PART 2 Video - Weird engine noise

[1stE53]

I would try the belt first, but to me it sounds more like a pulley. Belt would need to be changed anyway. Did you have any solvents or cleaners fall on your belt? Like I mentioned earlier, I cleaned my engine and got the same sound until I put some baby powder on it over night. Did not go away rite away but its all silent now.

Idler pulley. My pick up is doing that and my buddies 05 4.4 is doing the same. My vote is the Pulley.

I know! My kids actually learned quite a good amount of it when they were in Moscow for almost a year. My best friend is Slovak, then I'd be able to talk to his parents as well Of course, I still need to learn Italian/Spanish for my local friends...I've definately got a to-do list in regards to learning other languages! In the meantime, whenever my friends start talking in their native languages, I yell at them to turn on the subtitles or speak English

There's no need to remove the engine dressing cover. Just take the smallest bottle of dishsoap that you have around the house, start the car, open the hood and try to squirt a little stream of it on the belt...preferebly on the grooved side of the belt. If the noise stops, you've found your culprit.

If it doesn't, then watch the tensioner to see if it's hopping around like I mentioned above. If it seems to be holding the belt nice and taught, then shut off the engine and pull on the belt near the tensioner, it should be nice and firm but have about an inch or so of give if you really tug on it.

If the tensioner is nice and firm and isn't hopping around, then I'd suggest to startup the engine again and spray some WD40 onto the pulleys where it bolts to each accessory (alternator, waterpump, etc) and see if the noise changes...just make sure to not spray so much that it splatters all over the place so you can keep it from getting on the belt.

Once you isolate the noise, spray down the engine bay around the belts to rinse away the soap, go ahead and replace the belt regardless (due to your mileage and any potential WD40 splatter if you had to spray the pulleys) and then replace whatever parts as needed. Replacing the tensioner and/or belt is quite easy, it's just a tight area depending on if you remove the fan clutch and blade or not. Personally I just wiggle the belt around everything, but I've got the fan clutch tools if needed.
