JDMSPEED Water Pump for Chevrolet GMC Vortec 4.8L 5.3L 6.0L with Gasket Kit — OE Fit, High-Flow Impeller

JDMSPEED replacement water pump with gasket is a direct-fit cooling pump kit for Chevrolet and GMC 4.8L, 5.3L, and 6.0L Vortec engines that includes all seals for a complete swap.

This replacement water pump is built to match OE fitment for a wide range of GM trucks and SUVs — including Tahoe, Yukon, Avalanche, Escalade and select Hummer/Isuzu/Saab installations — and comes with the gaskets and seals needed for installation. It combines an upgraded impeller profile, hardened bearings, and an anti-corrosion finish to promote consistent coolant flow and extended service life. Every unit undergoes leak and hub-pull testing to confirm durability before it ships.

Will this water pump fit my vehicle?

If your vehicle uses a GM Vortec 4.8L, 5.3L, or 6.0L engine from the compatible years, this JDMSPEED pump is designed as a direct replacement for the listed OEM numbers. Check the part numbers and engine code in your service manual to confirm compatibility. The pump replaces a broad set of OE and aftermarket numbers to simplify selection.

• Direct replacement for OE numbers like 130-7340, 130-7341, 130-7320, AW5087 and AW5104
• Also fits many cross-reference numbers including WP-9409, T7052, 45005, 19195104, 12456113
• Commonly used on Chevrolet Avalanche, Tahoe; GMC Yukon, Savana; Cadillac Escalade and similar GM Vortec applications

How does this pump improve cooling system performance?

The pump features an upgraded impeller geometry and smooth internal flow passages to help maintain steady coolant circulation across the engine. Hardened bearings and an improved shaft design reduce wear and vibration, supporting stable operation under load. Anti-rust coatings and unitized seals protect components from corrosion and extend usable life.

• High-flow impeller for consistent coolant movement
• Hardened bearings and reinforced shaft for long service life
• Anti-corrosion finish and permanently-sealed bearings for low maintenance

What is included and what testing does the pump undergo?

The kit ships complete with the water pump and all necessary gaskets and seals, so you can replace the unit without sourcing extra parts. Each pump is leak-tested and hub-pull tested to validate assembly integrity before it reaches you. Installation requires basic mechanical tools and common workshop procedures for water pump replacement.

• One water pump plus full gasket/seal set included
• 100% leak testing and hub-pull testing performed for reliability
• Two ports and OE-style mounting for straightforward fitment

How do I know when to replace the water pump?

Look for signs like coolant leaks at the pump, unusual bearing noise, engine overheating, or rough idling temperatures that indicate reduced coolant flow. During scheduled cooling-system service or if the vehicle has high mileage, replacing the pump and gasket as a preventive measure can avoid roadside failures. Always inspect belt-driven components and hoses while replacing the pump for a comprehensive repair.

• Visible coolant leakage around the pump housing
• Grinding or rumbling noises from the pump pulley area
• Recurring engine overheating or erratic temperature readings

Who is this for: This JDMSPEED water pump kit is aimed at DIY mechanics and professional technicians servicing GM trucks and SUVs with 4.8L, 5.3L, or 6.0L Vortec engines who need a direct-fit replacement with included gaskets and validated testing. It suits owners replacing a failed OE pump, performing a cooling-system overhaul, or upgrading to a more durable aftermarket option for everyday driving and tow/haul duties.
