98 gs300 loud screeching noise that last for about 5-10 seconds

I have a 98 gs300 I have noticed that whenever I stop and may even sit for a moment a loud screeching noise that last for about 5-10 seconds and then I smell smoke. After awhile no noise and no smoke. What could this be?

The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.
==== I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
==== Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.

Please post more info on the comment window.
I will follow up on it.

Belt noise when i start the car and it is cold. Last for about 15 secs. It has a new timing belt.


no engine stated, and this varies by ,, engine.

the belts , if new , screech for only 2 reasons
1: loose (or oil soaked, watch a guy last weak oil it to stop this)sad.
2: or the accessory its driving is seized.

id bet the cogged, timing belt will never screech, its idler might.
did you inspect all parts as you asssembled the engine.
no engine stated, so be hard for the blind to answer with savvy,
accurate answers, no?

ACCESSORY belts are tension'ed, 3 ways. (3 classes of systems)
1; manual tension. means you sit it to spec.
2: auto tension'ers
3: some look like auto type and are not.... the book for your engine tells all this.

the cam belt as special tension'g steps, did you follow those.
we cant guess what you did wrong.
nor if you even followed all steps.
below is technician loosing the auto tensioner
if the tensioner feels weak or bad, it is.
my guess, (useless) is that the cam belt is ok
but you skipped the accessory belts tension steps.
if it didnt screech before.451adf4b-5c25-45c0-9005-5e285b255e75.jpg

Car makes very loud screeching noise.


It could be that the air conditioning compressor clutch is not working properly. The clutch should allow the pully to freewheel when the air conditioner is not used.
You can have your battery tested at.an auto parts store, and you can test the alternator by removing a battery cable while the engine is running. The alternator is what powers all the electrical systems while the engine is running. If the engine stops running when the cable is removed, this means that the engine was running from the battery and not the alternator.
Your alternator or your regulator is bad.
Regulators are an internal part of alternators, unless its a pre 70's.car where they were a separate external unit.
Hope this is helpful.

My car makes loud screeching noise when starting.


could be your serpentine belt. usually when they get worn they will start to either slip or cause a very high pitched screeching noise. to verify that is the cause get some water or brake clean in a spray bottle and spray it on to the belt while the vehicle is running. if the noise goes away for a moment you found your cause. if not then its something else. Hope this helps

I have a Toyota Ist that i bought 4 months ago. The problem I have is the noise whenever I use the car brakes. I have taken the car severally to different mechanics (at least 5 times!!) and I am at my wits...


Well, when I have a screeching problem, I try to use Wagner Thermoquiet brake pads that have the shim built in, instead of standard ones.

They seem to stop more quietly than other brands.

The technicians that say that there is nothing wrong are probably just measuring the thickness of the brake discs, and the thickness of the brake pads, and maybe look at the surface of the brake discs for glazing, and don't want to replace parts unnecessarily.

So, I would ask them about this problem and see if they can install the Thermoquiet Wagner brake pads to rectify the problem.

ABS has more to do with pulsing 5 to 6 times a second when trying to come to a halt to avoid locking the brakes. I don't think that it is the cause of your screeching sound coming from the front.

Screeching noise when steering


These are your brake pads letting you know that you only have %10 left. There are little metal tabs that rub on your rotors when your brakes are low and cause a squeeling noise. Just replace your front brakes.

Loud screeching noise coming from car after stops.


the screeching noise is most likely caused by a slipping belt or pully. transmission probably needs fluid and filter changed.
