SCrreeech

[husaynkhan]

Hi dearest members, my greetings. I have a Yaris HB ,auto year 06. Since i have bought it , every morning i starts it, it screeches for 11sec and then it starts. I dont know where the problem is? Can anyone help me.........:iono:

Is it a grinding screech or a high pitched whirring screech

[WeeYari]

My guess for a screech would be the serpentine belt. Since it is an '06, this belt has either stretched and needs to be re-tensioned, or it has reached end of life and needs replacing.

[detroiter]

Yeah, could be the belts being old and worn with moisture on them.

[big lo]

Yep, I agree the its the belt. First check the belt if its worn or a bit torn change it but if its good then you can loosen the alternator a bit to tighten the belt, good luck buddy

[husaynkhan]

wooow thnx for ur reply but when in the morning when am going to start the car for the first time, it does that grindd for 11 sec and then starts. Its an 06 car,auto.
so if someone can tell me where this belt is found or any image to show. it would be of great pleasure.

[husaynkhan]

or is it the timing belt?

[big lo]

Nah man its not the timing belt, just look for your alternator belt you only have one that is visible push down on it and you will notice that the belt is not tight and just loosen the alternator screw and tighten that baby up and that will resolve your problem

are you saying it takes 11 sec before it starts, and while it's trying to start it makes screeching noise?

[Betrivent]

Our cars have timing chains, IIRC. At least, all the japanese made ones do.

reading over husaynkhan post it sounds more like a starting system problem.

[marcus]

its just the belt...try belt dressing,,or just replace it..but make sure you get someone to do the proper tension eitherwise its still gonna squeel even if its new..

[big lo]

Ain't that the truth, I hope he does the job instead of paying someone to do it its simple even a cave man can do it lol

[WeeYari]

it does that grindd for 11 sec and then starts

are you saying it takes 11 sec before it starts, and while it's trying to start it makes screeching noise?

This is what is now making the OP's original post confusing. If the noise is occurring before the engine has even caught, then the belt is not the issue. If the noise occurs for 11 seconds after initial start, then we are still looking at a possible belt issue.

OP - please clarify when exactly you experience this noise. Also, you have described your issue as both a 'grind' and a 'screech'. Which is it? The belt will not cause a grinding sound.

o.k, so it takes 11 sec for the engine to start and while it's cranking over it makes the screeching noise, now once the engine fires up does the noise goes away or does it continue making the screeching noise.......if the noise stops it's probably the starter and not the belt.

[big lo]

I think Dark age 53 hit the nail on the head, I say its the starter as well as its was more specified by the OP and wit the help of dark53 to get this issue fixed so we can sleep better. Still thou we need a VID to get to the point at hand just to make sure.

[husaynkhan]

if its the starter then

[big lo]

Then change it man, that is a twenty min job

[DARK AGE 53]

if its the starter then

maybe have it bench tested before buying a new one.

[husaynkhan]

can anyone give me apic of the starter......thnx for ur supports
