Hi Everyone!

My 07 ES350 is experiencing some engine noises. It kind of sounds like a bird chirping noise, from a belt possibly?

My local Lexus Service center wants $215 to look at the issue. The car has 108,xxx miles on it.

I went to a few mechanics, and I’ve heard a few different responses. One being my IDLE or A/C Pully another mechanic said it’s my water pump and the third mechanic said it was my alternator.

Any tips on what this noise could be? I found a local mechanic that works on Toyota and Lexus only, I’ll be taking it to him sometime next week to have a look at it.

 

One of the idle pullies.
You have three. I never replaced them, just the bearings.

 

Would I have to change the pully, belt or both? Any idea how much I should pay for this job?

 

I never changed them, only the bearings.
If you don't have the tools to do it yourself then get the idlers from Amazon or ebay and find a mechanic who can replace them. You don't need to replace the V belt.
