Yesterday my alternator belt snapped on my way to work. I knew what it was right away - it was pretty loud, and I lost all heat in the car. I still managed to drive about 8 kilometres to work, but it was a little nervous! I turned off everything electrical in the car (heated seats, fan, headlights) and drove really slowly. Luckily it was quite cold outside, so I didn't overheat the engine - it did get up to 4 blobs, though. Amazing, huh? Doesn't overheat even though the water pump is not pumping coolant. The battery light came on, but I wasn't worried about that - I knew that was simply because the alternator was no longer functional. Anyhow... I got to my work where fortunately we have a shop, so I parked inside and went on my merry way. I came back the next day with my spare belt and some tools, and set down to change the belt.This is not really a roadside repair, unless you are really in the middle of nowhere. The car is still driveable for a short distance with the belt shredded, but you probably don't want to go too far. Enough to find a safe place to pull over.Here is the procedure:1) Jack up the car and take off off the passenger-side rear wheel. Prop the car up as high as possible, because you are going to be on your back most of the time.2) Take out the inner fender cover. There are 3 plastic nuts that hold it in - be careful not to strip them. I believe a 9mm socket will do the trick. It is a bit of a bear to get out - you have to wiggle it around a fair bit, but it will eventually come out.3) You have to now take off the alternator cover. This is a square-ish piece of plastic that is attached to the frame in two locations. There is a plastic cap that you pry off with a flathead screwdriver, it just pops out, and then you can pull the cover right out of the frame.4) Now you are looking at the crankshaft pulley right in front of you, and the alternator. The way to get the belt off (or put a new one on - mine was already off) is to slacken off the alternator. There is a nut at the bottom, and one at the top. Use a 15mm wrench to loosen or take off the bottom nut, and then use a 16mm wrench to loosen the top bolt. There are only 2 nuts altogether, so you really can't go wrong here. Don't take out the top bolt - just loosen it so that the alternator will move. With both of these loosened, you can now move the alternator a little bit towards the back of the car. not much, but just enough to get the new belt on.5) Fit your new belt over the tensioner at the top first - it is a real bear to get at - you can't really see it, you can only go by feel. Fit it over the tensioner, then around the alternator, and then get it started on the crankshaft pulley. You can use a 14mm wrench to turn the crankshaft, thereby pulling the belt onto the pulley. I tried for the longest time to get the belt on without turning this pulley, but it is all but impossible, even with the alternator moved over as far as it can go. It is so much easier just to turn the crankshaft pulley and pull on the belt, just as if you are putting a new chain on a bicycle sprocket.6) With the belt on and around the 3 pulleys (crankshaft, tensioner, and alternator) make sure that it is sitting in its groove properly. The tensioner doesn't have the same grooves as the other 2, but it you'll see where the belt fits once you run your finger over it.7) With a screwdriver or something long and flat-ish, move the alternator back to the same position on the bracket where it was before you moved it over. Again, you'll be able to see where this is because the nut has made a good indentation on the bracket. If you fit it exactly in the same spot, then tighten the nut up with the 15mm wrench, you'll see that the belt is really just right. Not too tight, not too loose. Then reach up with your 16mm wrench and tighten up the top bolt on the alternator. Make sure they are good and tight, as tight as you can manage. You don't want anything coming loose down the road!8) You should probably start the car up and let it run for a bit at this point. Just to make sure that everything is working fine. I let mine run for a couple of minutes, and then checked the tension in the belt again. Everything was fine.9) Snap the alternator cover back into place on the frame, and then put the inner fender cover back in. Put your wheel back on.10) Wash your filthy hands and give yourself a good pat on the back.By the way - mine gave out at about 135,000 kilometres.Hope this helps!Ross
