Timing Belt Replacement 2.5T
 
T-belt replacement on a 05 LGT.
Ok here's a little how to on the timing belt replacement incase anyone is thinking about taking it on.
here we are at the start of the job. if there's anything i've missed or put that is incorrect please let me know.
( I am not responsible for anything that you do to your car)

here are the tools you will need.

here's the start of the job.

Next remove the "ram air scoop" and engine cover.

Now pinch off the upper Radiator hose, remove and take out your fans.

Now with the fans out of the way, you can take off the ACC drives.
Power steering and A/C belt with the tensioner bracket.

If you have the subaru harmonic balancer remover you can use it, if not
a chain wrench will work just fine. you'll have to really put the torque to this bolt. ( reinstall with a dab of oil on threads)

ok, now remove the timing belt covers. some bolts are hiding.
after covers are removed, put the harmonic balancer back on the crank so you can rotate the engine.

http://i525.photobucket.com/albums/c...t/103_0093.jpg

rotate the engine clockwise until the crank, and cam marks are at the 12-0-clock position.

here's the cam up at the 12o-clock positon.the upper cam lines up with marks on the plastic covers.
http://i525.photobucket.com/albums/c...t/103_0094.jpg

the upper cams line up with the cover, and the lower cams line up with the 6 o-clock marks of the upper cam. the 6 o-clock marks look like
II and the 12 o-clock marks of the lower cam are the same II marks.

now that it's lined up you can remove the tensioner and put in a vertical press. if you don't have one, use a pry bar and compress the auto tensioner. Taking more than 3 minutes to compress! after compressing install the "Grenade Pin" or a 2 mm (0.08 in) (nominal) dia. hex wrench
http://i525.photobucket.com/albums/c...t/103_0098.jpg

now you can remove the auto tensioner. tensioner removed you can remove belt.
http://i525.photobucket.com/albums/c...t/103_0102.jpg

while your here, my as well do the water pump.
when you install the new belt the arrows go to the right. start at the crank, (------ line is the start at the crank mark.) put the belt on from the crank pully twards the right, over the upper cam and down around the lower. (THESE ARE VERY HARD TO KEEP IN POSITION ROTATE UPPER-CLOCKWISE. LOWER COUNTER CLOCKWISE AND ONE AT A TIME!!) and here are the pics of the 3 and 6 o-clock timing positions. you need a mirror to verify the correct position of them
http://i525.photobucket.com/albums/c...t/103_0106.jpg

marks of the 3 o-clock position verify with mirror.

6 o-clock marks
http://i525.photobucket.com/albums/c...t/103_0109.jpg

after you've done this reinstall the auto tensioner, pull the "grenade pin" and push the tensioner down with your hand. ( it will auto tension :eek:)
fire it up, if it sounds normal then your ready to put it back together.
hope this helps anyone who has thought about doing this.

nice...thought it was much more difficult but that did not seem too bad :)

What does a dealership/.good mechanic charge for this?

Oh and WELCOME. Awesome first post by the way!

pyromarty 02-25-2009 11:34 PM

if i remember, dealer wants 4 hrs at 80pr hr plus 175 for the belt.
i do them for 150 labor you buy part. i can get belt for 125.
i don't recomend autozone belts. they are wrong by half a tooth.

:nono:

Don't use prybar on the tensioner if you want to reuse it!!! Subaru has very specific procedure about comporessing it extremely slowly and in particular position.

However, it's a good idea to replace the tensioner whenever belt is replaced.

Everyone please always check vacation pix before blindly following forum "how tos". :rtfm:

pyromarty 02-26-2009 12:01 AM

forgot about the compress slowly part. you can't press it closed in a horizontal position, only virticaly.

Do not use a lateral type vise.
Push the adjuster rod vertically.
Press-in the push adjuster rod gradually taking
more than three minutes.
Do not allow press pressure to exceed 9,807
N (1,000 kgf, 2,205 lb).
Press the adjuster rod as far as the end surface
of the cylinder. Do not press the adjuster
rod into cylinder. Doing so may damage the cylinder.
Do not release the press pressure until stopper
pin is completely inserted.

as from the book. most people won't have a vertical hydraulic press. so just compress in 3 or more minutes.

last time i checked...vacation pix didnt work anymore

The factory manual does not specify a certain mileage of when to replace the timing belt. It only states to check it at certain mileages.

So do we only replace it if it looks worn out, or what is the accepted mileage for changing it out (on the 2.5 turbo)?

Bump, I was just going to replace it at my next 30K Interval.. which is 90K.

At 105000 miles service, they say to replace it. check out link,

Thx guys for putting this up. Just did mines today. Only thing to add is make sure you get a long enough chain wrench and use a vise grip between the sprockets to keep the cams in place before and after timing belt removal. I could have saved 2 hours...:mad:

Ridgeracer 09-14-2009 06:57 PM

BTW....after 106K miles the belt looked fine. My only concern was the water pump. The area around it was a little damp with antifreeze before removal.
