What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

Loud whine coming from engine


The whining sound that you here could be coming from a number of places. It may be a coincidence but I think you may be talking about the transmission's pump. You may want to buy a stethoscope. This tool, if properly and carefully used, will help pin point a mechanical noise. Other possibilities are the power steering pump, tensioner and idler bearing, A/C compressor or A/C clutch, or Alternator. I hope this helps, write back if you have any other questions, good luck.

01 ford escape w/ 185,000 miles. warning sound of 5 consecutive dings then pause and a few minutes later, 5 more, and continues to do this at various times and then sometimes it doesnt do it at all. ...


The dinging from the dash is the Air bag system check. Check that the bulb in the dash isn't burned out. The stalling and spitting could be clogged converter. Check how much exhaust is coming out of the tail pipe when you rev it. The smoke could just be from a leaking valve cover gasket.

Whining when i press gas


normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Same problem: a high pitch whine after extended driving


Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).

A constant whizzing


that whining noise is definately your power steering pump. the earlier models eg 2001-2003 just have noisy ones. so they say, if that noise become really excessive; its an early warning that its gonna fail. the newer pumps are much quiter, but i was quoted approx 1200+ CND for a new pump. I have a 2003 cooper, and the whining noise is loud. only once has the steering been really stiff, but i resolve that problem by restarting the vehicle. watch out tho, the power sttering could fail on you while your driving around a corner, and if you dont have both hands on the wheel, you'll go strait.
