Vitz 2006 FL 1.3L, 2SZ engine problems

[waleed2409]

you need a proper automotive stethoscope to identify the source of noise

Ok i checkd the origin of the noise n it seems to b comming from this bearing. Or wats behind this bearing. I think its waterbody. M i right?
N now wat to do? Shud i replace it? N how much will it cost me? Approx

Thts strange actuallay. Cz i installled this assembly with bearing n the fan type rotary thng which i think rotates the water. N the noise subsided for a min but again came back. So i again put my own back n returned the assembly back to the shop. I did this all in one go. I mean i didnt install it n drove the car. Just installed it. Put the belt back on n started the engine to check the noise. At start i thought tht the noise was gone but thn i listened hard n it was still thr. May b it was lesser but didnt go away cmpletely. Is thr anythng behind this assembly tht might b causing the problem?

Thats the water pump and you need to replace it

[syncview]

get a gmb water body
it costs about 2500

[waleed2409]

I replaced this part as i already said in my last msg. But noise did not go away completely.
Can thr b a problem with my water pump cover?

[waleed2409]

Replaced this part. But noise didnt go away cmpletely.

@waleed2409 ,
Brother I would suggest u check the belt tensioner. I had the same problem in my Civic.
I took it to honda people and they changed the Belt tensioner because of a faulty spring.
When u take off the belt so tensioner doesn't work so noise goes away, I hope it helps =)

It can be the timing belt. If the its kachr kachr sound at a specific rotation. Or could only be a pully bearing. Get is checked. Or else simply open the bonnet and try to find if the voice is coming from the timing belt or not.

Wats belt tensioner? R u referring to adjuster bearing?

Bro the sound is like kachr kachar n at idle RPM. At more RPM is vanishes as if the rorating part has gained momentum n its rotating smooth. But if its timming belt thn it shud not ho away when the serpentine belt is removed.
N also it appears to b comming out frm water pump. But thn i removed the water pump.
How can i check if its timming chain?

@capsat. @syncview. I replaced the water pump but noise didnt go away cmpletely. Can it b a problem with water pump cover? How to b sure?

sorry my bad to quote the timing belt, Toyota engines are coming with a chain now, Well this voice was in my 2001 Vitz (198,000) driven. Earlier the voice was low didnt take much notice, then changed the pully bearing still the voice was there.
Similarly as you installed the original one back again

The it got worse my mechainc still wanted to try and this time he told me is bar b nae hua to its definetly the timing chain. then after a month got it replaced finally the expence was around 24-28 thousand. some gears, timing chain etc were changed the car is smooth again.

it used to go like khachr ---------- kachr -------- khachr ----------- at every rotation and used to go away or wasnt audible when driving,

The other belt ur quoting to, Is the fan/AC belt? that should only cause sqeeking sounds if its teeth are worn out or it its slightly loose. you can put some (sure water) or grese to make it better.

[waleed2409]

My engines noise goes away when the fan belt is removed. If its timming chain thn it shud not go sway. M i right?

Waleed, we all can under stand ur frustration with regards to annoying noises while the engine is running.

Earlier, I had suggested you to identify /check the A/C compressor clutch pulley assembly for the cause of noise. I am not sure if you have done that.
I would like to suggest a test in this regard as below:

1) start the engine. (Vehicle in neutral)
2) Ensure that you can listen to the noise you are talking about.
3) Switch on the A/C blower with A/C compressor OFF.
4) Now switch ON the compressor and observe if the noise has gone or reduced. If the noise is reduced or vanished; it is confirmed that your A/C clutch pulley assembly is causing the noise and needs replacement.

Could be Alternator or its bearing too....it is also connected with the same belt....not only water body..

Cant tell, On the same side have you tried replacing the fan belt?

One more thing, When the fan belt is removed this pully isnt working i guess, So this could be the culprit to as my mechanic changed this pully before anything

The alternator sound is more like a whining sound, And it doesnt usualy comes with a specific rotation its their continuously.

how old is the serpentine belt ?
