Default Timing belt and Power steering belt?

Are timing belt and power steering belt two seperate belts??

My primary purpose of asking this question is because my power steering seems to almost lock up or stop working when i'm reversing out of the parking space and turning at idle.
Furthermore, my car makes that squealing noise during start up in the morning AND while driving.
Seems like this problem is getting worse as times goes by and wanna fix real soon.

So I did a bit of search and figured it could be my pulley and/or timing belt.
I already have bought crank pulley and timing belt.
Would replacing these two peices fix this particular problem?
Thanks in advance.

Timing belt and alternator/power steering belts are two different items

I would do the alternator belt first and check the tensioner. Not sure why you bought a crank pulley...

No.

The timing belt is a toothed belt that synchronizes the camshafts to the crankshaft. It's behind the black plastic cover that looks like a dogbone on the front of your engine. You should replace the timing belt at the factory reccomended interval (which is something like 115,000 miles). This is not something to be done by a novice.

The power steering / alternator belt, like the A/C belt is one of the ribbed belts that is exposed in front of the timing belt cover. These are also known as accessory belts.

It is your power steering / alternator belt that needs replacement. While you're in there, replace the A/C belt as well. You will need a metric socket set and an extension to replace the belts. These are very easy to do, good for a novice mechanic. Just make sure not to tighten the new belts too much. If they still squeak, just tighten them a little more. If they still squeak on a cold start (usually after a dew has settled), tighten a little more. Over-tightening can damage the bearings that the idler pulleys (the ones used for adjustment) turn on.

Replacing the crank pulley will require you to lock the engine in place and using a breaker bar and a large socket. It's not hard, but it's also not something for a total novice. You may want to ask for help in your local forum. If there's someone nearby willing to drop by to lend you a hand or at least some advice, you'll be well on your way. Beer/Pizza/etc are always good things to offer in return.

Good luck.

thank you guru's!!
Awsome details Beaverboy! thanks to you both.
I do not deny the fact that I am a novice and I guess it was my hasty move on buying the timing belt. But still it was recommended by the dealership when I went there for free check-up.

Any advice on where I could purchase the power steering/ alternator belt from?
And do you guys maybe have a link to power steering/ alternator belt replacement instruction?

Try subarugenuineparts.com for your belts.
As far as breaking your CP loose, I have never used a breaking method. I made a special long shaft ratchet adapter and I hit the shaft with a mallet and it breaks loose perfect. No sense in hurting yourself trying some of the crazy techniques I have seen posted.
When installing your new CP ensure you have it aligned perfectly on the keyway on the crank shaft, if you are a little off and force it on you will just throw the AL CP in the trash. Hopefully the one you got is just lightened and not UD.
Did you check your PS fluid?

ohhhkay.... so many abbs. lol
I assume that by CP you mean crank pulley? if so, yes I do have Perrin lightend one... which by the way doesn't feel as I light as I imagined it to be. I guess the stock one must be REAL heavy! haha
but what's AL CP and PS fluid?

You should know that if you replace the crank pulley (or any other pulley) with an underdriven setup, you will likely need different size power steering and alternator belts. The manufacturer should be able to provide the proper size belt.

Which is just one of the reasons you should get a light-weight pulley, not an under-driven one.

Here's the link to the ALT/PS belt; https://www.subarugenuineparts.com/oe_parts_cat.html

1) go to their site by the link
2) type in vehicle year and make
3) under "Collission Parts"
4) Fill in year, model and make
5) type in "Belt" under "Keyword"
5) enter the 1st part listed will be Alternator belt $17.94

If you PM subiegal (Jamie) here she will help you out. Also you can call her at Chaplins Subaru from the site. You were probably just looking for the PS belt, it is not a single unit belt.
SGP's has probably one of the best shipping times and customer service, so much so I use them and they are 3000 miles away, my Subaru dealer sucks.

AL=Aluminum
CP= Crank Pulley
PS=Power Steering
Fluid=Fluid

Timing belt is the one driving the camshafts, you can't see it physically. It's located at the front of the cylinder head covered by a black case.

Power steering belt is visible from the engine bay, it's located at the right side (passenger side) where you can see the belt are driven by the crank pulley.

You can probably get the two belts cheaper at Napa/Autozone/Checker.

I work at Napa, so I can provide those part numbers for ya...

A/C - NBH 25-040353

P/S & Alt - NBH 25-050350

Those numbers can probably be crossed at any parts store, too

ok, had to bump this thread back up because I just could not find an instruction on how to replace PS belt and AC belt.
Searched at scoobymods.com as well but nothing.

Anyone have an instruction?

In case you missed his question, it's a good one.
