Default How to check for broken timing belt ?

I have a '97 Legacy GT that cranks but won't start. It really does not sound much different than the usual starting sound in my opinion. The CEL codes were misfires + camshaft + crankshaft sensors. I replaced both sensors and still it won't start. Returns a camshaft CEL.

Local tech says it could be a broken belt and I should check it. The belt was replaced at 156k and the car has 220k. Tech says even so, something else could have seized and snapped the belt. Lovely. There's 3 bolts he says. Would I remove the 3 bolts from the driver's side cover ? And, does the cover just pop off ? Pics would rock.

How will I know if the belt is broken, should it be obvious even from one side ?

The cover is easy to get to. there is a bolt on the top, and 2 on the bottom. my RS is lowered a little, but I as still able to get under there and loosen the bolts. wish I had a pic, but you should be able to figure it out when you look at it. I know because I just checked mine, I am having the same problem. Mine isn't broken, but it might have jumped a tooth. That I can't tell from looking in the cover.

I took it off this evening. I had to remove the coolant resevoir to get at the bolt on the bottom. It wasn't that tough when you get down and do it. The belt was slightly loose and from what I was told it should be snug. The car is now on a flatbed to see if something else snapped and what the damage is. Wish me luck !

What does it mean when the belt jumps a tooth ?

The belt jumps a tooth when it gets enough slack in it to stay in the same place on one pulley, but move over on another. Say the crank is at TDC, and so is one camshaft, but the other is x degrees off. It might be your tensioner.
