Direct OEM Replacement Oil Pump for Precise Pressure Regulation, Consistent Lubrication Flow, and Long-Term Protection in Toyota 4ZZ, 3ZZ & 1ZZ Engines

Overview:

Maintain optimal oil distribution and extend the operating life of your Toyota 4-cylinder engine with our Premium Engine Oil Pump Assembly, direct factory replacement for Part Numbers 15100-0D030 and 15100-0D031 (interchangeable with 15100-0D020, 15100-0D021, 15100-22040, and 15100-22041). Acting as the essential heart of your powertrain's lubrication system, this heavy-duty oil pump continuously delivers motor oil under steady line pressure to critical internal moving parts—including crankshaft bearings, camshafts, valvetrain assemblies, and timing chain tensioners—preventing thermal stress, premature friction wear, and low oil pressure issues.

Manufactured to meet or exceed strict original equipment performance specifications, this replacement pump delivers exact drop-in fitment, reliable pressure regulation, and durable operation for routine maintenance, oil pressure troubleshooting, or complete engine rebuilds.
