Product Details

Gates Water Pump (Standard) line focuses on OE-quality fit and consistent operation for cooling-system service. The Gates 43004 is manufactured with premium alloy materials and undergoes functional testing of seals and bearings, plus leakage testing of the casting and assembled pump. For Jeep CJ5 owners servicing a 1959-1971 cooling system, this water pump provides the correct standard rotation and accessory-belt drive layout for the listed application. This part cross-references Airtex Water Pumps AW52 and GMB 110-2052 for the same application.

What It Helps Address

• Coolant circulation issues caused by a worn or leaking pump
• Overheating related to reduced water flow
• Noise from worn pump bearings or seals
• Cooling-system service on a Jeep CJ5 with accessory-belt drive
• Replacement needs for a standard-rotation engine water pump

Installation Notes

Fits 1959-1971 Jeep CJ5, N/A. Confirm pulley alignment, outlet orientation, and accessory-belt routing before installation. Replace the gasket during service and verify that the cooling system is clean, filled correctly, and free of leaks after installation. Match the pump to the vehicle’s standard-rotation, accessory-belt configuration and the listed two-outlet layout.
