The purpose of the Lexus RX350 Oil Pump is to keep engine parts lubricated by pushing pressurized oil through bearings, pistons and cam surfaces to keep heat and friction under control. In every RX350, this Oil Pump bolts near the crankshaft, sucking in oil via a mesh pickup, forcing it past the filter and cooler and through to the galleries monitored by pressure sensors. Many versions of the Lexus use a crank driven gear pump, either direct drive hugging the crank snout or side mounted gear pump or chain setup, both manufactured for steady flow. Early RX350 models favored direct drive but newer ones use gear or chain drives, all aiming for roughly 10 psi per 1,000 revs to keep the dash light off. No matter what style the Oil Pump is, it uses a relief valve, which opens under excess pressure, and the pickup must be kept clean to avoid starvation. Performance packages in select Lexus trims with wider bearing gaps may be paired with a high volume Oil Pump to provide extra flow during high RPM stress. When a Lexus engine is rebuilt, the RX350 Oil Pump is stripped and the gears, housing and driveshaft are inspected to ensure that it resumes its flawless lubrication when reinstalled.
