High pitched squeal on cold starts - 2007 RX 350
I have a 2007 RX 350 and for the past few weeks it has had a high pitched squeal during the first start of the day (car sits in my driveway overnight). The sounds like it is coming from right behind the front right/passenger side wheel. It is worse when the temp is colder. It will go away in 3-5 mins of driving and won't come back as long as the car/engine/etc is still warm.
I thought it might be the power steering fluid. So I took all of the fluid out of the reservoir (it was brown, so definitely dirty, and running low, well below the cold min line) and put in some synthetic Mobil 1 ATF fluid. I drove around a couple of days and the same sounds comes during the cold starts.
I only emptied/refilled the reservoir of power steering.
Any other ideas? Otherwise, I have to leave my car overnight at the Dealership and spend $$.

I got the same car with the same millage. checked pulleys they were in perfect condition.
bearing noise in most case will stay all the time. it doesnt matter its hot or cold
you may want to check tensioner pulley, but i give 100500 percent that this is a belt=)

Hi denimfake. Do you mean that you have an '07 RX 350? If you did change the belt recently, I would appreciate a few tips. Sounds like you removed the front right tire. Which bolt did you have to loosen to remove the belt? Was it a clockwise or counterclockwise motion to remove it? Also, after putting the belt back on, how tightly does the bolt need to be screwed back on?
Thanks for any help you can provide - I appreciate it.

Open hood, remove passenger side engine bay plastic cover, jack up car, secure it, remove passenger side wheel, remove small plastic cover that covers crankshaft pulley( 2 x 10 bolts and clip, find a belt tensioner( located at 2 o'clock from crankshaft) use 14 wrench turn it counterclockwise until hole on pulley match a hole on tensioner bracket, put an alien wrench to secure it, change a belt following diagram

Watch a video. It is same procedure on our RX. Make sure you get good quality belt.
No torque wrench needed, you gonna move tensioner pulley forward to release a pressure from a belt.
Just watch a video. It's everything there. Enjoy=)

Very unusual thing happened yesterday morning and this morning. Both mornings were a bit cooler, so I was expecting the squeaking to be louder (as it had been the previous days). However, now there is little to no noise. If before it was a 10, now it is at most a 2. Only thing I can think of is that it took the power steering fluid over a week to fully mixed in? (Since I did not do a full drain, merely just pumping out the reservoir and filling it back in).
I'll wait on the belt for now, empty the power steering reservoir and refill again.
