Bussey Posted January 14, 2005 Share Posted January 14, 2005 I am experiencing a loud whistle on my RX 300 at initial morning startup. It lasts for 3-4 seconds and then disappears. Since that is the only time it occurs it is impossible to trace. I have checked for loose hoses, etc, and wonder if it could be belt or water pump noise. I have 102K miles and have had all required service done at Lexus but reside 2 1/2 houes from the nearest dealer. Any suggestions? Quote Link to comment Share on other sites More sharing options...
RX in NC Posted January 14, 2005 Share Posted January 14, 2005 What you're describing is typically caused by a worn-out belt. If you still have your original Alternator/AC belt on your vehicle, you can almost bet that it's the culprit behind your start-up noises.

Bussey Posted January 16, 2005 Author Share Posted January 16, 2005 Based on your suggestion I checked my service tickets and all belts have been replaced. I use belt dressing (spray) on my kitcar (Pinto 4 cyl) which makes noise on start up so I sprayed alittle on the Lexus AC/ALT belt and haven't had the nose since. Thanks a million!
