Parts for your 2013 Toyota Mark x-Oil pump

2013 Toyota Mark X Oil Pump — purpose, care, and when to replace

Based on Toyota technical documentation—the Toyota Electronic Parts Catalogue (Mark X GRX130/133) listing “Oil Pump Assy, Engine” under Lubrication, and the Toyota Repair Manual for 4GR‑FSE/2GR‑FSE engines (Engine Mechanical, Lubrication)—the 2013 Toyota Mark X is fitted with a crankshaft-driven, gerotor-type engine oil pump integrated at the front of the engine. It’s absolutely relevant to the vehicle’s operation.

This pump’s job is to push the right amount of oil, at the right pressure, through the V6’s galleries to bearings, camshafts, timing chains, and the Dual VVT‑i system. It keeps friction in check, carries heat away, and suspends contaminants until the filter grabs them. Without a healthy pump, the Mark X can cop low oil pressure, noisy cold starts, poor VVT‑i response, and eventual bearing damage—none of which is a fun time under the bonnet.

For routine servicing, the pump itself isn’t a scheduled replacement item
