Screeching Sound

[Hoppe]

Noticed that some cars seem to have some screeching sound (sharp noise) when started up.

The sound will gradually go away.

 

What is the cause of this screeching?

[Fortress]

The belt is loose or wet. A common sign of wear on the belt. One made tends to do this is the Swift, pardon me, based on my own observation.

Yes, my Kangoo got diesel leaking from the fuel injector which is directly over the accessory belt that drives the power steering, etc. As a result the belt got diesel fuel all over and it screeches until the belt heats up.

Be a little careful, hopefully it does not catches fire. Anyway of sealing it up using glue(a gray plaster type), used to do that on an old car of mine.

hmmm, what belt?

Timing belt? Air-con compressor belt? Alternator belt?

I saw a Toyota Picnic the other day that screeches so badly until my ears ache..haha.

Previously I also have this problem. Later discovered that the bracket of the power steering pump had been modified by the previous owner, so the alignment of the pulley is out. Like you're described, the noise will go away after the engine warmed up.

 

Later changed back to the original bracket and problem solved.

the only belt not exposed is timing belt. ie the rest.

What if the screeching sound only come during reversing when I turn full lock to the right? Keep hearing this on my Sunny... Anybody can advise?

hey bro i have the same problem as you. i have a screeching(actually more like hissing) sound when i full lock right or left during reversing. mine's a lancer though

[Luckcent]

this type of sound maybe from the power-steering pump. Ensure to check that the pump has enough power-steering oil.

If its during turning, it could b the drive shaft rubbing against the axle. But its mostly found on old cars.

I tink for more accurate solutions, u shld go to workshop or back to dealer for professional diagnoiatics check...

Does the hissing sound, when you full lock the steering to one direction, also appears even if you are NOT MOVING ?

 

My Optra has that too..

[Cheeze]

yupz i've checked the pwr cteering pump, it's still full

[Cheeze]

mmm, ya come to think about it, it does hiss when stationary too.
