    Just started. It went away for a second then came right back. Haven't had time to take it apart. Will investigate in the morning. I've included a link to the video in my Google Drive.

    Hopefully on of you fine members know what this is off the bat and I can find the part and slap it in straightaway.

    Thanks!

    Edit to switch to youtube link.

    If the car is off and you push on the throttle plate with a finger to open it, how does it feel?

    Does it move sort of smoothly, and feel as if you are whirring a little geared-down motor as you are doing it?

    If you unplug the throttle body electrical connector and turn the car on, does the same noise happen?

    Will check in the morning. Did take a little spin after the car cooled down tonight. Overheat light came on. I think it's the Water pump. Will also check in the morning.

    Okay, replacing the radiator and one of the hoses, before Reinstallation came undone on the opposite end. It is a small tube that connects to the driver side top of the radiator and I tried to trace the shape of it down to the location where it connects, but I can’t seem to find the place where it goes.

    So that was a day. Radiator replace.

    Turns out, it was also the water pump. I did order one from Amazon but I did cancel the order after the fact. Also, it currently still says it’s on its way. We’ll find out tomorrow.
