Thanks guys

 

This sort of sounds like the noise I have been noticing from my Taco. However I have noticed that it is a lot louder when it is really cold outside. Is yours like that too?

I am thinking that its the belt, but it could also be a belt tensioner.

 

spray some wd 40 on each belt while its running,if it stops it's the belt

 

Hey Tacoguy - I'm in Chicago as well.. today's 24deg when I made that recording..

I noticed it the other day on the way back from work whilst stopped next to a concrete barrier.. then later on in my commute the sound seemed to have gone away.

Then today on my commute back, the chirp was there all the time, but then again my commute today was only 6 miles...

Does the sound go away after driving for a while?

Don't think that's a good idea.. wd40 will make it worse and might even damage the belt..

 

Mine does tend to go away after being run for a little while. Today since it seemed to be a lot warmer , it seemed to chirp less. However during the last couple of weeks of sub 20 degree whether, it has been chirping loudly.

 

could be because the belt is cold and does not want to expand as easily as it would if it was warmer out

 

A colder belt would shrink.. increasing tension.. a warmer belt is looser and reduces tension. We all know a loose belt would squeal.. not sure if this problem is due to that...

 

I'll bet its the A/C idler pulley.

Do you do any offroading or exposed to water ?

The A/C idler pulley is the lowest pulley and often exposed to more moisture causing the bearing to go bad.

It's an easy and pretty cheap fix. Years ago, the dealerships were selling the entire pulley for $35. I actually replaced only the bearings - but the grease seeped out withing 24 hours. So....you can't slap any-old bearing in there. It's gotta be a special bearing that can handle the Rpm ranges. I ended up buying a pulley from toyota.

 

sounds like what my throwout bearing is sounding like right now. but mine goes away if you slightly push on the clutch

 

yeah I got the bearing noize too now. see if it goes away when you press on the clutch a little.

 

Oh forgot to add that I have an auto... So how do I test that theory? Thanks

 

Did you really just suggest that someone spray a lubricant on an accessory belt?

Don't do this^^^ Try some belt dressing if you suspect the belt.

 

Sounds just like my truck, but mine is more red.

 

Mine squeaks right when I start it in the morning. I start it, go inside to get my backpack and phone and stuff, and when I come back out it's usually fine. I think it's just your truck complaining about getting up early when it's cold.

Yeah, since the temps have been a little bit warmer lately, my truck hardly makes any kind of chirping noises anymore.

 

Last week, we were below zero every day. Thank God we had snow days Wed, Thrs, and Fri or Taco would've been bitching all the way to school.

 

Oh yeah I know how that is. I got a prerunner, so RWD sucks in the snow. Although I got to admit, it is pretty fun in the snow!

 

I sprayed the belts with some Belt Dressing and the sound went away.. Hmm looks like I need to tighten the belt a bit? How do I do that?
