It seems like something snapped in my steering, the belts squealed for a second and then I didn't have any power steering and my cars runs rough now

belts squeal for only 2 reason
it's bad. the belt.
or the accessorym it drives is Seized.

i guess you never head of a 5buck stethoscope
and listen to the accessory bearings, ah, alternator front and rear
i hear, front crying for help. easy as child play.
sold everywhere cars parts are sold.

there is no need to guess, , answer use tools.
this was true in 1920 and now, belts then and now all can squeal.
in the old days we had many belts and could drop them
then comes, SERP belts. one for all.
we dont have 1.3 swifts here, so cant see belt routing.

if this has an automatic belt tensioner on it this sounds like the tensioner is weak and needs replacing. a weak or bad tensioner does and can cause belt squealing and can throw the belt alignment off causing your problem.

Remove the belt and check those parts. Spin them by hand The alternator should spin freely. The PS pump will have more drag on it. Also check the tensioner and idler pulleys. When turning them Feel for roughness. All these should be smooth turning. No bumps or grinding. One of them is going to be tight or rough. The PS pump will move in and out a bit, this is normal.

Sounds like something with bad bearings. Check in the area of air conditioner compressor or power steering and yes water pump.even the belt tightener will do that.

Hi Genebaran, I doubt very much if the steering pump needs replacement, but the drive serpentine belt does. The squealing happens because the belt is slipping on the pump pulley when the pump is under load when the steering is turned to full lock. By the way, don't keep the steering wheel at full lock for longer than a few seconds at a time, as it will place the pump under too much load! Tell your mechanic to fit a new belt. Advise the mechanic to make a sketch of the routing of the belt before he removes the old one. Regards Johngee10

excess mechanical drag from the pump can cause the belt to slip and squeal, but before focusing on the pump I'd check the condition, tension and alignment of the belt. I might even try cleaning all the pulleys with an aerosol brake cleaner and install a new belt, particularly if the current one has more than 50,000 miles on it. It might be that the squeal is coming from or caused by a different belt-driven accessory.
A more typical noise from a power-steering pump is a high-pitched whine, not a squeal. Usually, if the steering wheel is stationary, meaning that the steering rack is not "asking" for assistance from the high-pressure fluid from the pump, there's little or no noise

Sounds like the belt, you're right on track. Check the belt(s) and replace if neccesary. If belts are fine, check for tightness. Should be about a 1/4" flexibility when you push down on them. If all is ok, belt dressing should take care of the problem.
Now, if for some reason, one of the components that run off the belts may be going bad, specifically a/c compressor. If it's starting to lock up, it will make your belt squeal and finally snap.

I think that you need new belts a quick check should cost you nothing at a reputable repair shop

The symptoms you describe are due to a slipping drive belt.

Slipping can be due to normal wear and tear and cured by retensioning the belt, or sometimes because something has contaminated the belt such as leaking power steering fluid or engine coolant.

It's quite common for incorrectly tensioned belts to squeal at start up as the belt takes up a shape when the engine's not running, and as it isn't tensioned correctly, takes a few seconds to start flexing properly again. As switching the A/C on also causes the squealing, it sounds like it's the belt that drives the A/C compressor that's slipping - it's not uncommon for there to be up to 3 belts, one for the alternator, one for the power steering pump, and one for the A/C, although it's more common for the alternator and power steering pump to be driven by the same belt.

I'm not familiar with your make and model so cant give any specifics as to how to re-tension your belts, but a tech manual will give you all the details.

Hi

The Power Steering Belt tension requires adjustment, to give it more tension, to cure the slipping, resulting in the squealing, or perhaps renewal, due to cracking or excessive wear.

Your Power steering Belt, belt is your primary problem.

Good Luck !
