	Don't take this the wrong way skanders, but I would advise against working further on your car until you understand what you are doing. You could be doing more damage than good. However, if you are feeling in a fearless mood, you can establish whether the part that you have worked on is the power steering pump by checking to see if there are pipes going to the steering rack. If so, it is the ps pump. The oil that dripped out should also be a different colour from the oil in your engine (usually red) I've never heard a worn ps pump clatter before as they usually whine, but I could be wrong. Once again, if you want to determine whether it is this unit that is cauing the noise, isolate it by removing the belt. Also, what do you mean when you say you opened the pump? Most PS pumps tend to be sealed units nowadays. I can't really make out what the unit is in the pci above. Edited by LuxAuto

	Yes it is the power steering pump the noise has stopped but the fluid is low and i have to power steering. But now since putting the rad back in the car is overheating again as it did before but was fixed replaced the thermo, coupling, definately have to be an airlock.

	if the system was not overheating prior to you removing it, then it is an airlock.

	Yes solved that but would low power steering fluid cause an all mighty screeching noise when the revs are above 2000rpm cos that is what it is doing now but when the car is idling its ok no noise

	If you are getting a screeching noise when you rev the engine (a noise like wheel spinning), then it's the drive belt (either PAS and/or alternator). It's probably worn and will need replacing. Examine the belt for cracks and wear along the sides. If the belt is OK, examine the pulleys. It's difficult to give you detailed advice because I don;t know what you are doing. You are jumping from one place to another and not updating as you go along. Tell me what you have done (from the beginning) and I'll do my best.

	What is your current problem? Lets start form there instead.

	Ok my current problem is that i am now getting a whining noise from the engine, as i have explained in previous posts that i was originally getting a rattling noise and some suggested that it was the oil viscosity so i drained and topped up still the rattle remained took the belt off and it went away no more rattle inspected the water pump and it was ok decided to go for the power steering pump and took it out it sounded a bit rattly like something was moving around in there so popped it back in and then started the engine no more rattle but now a whining noise as explained in the next few steps as and when and how it happens - When it is idling below the 1000rpm mark its fine no noise - But when u step on the accelerator and up the revs it starts to make a horrible whining and screeching kind of noise when it is above 1000rpm and above - Dont think it is the belt as i have checked it and it was fine - Made sure the belt was'nt coming off or off position seemed fine. - Power steering fluid is low so i am wanting to know if this would make that horrible noise i have no power steering and turning the wheel is almost impossible if you guys want arms like arnie forget the gym come and steer my car lol - any ideas sorry for the mixed posts but i am totally stressed

	OK, first thing, if you are low on power steering fluid, don't start up the engine again until you've topped it up. You risk damaging both the pump and the rack if you run it with insufficient fluid. Once, you have bought some fluid, top it up as necessary and then bleed it. Not sure about BMWs, but the beelding process should be the same no matter what car you drive. Leave the cap off the reservior and turn the steering wheel from lock to lock, slowly and smoothly. Do this for a couple of minutes. The heavy steering is caused by the low fluid level. Did you have this screeching problem before you removed the PAS pump? Also, although you have checked the belt condition, have you checked that it is tight enough? Screeching is usually indicative of a worn belt, end even though there aren't any cracks etc, the sides could be worn. V belts use their sides to drive the pulleys, so wear isnt always immeidately apparent. Are the sides of the belt all shiney? Whining is more indicative of a worn pump or rack, but usually pump.

	No i didnt have the screeching problem before i removed the pump it was a rattling sound but it was a rattling as soon as u start the engine and at idle but was very intermittent. - But now as mentioned it does not rattle or whine at idle but occurs when the car is revved above 1000rpm - The side of the belt is not shiny looks a bit rugged though but have checked that it is on ok and not rubbing anywhere also is it normal for the belt to get warm - And another thing which is baffling me is that the rattle has gone away if the pump was on its way out or was damaged would not the rattle jus continue on rather than shut up why would it stop when taken out and put back ? in cos i would take that the pump is whining cos of low steering fluid after reading various posts on other sites and googling this problem. -

	Get some oil into the pas system and let me know how you get on. Until you've topped up the fluid, there's not much point in discussing anything else as you might find all your problems cured by then. From my expereince, worn pumps tend to whine rather than clatter. The only time I have heard a pas pump clatter was when the mounting bolts had come loose. Insufficient fluid as well as air in the system can cause screeching but whether it is the belt or pump remains to be seen. Put some fluid in it and we'll take it from there.

	Well i gave up and hung up the bat sign and called ma dad who is way more experienced with cars and can almost fix anything anyway he had a look and says that it is the tensioner that has had it. The place that it goes in comes out as well as the spring i did notice that the belt was running a little wobbly but it has been working fine like this thus far. So i need a new tensioner and a new belt. The power steering is ok and has returned after filling it up any idea how much or where i can get one from. thanks.

	Hi Not to add to the confussion here, but quote from Skanders earlier post "I then checked the oil filter jus in case it was rattling around in their while doing that the oil went everywhere it went on the pulley wheels and the belt," Could that be causing the screaching sound? Has this all been cleaned up?

LuxAuto Members Profile Send Private Message Find Members Posts Add to Buddy List Senior Member II Joined: 10-April-2005 Status: Offline Points: 225	Posted: 16-August-2005 at 12:39
	No because the oil filter is actually compressed against the top , and from memoery has rubbers at the base and top, so there should be no opportunity for rattling. Rattling will only occur if a foreign object was present. Also, as the filter housing is full of oil, any noise would be suppressed by the oil. Even if rattling was to occur, I doubt it would be loud enough to turn heads. Oil on the pulleys,a although likely to cause slissping shouldn;t screech as the oil will be lubricating the two contact surfaces. Think he has sorted it anyway, the belt tensioner was worn.

	Yes it seems that way my dad says that one of the nuts on the tensioner was loose and thats what caused it to slip. anyway bmw want �75 for a new tensioner and �30 for a new belt way expensive but if its got to be done then i will. thanks hope i will have my car back in on the road as i miss the damn thing. jus 2 more ? would a loss of tension cause the rattling sound that i mentioned in the first place. And should the belt run completely straight on the pulleys without it wobbling or does it wobble just a little bit. cheers.

	No, loss of tension would not cause rattling, unless the tension loss was a result of the tensioner coming loose, in which case yes. The belt and pulleys should be perfectly straight. There might be a very slight wobble due to the runout on the pulleys but anymore than that and the belt is too loose. To determine the correct belt tension, a rough rule of thumb is to turn the belt (at it's longest run) through 90 degrees. If you can just about achieve this, it should be tight enough, anymore than this, then the belt is too loose.

	Yup when he got the tensioner out the spring had come out and it wouild not not go back in and stay in.
