A-Premium Engine Water Pump for Jeep 6-Cyl 4.0L — Aluminium Housing, OE Fit with Gasket

A-Premium's aluminum engine water pump for the 6-cylinder 4.0L Jeep delivers direct-fit cooling circulation with a durable steel impeller and six mounting holes for secure installation.

If you're restoring cooling performance on a 1999–2004 Jeep Grand Cherokee or a 2000–2006 Jeep Wrangler with the 4.0L inline-six (VIN S), this A-Premium replacement water pump is engineered to match OE fitment while using a lightweight aluminum housing for corrosion resistance. The kit includes the pump and a dedicated gasket so you have the core parts needed for a standard replacement, and the pump is driven by the vehicle's serpentine belt like the factory unit.

How does this pump match original equipment fit for my Jeep?

The A-Premium unit is designed to replicate the factory mounting points and hub fit, ensuring bolt pattern, hub hole count, and belt drive align with the original part. That reduces adjustments during installation and maintains system alignment for the serpentine belt and associated pulleys.

• Exact six mounting-hole pattern for OE-style bolt placement
• Hub hole quantity matched to original for direct connection to engine
• Serpentine-belt drive configuration to fit the existing accessory drive
• Reference numbers supplied to cross-check compatibility (e.g., AW7164, 05012366AF)

What are the pump’s construction and performance features?

The pump uses an aluminum housing for lighter weight and improved resistance to rust compared with cast-iron alternatives. Inside, a five-vane steel impeller operates with reverse rotation to move coolant through the engine’s passages effectively while matching OEM flow direction.

• Housing material: corrosion-resistant aluminum for longevity
• Impeller: five steel vanes for robust coolant movement
• Impeller rotation: reverse rotation to match engine flow requirements
• Durable manufacturing aimed at consistent circulation and fit

What comes in the kit and how does that affect installation?

The package contains the water pump and a replacement gasket to seal the mating surface, simplifying most routine replacements. Because the major sealing part is included and the mounting points match OEM, most professional or experienced DIY installers can complete the job without sourcing additional core hardware.

• 1 x aluminum engine water pump manufactured to fit 4.0L L6 Jeep engines
• 1 x engine water pump gasket included to ensure proper sealing
• Five impeller vanes and six mounting holes already integrated
• Reference numbers included to confirm cross-compatibility
