Squeaking at idle
So I have this squeaking noise at idle, but it seems like its only there (or mainly noticeable) when either the A/C or heat is on. Is it the tensioner?
#6
Advanced
Hey Guys, I've got an 06 TL with around 57k on it. Started having this exact problem about 2k miles ago.
After much research here on acurazine, I also came to the conclusion it is the tensioner pulley wheel.
At idle, when the AC compressor kicks in, it must put more resistance and tension on the belt, and then you can physically see the pulley wheel vibrate back and forth quickly as it makes that chirping noise.
So I'm wondering - can this be a simple DIY repair? Is there really a need to replace water pumps, oil pumps, timing belts, etc for just a bad pulley wheel?
Thanks!

This is weird but I actually had a noticible high pitched noise AFTER replacing the two belts (not the timing belt).
Is this normal ? Should it fade after a bit of "breaking in"? Before the replacement, the engine had no noticeable idle noise.

Any idea on the part numbers? Should I go OEM or will after market suffice? (autozone or equivalent?)
Also, the noise seems to subside once I am driving .. why is that?

#2 is the belt tensioner assembly including the pulley. #3 is the pulley by itself. I don't see the idler pulley though.
Aftermarket parts will be fine. If you get a choice between cheap and not so cheap, go with the not so cheap, usually it's a better part with a better warranty.
As for the noise going away, the faster engine speed creates a higher pitch whine, one human ears can't detect but get the dog and see if he/she winces when you rev the engine.

I recorded two short videos from my phone to show you guys what I mean.
Don't mean to thread hijack, but I think others may benefit from this and I'd hate to make an identical thread.
The car was parked in both videos. In video 1, I am just showing you what I think is making all of the noise.
In video two, the car is still in park and I am turning the wheel. The noise increases as I turn the steering wheel left and right.

I think it's howling when you turn the wheel because the power steering pump puts a load on the belt when you're turning. The bad news is that since that belt only runs from the power steering to the crankshaft, your power steering pump may be on it's way out. Have you checked the fluid?

Mine too.
