Timing belts

Here is what Lexus recommends: On 1998-2003 models, replace every 90,000 miles or 72 months. According to my database the 3.0 V-6 is NOT an INTERFERENCE engine, which means if the belt breaks there will be no damage to the engine, however, It would be better to replace it than calling a tow truck somewhere at night, far from your home. Timing belts has the tendency to break at the worst possible time. Zee

Yes do to the age of the belt, it could brake and you would have engine damage

GENERALLY YOU DO NOT NEED A NEW TIME BELT TIL 90,000 MILES.
