Re: fto fitting alternator belt
Loosen these 2 bolts in this order
once the 1st one is loose, loosen the 2nd one until the belt is loose enough to remove the belt(if its still on). then spin the alternator pulley by hand to see if it is seized up. its a good idea to check the tensioner pulley too.

if you look at the engine youll see the alternator directly above the alternator you will see a pully which doesnt have grooves on the surface like the rest of the pullys. this smooth pully is the tensioner pully and you will need to use a large ratchet or spanner to to lift up the pully (its on a spring) so you can fit the belt.
shiney pullys indicate that they sit or rest on the outside of the belt.
Spray some WD-40 on the pully where the belt rests on the pully while the engine is running and the noise will go away, also make sure the belt is tight enough around the pully, if it is loose then tighten it
Look for the belt tensioner pully. If you don't know what this is run the engine and look at the pullies.The one you want is the only one that will be moving up and down.This is the one that is spring loaded.Think it is drivers side top.It may have a square hole in the arm to put a ratchet in.Thinking 3/8" drive but may be 1/2" ,if there is not a hole then you will need a socket that fits on the center bolt of the pully.I will suggest a long handled ratchet or breaker bar,if you don't have one you can put a pipe over the handle of a short handle."cheater pipe"Put force on it so the pully comes up off the belt.If you don't have a belt routing sticker still on your radiator shroud draw one before you remove it.I think the belt comes off on the drivers side.when putting on the new one start at the crank pully,around the waterpump,then to all pullys on passinger side.The last one will be the alternator.Hold the belt down in front of the tensioner pully attach the ratchet and pull until you can slip the belt under the pully,Make sure the belt is properly seated in all pullys before starting.Helps if you have a spare set of hands.
It certainly will. It will show the O2 sensor activity, coolant temperature, relative throttle position, manifold absolute pressure, short term and long term fuel trims, and a whole host of other mind bending sensory values and attributes, which the operator will then be able to decypher and pin point where the problem is.
