OAW Water Pump for GM 4.8L/5.3L/6.0L V8 — OE-fit replacement with gasket & 1-Year Warranty

The OAW G7341 is a direct-fit replacement water pump engineered to restore proper coolant circulation for GM 4.8L, 5.3L and 6.0L V8 engines.

This premium aftermarket pump is built to match original equipment dimensions and flow characteristics, and it ships with the required gasket so you can complete the service in one job. It’s designed for a wide range of Chevrolet, GMC, Cadillac and related GM vehicles from late 1990s through mid-2000s, offering OE-style performance and a 1-year warranty for added confidence.

Which vehicles will this OAW G7341 water pump fit?

The G7341 covers numerous GM platforms across 4.8L, 5.3L and 6.0L V8 families. Fitment spans full-size trucks, SUVs, vans and some specialty models—check the exact year and model list before ordering to confirm compatibility with your VIN and engine variant.

• 6.0L V8: select Escalade, Silverado, Suburban, Yukon, Express, H2, SSR and other models (1999–2006 coverage on many applications)
• 5.3L V8: Avalanche, Silverado, Tahoe, Envoy, Suburban, Express and related models (2000–2006 range on most)
• 4.8L V8: Silverado, Tahoe, Yukon, Express and Savana applications (late‑1990s to mid‑2000s)

How does this pump match OEM expectations?

OAW engineered the G7341 to reproduce the original pump’s form, mounting points and hydraulic performance so it installs and operates like the factory unit. The package includes a replacement gasket to ensure a sealed, leak-free connection when installed correctly.

• OE-style housing and shaft length for correct pulley alignment
• Impeller designed to replicate factory flow and pressure characteristics
• Gasket included to maintain proper sealing and prevent coolant loss
• Backed by a 1-year warranty with a 30-day return window

What should I expect during installation and service life?

Installation follows the same steps as the factory pump—drain coolant, remove accessory components and replace the pump with the supplied gasket. Service life depends on maintenance, coolant condition and belt/drive system health; replacing worn belts, hoses and thermostat at the same time helps maximize longevity.

• Typical install: coolant drain, pulley/serpentine removal, pump replacement and refill
• Use manufacturer‑specified coolant and torque values for fasteners
• Inspect belts, hoses and thermostat when replacing the pump
• Monitor for leaks and proper engine temperature after startup

Why choose this OAW replacement instead of a rebuilt or used pump?

Buying a new OAW G7341 avoids unknown wear in used or rebuilt cores and provides parts and finish consistent with modern aftermarket standards. The included gasket and warranty reduce the risk and extra expense of discovering defects after installation.

• New components reduce risk of premature failure versus used units
• Consistent manufacturing tolerances for better fit and alignment
• Warranty and return policy support if defects appear
• Ships ready-to-install with the necessary gasket included

Who this is for: mechanics, fleet managers and DIY enthusiasts who need a reliable, direct-replacement water pump for GM 4.8L, 5.3L or 6.0L V8 applications. If you want OE-style fitment, a complete gasket in the box, and coverage for many Chevrolet, GMC and Cadillac models from the late 1990s through 2006, the OAW G7341 is a practical choice.
