Default Whining noise with video, safe to drive?

This morning, started my car and drove it to work. Every time I drive it, I let it run for 1-minute to get warm. When I left work around 5 hours later, I returned home and proceeded to check the oil. When I popped the hood, I heard a loud whining noise coming from the somewhere around the alternator and the pump next to it. I want to know if anyone has had the same issue, and if the car is safe to drive.

Always let the car properly and fully warm. A motor does not like to pump cold oil through out the system while driving.

I always let my oil temp hit atleast 150 before driving

How would I check if the issue was one of those two? It was not making the noise when I started off last this morning.

I could see doing the waiting till the temp is 150 to drive in the dead of winter especially in AK but other than that just start it let it run for a couple min to get the oil circulating and then just drive it. Not hard for the first couple miles but easy then have at it.

You just plug it in if its under 20 out and auto start 15 minutes ahead of time if you live in south central Alaska or below. If you dont...you have more heaters, a better battery and more idle up time... or a garage.

You NEED to pop that drivers side timing cover off and look. Its stupid easy.

And check out everything else that rolls on the front of the motor.

Sounds like your power steering pump is the one making the noise. Check the fluid level in the reservoir.

You can take off your accessory belts and start car. Sound still there? Then it's a idler on timing belt. Sound gone? It's either alt, ps pump or AC tensioner.

Ok. Ill take those two belts off tomorrow and see if the noise disappears. If it the timing belt tensioner, then the car should probably be parked until its fixed right?

It can be driven. Just not far or high rpm. Its just a ticking time bomb and an expensive fix. If it is your only daily driver then drive carefully if think the bearings are not completely shot. But otherwise I would not risk it.

Well, I took off the AC belt and that seems to be the culprit. So I guess I will be getting a new compressor. Luckily the cold Colorado winter should be coming in soon (if it stops raining), so therefor I just removed the belt to stop the noise and the compressor will wait til 14’. Thank yal for your assistance!

Might want to replace the tensioner pulley first. Especially if the noise didn't change at all when the ac clutch was engaged. It'll be much cheaper so I'd start there.

Yal were completely right. I took the pulley off and the bearing looked like those "after-smoking lung photos" they show at elementary schools. Replaced and works great! Thanks for your help!

I was gonna suggest the power steering pump also like a few others but that's good you have it fixed!

This forum makes you post a few times before it lets you start a thread so this is a worthless post!

What would happen if you just simply removed the AC belt and drove around like that until you can find a new compressor if the issue IS the compressor itself?

You'll get no AC, should be fine to drive with no belt for however long you'd like

Ya I was having the same exact problem as the OP so last night I confirmed it was the AC idler pulley and it was starting to eat the belt up so I just cut it off and the sound went away. Ill be replacing the pulley with an oem one shortly tho. Im glad this was the issue and not anything else.
