Hey everyone. I recently bought an ‘06 TL that now has 111,000 miles. Since I bought it with 108,000 the car has had a strange whistle/squeak coming from the engine bay. I believe its coming from the right side.

The sound only happens when the engine hits a certain temperature as its warming up. From a cold start the car runs normal for a couple minutes then starts the squeak sound.

if anyone has an idea as to what this could be your input would be greatly appreciated, thanks!
