can't figure out what this noise is. took it to the mechanic twice and they couldn't hear anything. there's a high pitched noise coming from the car that you can clearly hear in the video. any idea what this is?

about car: 2014 honda civic CVT with 25,000

last time i took the car to the mechanic they said the idler pulley, belt and tensioner looked OK. not sure what that means.

Take a meter-long piece of heater hose or garden hose, and hold one end against your ear. Use the other end like a stethoscope and carefully place it near various pulleys, belts, air intakes and exhaust.
Be careful near the fan and hot exhaust. You can put a small funnel into the hose end toward the engine if you like. When you find the location, get advice or edit question if needed..

  • can you hear the noise or nah? – nachos Dec 16 '18 at 2:56
  • I only hear rumbling, tapping, and mic noise. But if you hear it, track it down and let us know the location. – John Canon Dec 16 '18 at 5:54
  • at the end of the vid it gets extra loud. its kind of subtle. its like a very high pitched whistle noise almost. i wonder if its just too high frequency for some ppl to hear it? – nachos Dec 16 '18 at 6:41
  • Find the source. – John Canon Dec 16 '18 at 8:38
