Detailed Description

The DJ Rock OP632 engine oil pump circulates pressurized oil through the engine to lubricate rotating and sliding components, helping maintain proper oil flow under changing engine speeds and temperatures. Its rotary design uses internal pumping elements to move oil efficiently, while the pressure relief system helps regulate oil pressure during cold starts and higher-load operation. The aluminum housing adds durability and helps resist distortion from heat. This part cross-references 028-0405 and 224-43584 for the same application. For drivers searching for a Nissan Maxima oil pump replacement or an Infiniti I30 engine oil pump, OP632 provides a direct-fit solution for these model years.

What It Helps Address

• Low oil pressure warning conditions
• Reduced oil circulation through the engine
• Excessive engine wear from poor lubrication
• Oil pressure fluctuation during cold starts
• Noisy operation related to oiling system problems

Installation Notes and Tips

Confirm engine application before installation and inspect the oil pickup, gasket surfaces, and related lubrication components. Clean all mating surfaces thoroughly and verify proper oil priming after installation. Because this is a crankshaft-driven rotary pump, correct alignment and torque procedures are important for reliable operation. Fits 1995-2001 Nissan Maxima and 1996-2001 Infiniti I30, N/A.

Quality Assurance
