My 2000 LS400 has developed a "howl" in the engine compartment. It is mostly noticeable at low RPMs -- I can feel vibrations as well as hear them. My mechanic replaced the fluid coupling with a new Lexus/Toyota part (not the "tow package" version), but the howl persists. I can hear the howl under the hood, especially when I remove the plastic trim parts between the radiator top and the grille. I'm wondering whether the serpentine belt (which looks OK when running) is making the noise and vibration. Any thoughts or experiences?

The washer fluid lamp is on again on my 2000 LS400. I briefly disconnected the battery to reset it a few days ago, but it has gone on again despite the reservoir being full of fluid. How can I repair it myself, or just defeat the sensor it so that the normal dash display returns? Thanks in advance for any help. Wally

Thanks! WinoWally

Good Afternoon. I am looking for a source for the chrome wheel center cap as shown in my attachment. The cap is chrome plastic with a gold logo, and fits my 2000 LS400. I lost the emblem, but still have the original cap. Several sources offer a cheap knockoff, but I've been unable to find the genuine article, including at the discount dealership in Texas. Any clues? Thanks for any help, WinoWally
