Detailed Description

Gates part number 44030 is an engine water pump designed for GM light- and medium-duty platforms that require a reverse-rotation, accessory-belt-driven pump. It is listed for applications such as Chevrolet C1500, C2500, C3500, K2500, K3500, Express 3500, and GMC C2500, C3500, K2500, K3500, Savana 3500, and related Suburban and P-series models. This part cross-references Airtex AW5038 and Dayco DP1011 for the same application.

The Gates Water Pump (Standard) line focuses on OE-quality fit and consistent operation. Each pump is built with premium alloy materials and undergoes functional testing of seals and bearings, plus leakage testing of the casting and assembled unit, helping ensure the pump is ready for installation on compatible Chevrolet and GMC cooling systems.

What It Helps Address

• Coolant circulation problems caused by a worn pump
• Overheating from reduced coolant flow
• Leakage at the pump casting or seal area
• Bearing noise or rough pump operation
• Cooling-system service on Chevrolet and GMC truck, van, and Suburban platforms

Installation Notes and Tips

Verify reverse-rotation application, accessory-belt drive layout, and outlet count before installation. Replace the gaskets supplied with the pump and inspect the mating surfaces, hoses, belt condition, and thermostat during service. Confirm fitment for your exact Chevrolet C2500, GMC K3500, or other listed vehicle by year and engine configuration before assembly.

Gates manufactures this water pump with premium alloy materials and performs 100 percent functional testing of seals and bearings, along with 100 percent leakage testing of the casting and assembled pump.
