Chirping noise in a Lexus ES 350 2012
Hi, I have a 2012 Lexus ES 350. When driving at steady speed without reving the engine there is a chirping noise coming from the engine part, like a cricket stuck somewhere, when pushing on the gas harder the noise is going, the same goes when releasing the accelerator fully. Any ideas what could be the noise? I would appreciate your help.
Well I finished the drive belts or something they drive like an alternator bearing. Define the noise see my video finding the source of car noises Scotty
Since you have already checked the serpentine belt, seems like it could be just one of the pulleys. Should be an easy fix.
With all the driven pulleys, idler pulley and tensioner pulley, it must be one of them. You said "they checked the pulleys as well." Who, exactly was "they?" Try turning your headlights on, if it chirps, it's your alternator.
Thanks for the video, I’d start with checking your cabin air filter (and then blower motor) for any trapped dirt/debris.
You say that the noise only appears when driving >30mph correct? Can you tell if the noise source is located inside or outside the cabin?
Have you changed your engine air filter recently?
