    you need the belt, and the tensioner which are avail at minnetonka morries for a pretty good deal with mnsubaru discount.

    also a good idea to replace the water pump and thermostat while youre in there because you need to remove the timing belt to replace the pump anyways.

    check all pulleys for play and that should do it.

    my list, and where I like to get the parts (OEM is nice....but for the most part, unnecessarily expensive, even with the discount).


    belts, pulleys and tensioner. I would check and only replace the pulleys as needed if it's the cars first tbelt change, after that, I would replace them all, regardless. There are PCi (preferred components, inc.) kits available on ebay (like this one) for a good price. I've run these kits on many of my cars with wonderful results. definitely OEM quality for much less.

    water pump. Beck/Arnley brand from RockAuto.com (again, I use this brand for numerous parts, clutch, water pump, brake calipers, etc.....OEM quality for less, NOT remanufactured!!)

    Thermostat and gasket. just go OEM. don't skimp here, they really don't cost enough to justify cutting the corner. OEM ones are available from RockAuto.com as well. and last time I checked it was less than the morries discounted price....

    the 90* hose from the water pump to the heater line. again, if this is the first time you've been in there, just check it, after that, replace it no matter what. Just pull off the old one and take it to a parts store, they will probably have something that will fit just fine in stock. also get a pair of real live hose clamps for it.

    Crank and Cam seals. this is like $20 in parts, and $300 in labor to do separately. do them now. awesome quality Viton seals available from Smallcar.com for a great price.


    If you've got the engine out (not necessary.....but maybe you're doing clutch too....I dunno). rear main seal, again Viton from smallcar. also replace the seals for the access holes. same deal, cheap to buy, big project to replace. OEM from your local dealer is the way to go here. ditto on valve cover gaskets/grommets.

    ^^ That is perfect. Tons of info.....many people say you dont need to do camseals and such, but if your in there already, you might aswell replace them.

    IIRC (I'm going strictly off of memory here) w/ mnsubaru discounted price.
    Tensioner - $80
    TBelt - SOHC $85 DOHC $115
    Waterpump w/ gasket- $80-100
    Thermostat - not sure, I think between $15-30
    Also need engine coolant....

    I think those prices are good for a ballpark figure, but one of them boys at the dealership should check my memory, LOL cause I know its not too good.

    The waterpump gasket is leaking in my Outback. I'll gladly take pictures and do a step-by-step write up on changing a timing belt. Its very easy to do, however, any mistake could ruin your engine......making it alittle intimidating. Anybody with good directions should be able to figure it out.

    I'm going to do my Timing Belt this weekend. I've got a 2000 Outback, and I'm looking for OEM or better parts.

    I'm wondering why I wouldn't go with Billstien T-belt Tensioner from Car Quest for $50 less than Dealer.

    I can also save 25 on the belt itself from Car quest. (MBL - OEM)

    The Water Pump would be 69 rather than 133.33.

    Idlers and pulleys each have a 10 to 20 dollar difference.

    Thermostat is 14 rather than 27.

    I guess I have two over all questions.

    What parts do people recommend spending the extra cash for "Genuine Subaru"?

    Also, any specific recommendations for parts? Or suggestions?

    This is something I need to look into... I have a 113k on this Forester, nothing looks old, and nothing looks new in this region... so I'm on the fence. No records came with it.

    you could remove a side of the tbelt cover (has 3 segments), really just 3 bolts i think, and check out the belt for condition

    while you are in there, I would recommend pulling off the oil pump and replacing the O-ring behind it. Otherwise we use the Continental timing belt kit from World Pac. comes with all new idlers and belt

    Ok, all questions are for an 03 wrx with 101k miles.

    Cam seals. Should I plan on changing them as preventative maintenance? Or only if they show signs of leaking? I didn't change them on my wife's car and now 40k later one of them is leaking pretty bad and I have to take it apart again, but that's a '99 and has the old black color seals. I heard the newer brown ones last longer?

    Cam gears. If I replace the cam seals, I read somewhere the three plastic cam gears are not reusable, once they come off you need to replace them? Is that true? Also, I've heard they're a real pita to get off, any tips? Do I need a special tool or can I just break them loose before I take the belt off?

    Reassembly. Is it easy for one person to align everything and reassemble the belt without damaging the valves? I know the ej22 SOHC engines were very simple to put back together, but I'm a little paranoid with the DOHC and damaging the valves.

    the cam gears are pretty tough to break loose. if you try it with the belt on there's a good chance you are just going to jump teeth. I used the old belt and basically made a belt wrench and had my dad hold it while I broke the bolts free (it was really hard to hold them). However, that's on an STI with avcs stuff - I think the wrx's have a flat spot on the cams (under the valve cover) that you can put a wrench on to hold them while you take the gear off.

    re-installing the timing belt was pretty tough - I don't think I could do one by myself the first time (we did it 3x's on my engine and even after that I wouldn't do one by myself).

    Yeah after I read the instructions for installing the belt I was pretty scared. But after reading in between the lines it was really really easy. The belt has premarked lines on it that line up with all of the marks on the cams and the crank gear.

    The hardest part of getting my engine apart was getting the cam gears off like Carl said. luckily I had the valve covers off and was able to put a box end wrench on the flat spots of the camshaft.

    I just finished up doing my own timing belt. WOW it was way easier then I thought. It helped that I had a factory service manual. With the manual it took me all of 5 minutes to get the cams set and the belt on. Won't hesitate to do this again. I've already told a couple co-workers that I'd do there's when the time comes.

    I've done head gaskets on 13 Subaru's in the last 2 years (kinda a side thing), both 2.2L and 2.5L SOHC and DOHC. Have some home-made crank and cam tools if anyone ever needs to borrow them, no charge. I'd even be willing to help a fellow sube owner out if you want, or give you my 2 cents in what I've learned. Ask anytime.

    Just a few pro tips i learned after doing my first timing belt.

    Lay a breaker-bar on the frame and bump the starter to loosen the crankshaft bolt.

    I also went to the auto parts store to rent a cam holder... Didn't work due to the lip on cam. But an easy solution is to use a vise grips to hold the two cams together. The vise grips don't need to be in Hulk mode. Just tight enough to make them lock.

    Before using the vise grips we tried to do it at least 15 times and every time ZING went the cam gear. Needless to say we worked well into the night the first time.

    Went into doing my buddies belt knowing these tips and we got it done in a couple of hours.
