There is a pressure relief valve in the pump that allows excessive pressure to bleed out and so not lock up the pump. This is spring loaded so I would be checking the spring tension as the noise may be the valve vibrating from repeated unloading of the pressure more rapidly than it should . It will go when the steering is being turned but will reappear when the wheel movement is stopped . As power steering pumps are the same as sump pumps ( 2 spur gears in a case ) they are mostly un repairable as when the case is worn there is excessive clearance between the teeth and the body and the teeth of the gears will have excessive back lash . As one gear is on a shaft and the other gear is driving from the pulley any misalignment will cause problems as the gears will tend to be out of mesh. It is always best to replace a pump with a new item and not reconditioned as they are seldom repaired correctly.

    the one thing that throws me off that at idle and while turning the steering wheel sometime the noise dessappears and then comes back feel like trying another steering pump but if i can get one off a engine that i know is good would elimanate pump

    When yo are turning the steering wheel the pressure in the pump is reduced as there is fluid motion and the pressure on the relief valve is less so it would not be working. I would expect it to come back if you held the wheel steady at a point as there would bo no more fluid flow so the pressure comes back fully on the releif valve.. Try what you say as it will prove one way or the other if it is the valve

Hi , aparentlyyour mechanic just dont want to check nothing else,any new noise should be checked before major damage may happens,the first noise sounds like the new timing belt is rubbing the cover because they removed the alternator and air conditioner belts to install the timing belt ,may be that they did not re install everything right the way it was.......

SOURCE: power steering problem, noise coming from engine, 97 montero

Your experiencing the same thing my 02 is experiencing- your crankshaft pulley is slipping on the crankshaft. It only does it under load, i.e. turning steering wheel(loads the power steering pump) running heater blower on high with headlights on (loading the alternator) or running the a/c with blower (loading the a/c compressor and alternator). Turning off all lights, blowers, ac, etc and allowing the car to idle should kill the slipping until loaded again. This problem is very serious and very expensive if your don't catch it early. It require repairs ranging from tightening the crank to pulley bolt, to replacing the pulley AND your crankshaft if it is allowed to continue. if you cannot get it serviced immediately then do your best to keep loads off of your belts by driving with the blower off, A/C off, and lights used only when necessary. Also try to avoid extreme tight turns which load your power steering pump. Your repair, if not done asap, will cost you upwards of around $3k since the motor must be removed and completely torn down to replace your crankshaft and pulley. I would seek a tech who will exhaust every other method- i.e. sleeving, welding, etc. to effect a repair. Just don't put it off because it will only get worse...

SOURCE: power steering noise

The belt is almost assuredly to tight and needs to be loosened just a hair. It is hard sometimes to get the tension just right. Try looseneing it a bit and hopefully that will help. I have had the same problem in the past.

SOURCE: can't change power steering belt on 2001 toyota echo

take a look some pullies are spring loaded and it may require a ( not recommend unless stuck) but a pry bar. if spring loaded is the case there should be a tool that you could rent that is use for prying the pulley.

Note: make sure to release slowly so not to damage pulley.

SOURCE: noisy water pump pulley,alternator pulley..timing belt tensioner

I have a 1995 xj6....same problem. I replaced the belts, water pump, and the alternator. Still does it. As I play with the tension on the belt (belt that drives water pump, alternator) it goes away and comes back. If I remove the belt, the metal to metal screech stops. I then, with just the belt, turned the main pulley on the front of the engine, and there was the sound! The main pulley has 2 belts that run on it. Also, 2 pulley tracks. They SHOULD move simultaneously and be super meshed. But the rear one moves on its own under tension until it warms up and I guess, the bushing maybe expands. Now.....how do I fix it??????

Why does my 2000 Toyota Echo misfire on left turns ?


It sounds like you have a wiring or connector problem in the steering column. I'm surprised your mechanic did not think to check for that.

Check the heater fan motor they have a tendency to have the shaft bearing wear out and make a squealing noise from time to time depending on how the shaft wobbles and that is the reason you don't hear it when the heater and ac is off.

Toyota Echo manuel transmission noisy


Check if:-
- It is squealing or squeaking noise, the thrust bearing is at fault and need to be replaced.
- The noise varies when accelerating or decelerating, check the engine mounts and muffler Re torque all the suspension nuts and bolts. Also have a look in the engine bay area for any loose component.
- Noise is heard in any particular gear, then the transmission may require major repair.
- Check the transmission oil level.

Whistling noise coming from engine compartment on 2004 toyota sequoia


Troublkeshoot possible noisy idler pulleys, if they are OK, remove the plastic cobers & check for a noisy timing belt tensioner pulley. Water pumps rarely "whistle"; they grind. But, if you see any evidence of leakage at the weep hole on the water pump impeller shaft, replace the pump regardless. Might as well replace the timing belt whilst you are there, too.
