Question about 2002 Chevrolet Cavalier Coupe

Raised RPM's cause Engine Whine

Hey my 2002 chevy cavalier, 2.2L, standard, with no A/C, makes a whining noise when I put it past 2500+ RPMs. At idle there is practically nothing to hear at all. I have replaced the serpentine belt and the idle pulley, but the problem still persists. If you guys have any solutions they would be greatly appreciated. Thank you.

    I am supposed to SPIN the pulleys with the serpintine belt off, as in having the engine run, correct? And how can I isolate the noise of certain pulleys?

Could the whining be caused by a bad seal?


The power steering can whine or alternator. Get a rubber hose and put it on your ear to listen while putting the other end near whinning parts and decide for yourself. Worn bearings will whine.

Engine making whining noise


There are a couple of things to check. If your power steering pump is low on fluid, or a bad bearing is in the Alternator, they will whine. The PCV valve or any hole in the Vacuum lines will whine as RPM is increased. Even having the Air filter box not fully seated will make a whining noise.

Now both automatic and manual transmissions can whine as RPM is increased. Check fluid for each.

Serpetine belt and pulleys-can make noise.

Sometimes you can shift into neutral at any speed and the engine rpm will drop almost instantly as the car rolls at speed. If the problem disappears as soon as the rpm drops, then an engine part probably is the reason.

Power steering whine


The bubbles are more or less normal.
I would want to know for sure the noise is coming from the pump and not another pulley on the engine. When you turn the wheels you put load on the pump and the drive belt which loads the other pulleys too.
How about taking a long piece of heater hose and using it to listen around the belt while a helper turns the steering wheel ?

Can a dirty Air cleaner filter cause the engine to make a whine noise at low rpms. It goes away and cannot hear it had higher speeds.


pull air filter out and start car. does it whine? that should answer that question. i think its a pulley,power steer pump,water pump, idler tension. while engine is running be very careful and try to listen and look at any of those and see if any wobble or squeal, also make sure the belts are tightened and not slipping on alternator pulley. also could be the alternator whinning.with the hood up and car at cold idle i'm sure you will be able to diagnose.

I have a 2002 chevy surburban and it makes a whining noise.


the noise happens running down the road or parked? Is the car a four wheel drive? The alteanator can go bad and whine, the wheel bearings can go bad and whine, windows not fitting right can make a whine The altenator will stop whining if it's unplugged, if this fixes it the battery and the altenater need tested and a bad battery can make the altenator whine and it still be OK. Don't run the engine with the battery disconnected as this can blow alot of expensive stuff and the altenator.

Engine knock hard over 2500 rpm


Does the oil light come on or the knock occur during the engine warm up after a cold start?
There could be a couple of problems causing the issue. You could have an oil pressure pump or pump pressure regulator sticking. I would have a mechanical oil pressure gauge installed and verify oil pressure at idle and 2500 rpms to make sure oil pressure is in normal ranges.
You could also have excessive piston rod bearing, crankshaft bearing or cam shaft bearing wear that will cause oil pressure to drop too low to prevent the rod knock your hearing at 2500 rpm.
You said a knock and not a ticking noise,so I don't believe a lifter is the issue at 2500 rpm.
Start with the oil pressure check and go from there.
Let me know.

A high pitched whining noise in the engine.


This Noise Description sounds Indicative of the Sounds that come from the Serpentine Belt Or Related parts such as Belt Idler Pulley or Belt Tentioner witch also has a Pulley, but if Tensioner itself is Literally BROKE I've replaced a number like this it will cause a Whining noise . Best case scenario its just the Belt, and if any of the other Problems turn out to be the Culprit the Belt MUST be Replaced Anyhow as Damage is Being caused By the Very Whining you hear.
PLEASE Spend the Extras $ for the BEST BELT as this Drives your Water pump, Alternator, A/C Compressor, Power Steering Pump All Crucial to Control of, easy Steering ,All Electrical-Power Distribution, The COOLING of Engine << VERY CRITICAL Component
The Pulleys usually have a more Hum type Whining. So I would say at Best The BELT , And WORST Belt Tentioner is Broke

Continuous "whine" @ 1500 RPM only; and jerks/2001 Lincoln LS


Run the car from the top of a hill and let it coast at your whining speed. Put it in Neutral, does the whine disappear?
If not its in the drivetrain (wheels, driveshafts, tranny)
Very unlikely to be the timing belt. If it appears at a fixed speed then its drivetrain, if it whines at fixed revs its the engine.
Most likey the transmission I fear....Tires will also make loud whining noise too though...
