Without more info. All i can suggest is get a stethoscope, or lenght of rubber tube, and place in vicinity { BE CAREFUL} of noise. Shine light & see if you can notice the pulleys { where the belt goes] moving smoothly. Notice any pulleys that may be moving a bit erratic at idle

Whining noise at speed 35/40 left front side wheel 2000 infinity qx4


Try driving at 35/40, so you can hear the noise, try swerving (just a little) to the left, if the noise goes away, when you swerve, you most likely have a bad wheel bearing on that side.

ENGINE WHINE WHEN HOT AND DRIVING


Could be several things.
You could take a section of heater hose and use it like a stethoscope to listen for the noise while the engine is running.
Once you narrow down the location you could take the belt off for that accessory to confirm.

Only when it is hot out a loud humming noise starts in the engine


I suggest that you open the hood (when the engine is hot) and try to pinpoint the source of the noise. Check the power steering pump- these sometimes make a noise that could be described as a hum or whine. The alternator and belt idler or tensioner are other things to check. An automotive-type stethoscope might be useful for tracking down the noise.

I have a 01 ford escort zx2 and it is making a whining noise from under the hood i have replaced the water pump and it still whines and the heater will start off blowing hot air but when you go several...


Remove the serpentine belt and run the engine to see if the whine still exists. If the whine is gone, try moving the pullies by hand to feel what pully is rough or has a lot of play. Your issue with the heat is likely separate from the whine. You have air in the cooling system. With the engine cold, remove the radiator cap. Fill the radiator to the top and run the engine until it gets to operating temp. The level in the radiator will drop, this is when you add more coolant and replace the cap. Make sure your overflow/resivoir bottle is half full with coolant.
