2004 Lexus LS 430 Service and Repair Manual

Fitment for this 2004 Lexus LS 430 service and repair manual is locked to the one powertrain the car was built around, the 4.3L V8 (3UZ-FE), so every clearance, torque value and service interval it lists is what Lexus specified for this model year rather than a figure averaged across the LS 430's production run.

Known issues on the 2004 LS 430. Two recalls are on federal record for this model year. The first involves the fuel pump: the impeller inside the pump may have been improperly molded due to a manufacturing error, and alcohol in some fuels may deform that impeller, a condition that could increase its rotational resistance. The second involves the automatic transmission: when the accelerator is operated quickly, a small piece of metal may separate from a retaining collar located in the inner part of the transmission, which may cause the parking lock system to be inoperative. Owners have filed 36 complaints for the year and Lexus has issued 44 technical service bulletins. The diagnostic and repair procedures behind each of those systems are here.

Whether the job is a fuel delivery diagnosis, a transmission inspection or a scheduled service interval, it holds you to the OEM procedure and the correct specification for this 2004 LS 430.
