With the string from the movable pulley
Put on a new pulley bearing.
Fixed joint. When you are born, there are gaps in your skull, then they start to get put together and it becomes a fixed joint.
On the fan pulley...
Remove belt. Remove the bolt and then pull the pulley off. Put new pulley in position. Put the belt back on.
Take it to a jewlers to check it out but it should be able to get fixed! :)
On the belt routing diagram under the hood (near the grille, but under the hood) you will find the location of the 'tensioner' pulley. You need to get a 15mm socket and place it on the bolt on the tensioner pulley. Then use a ratchet to put clockwise pressure on the bolt to loosen the tension on the belt. This will allow you to remove the belt from the idler pulley, remove the bolt, put on the new pulley. Now put clockwise pressure on the tensioner pulley again to put slack in the belt so you can slip it around the new idler pulley. You're done.
How do you put the pulley back on the power steering pump on a 1990 suburban
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
You will need to loosen the tensioner pulley. Put the alternator belt on. Push the tensioner pulley to the left until the alternator belt is tight. Tighten down the tensioner pulley.
To put a string through a double pulley, first thread the string through one side of the pulley. Then, loop the string around the groove of the pulley and thread it through the other side. Make sure the string is running smoothly through both sides of the pulley before using it.
Pry up on the tensioner pulley.
