Everything seems to spin freely except the one that goes straight into the engine. It is the biggest one. Is that one not suppose to? Also, how do you loosen the tensor? Thank you.

if you are talking about the one on the bottom that is the crank shaft and it better not spin freely ! The tensioner should have a square hole in it to fit a 3/8 drive ratchet, if not then take a wrench and put it on the bolt in the center of the pulley it will move the tensioner one way but not the other . pull the tensioner all the way up and then put the belt on the last pulley.............it is usually easiest to put the belt on all the pullies first except the alternator. put it around the tensioner befor you pull up on the tensioner . when you get enough slack put in on the alternator pulley and let the tensioner back down slowley. check and make sure it is on all of the pulleys right and all the way in the grooves.

I don't know what kind of car you have, but most of them have a bolt, or square hole in the tensioner bracket. Most require a special tool to loosen them. You can get an inexpensive one that will cover most autos for a little less then $20.00 at the discount auto parts stores. The lower pulley is the one on the engine that turns all the others, it isn't supposed to move. The belt is easy to replace, usually about 15 minutes or so. Make sure you know the way the old belt went around the pulleys before you start. There is usually a sticker with a picture showing the routing, but if there isn't, take one of your own (it'll save you alot of time). If your belt is still on the car, and just noisy, you can cut it off with a knife. Then use your installation tool, to ensure that the tensoiner moves freely ( not just the pulley spinning, but that the spring that keeps it tight is able to adjust freely). Then work your belt around the pulleys the same way that they were on, leaving the last pulley as the easiest to reach. Then while using one hand to keep the belts in place, use you other to operate the tensioner tool, and get the belt on the last pulley. When you are done remove all your tools from under the hood, and start the engine, giving the belt a few moments to seat itself, and check its operation (listen for unusual nioses, or squealing when revving the engine a little). This sounds like a big job, but it really isn't that hard, and it'll only take you a few minutes to do.

The 'biggest one' is the Crankshaft Pulley. It provides the power for the belt and spins the rest of the accessories on the engine.
Tensioners differ but all are spring loaded. Some have a socket to turn and others have a square drive (1/2") to pry with.
Getting a repair manual for your vehicle may help you.

No, the biggest pully isnt supposed to move, not that easily anyway, it is connected to your crankshaft. To move the tensioner there should be a square hole in the bracket that you can get a ratchet into and pull the tensioner to the side so you can slip your belt on it.

The big one is the crank and that will not turn by hand.
