Slight chirping noise when driving. Goes away if I get up to fast speeds

The title says it all. Trying to figure out why my old girl is making this chirping noise. Sounds like it's coming from the engine. Had to different mechanics look at it over last 2 weekends...found nothing wrong...they both thought it was radiator fluid leaking onto my belts...had radiator replaced so I'm not leaking anywhere but the noise still continues. Had all belts, hoses, wheel bearings and joints replaced over the last 3 years.

What is this noise?!?

 

I had a whistle that came from the seals under the hood. I put a 1/4-inch tubing in the black seals by the lights and hood, and it worked.

 

Is it the same belt that got wet with coolant? Sometimes when they get sticky with coolant they'll never fully quiet down, even after drying out. Might just need another belt. But check all the pulleys with the belt off and make sure they're smooth and quiet

 

I'm not sure. It may very well be. But I'm not even sure the noise is coming from a belt...seems like it is tho

 

Chalkboard chalk sometimes helps if it’s a belt. Stay away from belt dressing. I have yet to see that stuff work. Noises are hard to find sometimes for sure.

 

Only one way to tell, take it off and go for a quick drive
