my sister -in- law , 98 forester 185,000mi a/t, , belt came off , no power steering , battery light on, did a search , seems it could be a worn crank pully key -way, what size of wrench does it take to loosen bolt, ? i have not seen the car yet , going shortly to take a look at it, the pully wobbles , , i have 2 crank pullies here to take along , but no key-way, which surely autozone or napa has ? thanks
same size as a large deep well spark plug socket, 5/8s i think. take a breaker bar with you.
EDIT: it's 22mm or 7/8 not 5/8.
there are several good threads on the subject, do a search. (one this week in fact)
if the timing jumped, there could be bent valves.

Be sure the key is pointed down when you remove the belt. I remove the cogged idler on the water pump. Then you can turn the shortblock over if you need to get the key back up on top and put the gear on. Then rotate back to the down position and put the timing belt back on.
If the tip of the key got torn its possible the end of the crank snout got damaged as well. Verify this isn't the case before proceeding. If it is call me, I can try to get you a kit to fix the crank and key from a local shop here in Denver that makes them.
You are going to have to compress the the tensioner. If its got a blue bearing and pivots(which is stock for this year), then you need to do so in a press, SLOWLY, over a 10 minute period put light pressure on. You can press it while its on the engine as well with a prybar but again, super slowly take over a minute to do its motion in this case. Finesse and patience required. Lots of people have done it too fast and pushed the oil past the seal. Later on this can cause the timing to jump, bend valves, etc. If in doubt put a new tensioner on.
DO NOT compress this tensioner in a vise.

There is a small hole that goes through the tensioner. Find an allen key or nail that will go completely through it.
Once compressed put the tool in and do not remove until after the belt is reinstalled properly.
