Engine Oil Pump for Nissan Altima

This DJ Rock engine oil pump, part number OP624, is built for 1993-2001 Nissan Altima applications. It circulates pressurized oil through the engine to help maintain lubrication at rotating and sliding contact points.

Key Features

• Rotary oil pump design with standard pressure and standard volume output
• Crankshaft-driven operation for direct engine synchronization
• Aluminum housing for strength and heat resistance
• Gasket or seal included for service-ready installation
• 8 mounting holes for secure fitment
• Premium-grade construction for consistent oil delivery

Product Details

OP624 is an engine oil pump engineered to maintain steady oil flow under changing engine conditions. The rotary design uses internal moving elements to move oil efficiently, while the pressure relief valve helps regulate system pressure during cold starts and higher engine speeds. The aluminum housing resists warping under heat, and the internal components are built for wear resistance and long-term service. This part cross-references Sealed Power 224-43581 for the same application.

Common Problems It Can Help Address

• Low oil pressure warning conditions
• Reduced lubrication at engine bearings and valvetrain components
• Excessive engine noise related to oil starvation
• Oil pressure fluctuation during cold starts or high RPM operation
• Wear caused by inconsistent oil circulation

Installation Notes and Tips

Verify the crankshaft drive engagement, gasket sealing surfaces, and mounting hole alignment before installation. Clean the oil passages and inspect the pickup, pan, and related lubrication components during service. For 1993-2001 Nissan Altima oil pump replacement, confirm the existing pump style and engine configuration against the vehicle’s service information.
