cooling system performance of your vehicle. We combine superior materials, rigorous testing, and clear instructions for a repair that’s built to last. Engineered as an Upgrade, Built to Last Durable Aluminum Impeller: Many OEM pumps use composite plastic impellers that can degrade over time. The AW7163 features a one-piece cast aluminum impeller that withstands heat, coolant chemicals, and high-RPM operation far better, maintaining optimal coolant circulation for the long haul. Superior Gasket for a Leak-Free Seal: To address the most common post-installation issue, we include a robust rubber composite gasket. This material offers better compression recovery and sealing properties than basic paper gaskets, providing a reliable seal when installed correctly on a clean surface. Certified Manufacturing & Final Validation: Every pump is produced under the strict protocols of ISO 9001 & IATF 16949 certified quality management systems. Prior to shipment, each unit undergoes a final validation check using professional-grade equipment to confirm proper flow, pressure, and—most importantly—a perfect seal. Technical Specifications & Contents Impeller: High-strength aluminum alloy. Housing: Cast aluminum. Seal & Bearing: High-performance mechanical seal and long-life bearing assembly. What’s in the Box: 1 x BDELI AW7163 Water Pump Assembly 1 x Premium Rubber Composite Mounting Gasket (Mounting bolts may be pre-installed on the pump, depending on application) Step-by-Step Installation Guide & Critical Leak-Prevention Tips Project Difficulty: Easy to Moderate (★★☆☆☆) This is one of the more accessible water pump replacements. If you can change an alternator or starter, you have the skills needed. Estimated Time: 60 - 90 Minutes (Includes coolant drain and refill time) Tools & Supplies You Will Need: Basic metric socket set and wrenches Screwdrivers, pliers Drain pan New coolant (Consult your owner's manual for type, typically HOAT) Gasket scraper or abrasive pad for surface cleaning Key Installation Steps: Safety First: Ensure the engine is completely cold. Disconnect the negative battery terminal. Drain Coolant: Place a drain pan underneath. Open the radiator or block drain petcock, or disconnect the lower radiator hose. Remove the Old Pump: Relieve tension on the serpentine belt and remove it. Disconnect any hoses from the pump. Unbolt and remove the old water pump. THE MOST CRITICAL STEP – Surface Preparation: Thoroughly clean the engine block mating surface. Use a gasket scraper to remove all traces of the old gasket material until the surface is perfectly smooth, flat, and clean. Any debris will cause a leak. Install the New Pump: Place the new rubber composite gasket onto the clean surface (do not apply sealant). Position the BDELI AW7163 pump, hand-start all bolts, and then tighten them in a criss-cross pattern to the specified torque. Reassemble: Reconnect hoses and install the serpentine belt. Refill & Bleed: Refill the cooling system with fresh coolant via the overflow tank. Start the engine, turn the heater to full hot, and let it run until the thermostat opens. Top off the coolant as needed after the system cools, and check meticulously for any leaks around the new pump. Frequently Asked Questions (FAQ) Q: What’s the real advantage of an aluminum impeller? A: Long-term material integrity. Aluminum resists the corrosion, erosion (cavitation), and heat distortion that can slowly degrade plastic impellers, helping to maintain the pump's designed efficiency over its entire service life. Q: I followed the steps but my pump is leaking.
