    2014 Mirage ES Whining

    I've taken my car to a few local mechanics and had a few belts replaced, but non seem to be able to fix my issue. These problems have been present since I bought the car in Jan 2019. I'm hoping a collection of mirage enthusiasts like yourselves will know something they do not, and to learn more about my car in the process.

    My car, a 2014 Mirage ES, 4dr Hatchback 5M, squeals/whines seemingly at random but there is a pattern (More Below). It can almost be described a a warble, like a bird, but a really annoying and ugly bird. I also experience a jerking motion during some accelerations, from light bumping to violent head bobbing.

    The whining varies in volume depending on the temperatures outside, the weather, rpm, and if the A/C is off or on.

    The whining is most present on hot days, dry days, and cold humid days (not cold rainy days, yes on hot rainy days)
    Turning the A/C on makes it louder, or on days when the whining is not present it makes it present
    It is present when idling (loud), and the volume scales between 1000(whine) and 2000(squeals) rpm (1500 to 2500 with the AC on) getting louder with higher rpm
    It stops at rpms over 2000 (2500 with the AC on)
    If I put the car in park it gets quieter
    On days with low to no whine, I experience the jerking issues mentioned above. Can't think of a day I have had both issues at once.

    It comes from the engine compartment, I have heard it with the hood open and the car idling. Front brakes are brand new.

    I will try to record audio if I can today.

    Edit: I ordered the belt 6pk1240 today, and will install it as soon as I can. Until then, here is a video I took of the engine while idling in park with the AC on.

    Thank you all for your help! I'll update yall if it fixes it or not, hopefully soon.

    Edit: I replaced the belt with the 6pk1240 and so far I have had better performance and no squealing, on the two drives I have taken since. I compared the old and new belts and they appear to be the same size and they both have six ribs, so I'm not sure what the issue with the last belt was. I have a new rattling noise that was either not there or was masked, sounds exactly like Fummins' engine down below. I couldn't "tune" the belt (I am tone-deaf) but I followed the 45-degree rule. I guess the mechanics around here are just using ****ty belts? Lmao

    I just figured out an annoying noise on my car. Turned out it’s the exhaust. The joint at the front of the cat I believe. https://youtu.be/_RA8EBNI0H4

    The AC is on when defrost is on, just to help narrow it down. Belt tension is worth a check first.

    Did you discover a fix for the rattle? After fixing my belt I now have the exact same noise coming from my car!

    Yup. It was the joint where the Catalytic converter bolts to the exhaust manifold. I removed the bolts, gobbed the exhaust gasket with a little bit of copperish brake lube and bolted it back together. Quiet as a mouse now. I swore it was a pulley or belt but nope.

    If you ever suspect it is the belt making the noise just take a bar of soap and touch it to the belt when the car is running. Of course, be very careful when doing this.

    If the squeak stops, you know it's the belt. If it doesn't, keep looking. As a bonus, your engine compartment will smell fresh and clean for a few minutes. Learned that one from my dad!
