Title:
HEAT SHIELD RATTLE

Models:
'02 ES 300

Introduction

Under certain conditions, the heat shield for the catalytic converter on some 2002 model year ES 300 vehicles may be the source of a rattling sound. This rattle noise is most noticeable when driving at vehicle speeds above 50 mph, at which time, the air passing under the vehicle may cause the heat shield to vibrate and contact the body. As a result of this, the heat shield may generate a metallic rattle that sounds like it emanates from the dash or center console area.
