High pitched noise

[nick3110]

Hey again ......

i'm here with yet another high pitched noise lol..

My Car:
VX Berlina S2 Auto 3.8

at around about 80kp/h when the car drops to 4th gear, there is a high pitched squeal at about 1500 revs, so pretty much keeping the same speed, maybe under more accelaration (exhaust takes over then haha), but when i take my foot off the gas the squealing stops..

i can sometimes here it when accelerating through all the gears, but once the revs get too high, drones out the squealing..

so yeh anyone know what this is?

Thanks

[nick3110]

also forgot to say, the brake pads have been replaced recently (to help remove the squeaking brakes, helped so much *rolls eyes*).. so it can't be the squealer things lol..

[spirto]

had a look at your idler pulleys? there should be two on your engine.
could be a bearing noise....?

or a fan belt? airconditioner one?
can you record the noise? and put it as a link on you tube LOL ahaahhah

[nick3110]

and how much would it cost to replace one of them? any mechanics want to chuck in known prices?

mmm... i didn't check if it was going on when my a/c was on or not.. i'll do that when i go out 2morrow..
i'll try n record it, but its a bit too quiet, so i'm not sure if my phone could pick it up..

and how much would it cost to replace either the fan belt or airconditioner belt too? just looking to see how much i need to save to repair ..

[nick3110]

also another thing to help diagnose.. it doesn't happen when i just leave it in park and accelerate..

Belt $30.00 for decent quality one (GATES) Easy to replace.

Pulleys $25 - $30 make sure you get metal ones. Easy to replace. Replace all three of them, one that sits next to A/C compressor, One on the pre-tensioner, and the ribbed one on top right of motor.

Tip for if your changing or taking off your belt.
Check if theres a diagram of how the belt is to go back on and if not make a sketch so when you go to put it back in you wont be there for half hour guessing through each possible way

[nick3110]

lol i'm guessing u've learned from experience.. :P

[vt s]

haha no doubt :P

When i did drive belt in my VT i sorta expected the diagram to be there and didnt check before i took the belt off.
And yea took bout 15 mins making sure it went back the right way lol

sounds like what i got in my vt ss mate
already done all the belts and the pulleys, squeel is still there for me
last thing to tamper with is my tensioner

[drift-it]

and if you didnt already know the tensioner is reverse thread!!!

well there isn't any harm changing them over anyway :P.. my car's full of squeals lol, so i'm sure it will help stop one of them lol..

ahm if its a squeaky belt and it keeps going after you replace the belt and the pulleys, i would check the harmonic balancer as it is one of the signs of a blown harmonic balancer, or a harmonic balancer on the way out.

got the issue fixed today, it was the front left wheel bearing.. the noise got unbearable after getting rear-ended 2 wks ago, so i went to a different mechanic took him a while to diagnose it, but he got there lol..

so yeh, thank **** for that lol..

i didnt even think to ask if it sounded like worn down brake pads.... sounds very similar to a wheel bearing.

Hey guys

I have a VT xu6 supercharged, well basicly my problem is squealing noise coming from the front of the car, 1st time i thought it was the pullys, i replaced them now it still does it even more, got told its a waterpump, changed that, squealing noise still there, its driving me crazy, now i think its the aircon clutch or something like that?? not sure so please help??? ..

[D-Man]

if yours is charged (i only assume from your name...) it's not the charger belt or the charger bearing?

bearings? could be the pulley's themselves as in the wheel.. not the belt.
check aircon belt and fan.
also does it happen when idling or neutral/park revving?

cheers,
