Preparing For The 4LF LSC
Overview
Lexus is initiating a Limited service campaign (LSC). The 4LF LSC is for North American produced 2004 RX 330s. On certain early production 2004
model year RX 330 vehicles a crack may appear at the base of the radiator which results in the leakage of engine coolant. This bulletin provides all the
details necessary to plan and implement this LSC at your dealership. Key points on the LSC are summarized below.
4LF Condition
On certain North American produced 2004 model year RX 330 vehicles, a crack may appear at the base of the radiator which results in the leakage of
engine coolant. This occurs predominantly during cold climate conditions. Should this happen, there may be an increase in the engine temperature.
Ultimately, the engine may overheat and/or the heater may become ineffective.
4LF Repair
The 4LF LSC involves inspecting, and if necessary, replacing the radiator with an improved radiator. This Limited Service Campaign expires on October
31, 2007.
