High Pitch Squeal

[Chookie!!]

Hey,

When i seem to start the car, every now and then there is a high pitch squeal, it goes away after a a min or two, but when the car is under full throttle the noise comes back only while the accelerator is down?

not sure weather the timing belt would be causing this or its just a different loose belt?

any help before it goes to the mechanics again

my money is on the alternator belt. easy enough to nip up yourself. that also runs the water pump so dont want that slipping and breaking. just inspect it isnt polished and cracked then do it up a bit

[Johny Bravo]

my thoughts exactly. Most likely a belt. Is it a whiney squeal?

[Chookie!!]

Yeah it is a high pitch squeal/ whine

If it is taking a lil to start when the key is turned that would be the alternator or startermoter?

Drove perfectly till I got the thing home 2weeks ago now shit starts to go!!

Most likely the belt on ya starter motor. Like t revs said, have a look at all ya belts, if its frayed or cracked or just plainly looks crap. Change it over for a new one!

Hey

is the noise coming from cam gears? Coz I got that noise coming from there, get it while my car is idle and driving?

Bump

haha you're pretty f**ked if it's coming from the cam gears

i highly doubt your car is stil driving if it's actually the cam gears, it might sound like it's coming from there but it would be a belt

Reviving an old thread for the sake of not creating a new one.

I also have this loud, high pitched squeal at startup, but it goes away after a minute or two. All belts are tight and in good condition.

I can't seem to figure out what it is and I don't want to start replacing belts prematurely. Does anyone have any ideas of what else I can check?

Probably the alternator belt because the starter motor has drained some of the battery and the alternator is recharging it. If it squeals on every start up then take the belts off one by one to find the squealing belt.

You didn't spill any oil on them did you?

if they still squeal after being tightened then try some soap on them

Won't taking each one off individually be bad (even for a short while) since some of them run essential items?

It sounds like a small pig being stabbed

that's a bar of soap too, not out of a squeezy bottle - lol

Not the ancilaries. Cars can run without power steering and a/c and the alternator. Its advisable not to run the engine for too long with out the water pump, probs best to do this one first when the car is cold.

Its almost certainly the alt belt. I replaced my belts with shorter than recommended (845 instead of 855) brand new gates belts, the tensioner is almost at maximum adjustment, and its still squealing. Its like Nissan makes super slippery pulleys.
