Find the lock nut that holds the long adjustment bolt in place and use your wrench to loosen it. Turn the adjustment bolt. Slip off the old belt and install the new one, once the belt tension is
released. Make sure the belt is correctly seated on all pulleys. Turn the adjustment bolt the other way to bring the component away from
the engine and add belt tension. Test the belt for correct tension by
pressing on it and checking deflection. Tighten the adjustment lock bolt and the pivot bolt, when the belt has the right tension. Here you can find the quality parts http://www.1airconditioning.com/mitsubishi_ac_compressor.htm
Hi, you have to remove the power steering pump to get the alternator out. Please let me know if you have questions, and thanks for using FixYa.

7. Tighten the lock bolt.
8. Install the new alternator belt
9. Rotate the adjuster bolt clockwise until the belt is tight like it was before you removed it.
Loosen the alternator mounting bolt.
NOTE: Do not pry against the stator frame. Position the prybar against a stronger point, such as the area around a case bolt.
Fig. 1: A belt tension gauge should be placed on the longest span of the belt to check tension — 1.8L engine
Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
Adjust the tension to 86–103 lbs. (383–461 N) for a new belt or 68–86 lbs. (304–383 kg) for a used belt.
If a belt tension gauge is not available, adjust the tension to 0.31–0.35 in. (8–9mm) deflection for a new belt or 0.35–0.39 in. (9–10mm) deflection for a used belt.
Tighten the alternator adjusting bolt to 14–19 ft. lbs. (19–25 Nm).
Tighten the alternator mounting bolt to 27–38 ft. lbs. (37–52 Nm).
Lower the vehicle.

1.9L Engines
The accessory drive belt for 1.9L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
Fig. 5: Drive belt routing — 1.9L engines
2.0L Engines
The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced.

REMOVAL & INSTALLATION of timing belt:
Fig. 1: View of the timing belt cover
Fig. 2: Loosen then timing belt tensioner using a ratchet and short socket
Fig. 3: Matchmark the direction of rotation of the timing belt
Fig. 4: Once loose, pull the belt off the camshaft pulley
Disconnect the negative battery cable.
Turn the crankshaft to align the timing belt matchmarks and set cylinder No. 1 to Top Dead Center (TDC) on the compression stroke. Once in this position, the engine must NOT be turned or disturbed.
Remove all necessary components to gain access to the cylinder head and timing belt covers.
Remove the cylinder head and timing belt covers.
There are 2 belts in this system; the one running to the camshaft pulley is the timing belt. The other, shorter one drives the balance shafts and is referred to as the balancer belt or timing balancer belt. Lock the timing belt adjuster in position by installing one of the lower timing belt cover bolts to the adjuster arm.
Loosen the timing belt and balancer shafts tensioner adjuster nut, but do not loosen the nut more than 1 turn. Push the tensioner for the balancer belt away from the belt to relieve the tension. Hold the tensioner and tighten the adjusting nut to hold the tensioner in place.
Carefully remove the balancer belt. Do not crimp or bend the belt; protect it from contact with oil or coolant. Slide the belt off the pulleys.
Remove the balancer belt drive sprocket from the crankshaft.
Loosen the lockbolt installed to the timing belt adjuster and loosen the adjusting nut. Push the timing belt adjuster to remove the tension on the timing belt, then tighten the adjuster nut.
Remove the timing belt. Do not crimp or bend the belt; protect it from contact with oil or coolant. Slide the belt off the pulleys.
If defective, remove the belt tensioners by performing the following:
Remove the springs from the balancer belt and the timing belt tensioners.
Remove the adjusting nut.
Remove the bolt from the balancer belt adjuster lever, then remove the lever and the tensioner pulley.
Remove the lockbolt from the timing belt tensioner lever, then remove the tensioner pulley and lever from the engine.
This is an excellent time to check or replace the water pump. Even if the timing belt is only being replaced as part of a good maintenance schedule, consider replacing the pump at the same time.
To install:
If the water pump is to be replaced, install a new O-ring and make certain it is properly seated. Install the water pump and retaining bolts. Tighten the mounting bolts to 106 inch lbs. (12 Nm).
If the tensioners were removed, perform the following to install them:
Install the timing belt tensioner lever and tensioner pulley.
NOTE: The tensioner lever must be properly positioned on its pivot pin located on the oil pump. Be sure that the timing belt lever and tensioner moves freely and does not bind.
Install the lockbolt to the timing belt tensioner, do not tighten the lockbolt at this time.
Install the balancer belt pulley and adjuster lever.
Install the adjusting nut and the bolt to the balancer belt adjuster lever. Do not tighten the adjuster nut or bolt at this time.
NOTE: Be sure that the balancer lever and tensioner moves freely and does not bind.
Install the springs to the tensioners.
Move the timing belt tensioner its full deflection and tighten the lockbolt.
Move the balancer its full deflection and tighten the adjusting nut.
The crankshaft timing pointer must be perfectly aligned with the white mark on the flywheel or flex-plate; the camshaft pulley must be aligned so that the word UP is at the top of the pulley and the marks on the edge of the pulley are aligned with the surfaces of the head.
Install the timing belt over the pulleys and tensioners.
Loosen the bolt used to lock the timing belt tensioner. Loosen, then tighten the timing belt adjusting nut.
Turn the crankshaft counterclockwise until the cam pulley has moved 3 teeth; this creates tension on the timing belt. Loosen, then tighten the adjusting nut and tighten it to 33 ft. lbs. (45 Nm). Tighten the bolt used to lock the timing belt tensioner.
Realign the timing belt marks, then install the balancer belt drive sprocket on the crankshaft.
Align the front balancer pulley; the face of the front timing balancer pulley has a mark, which must be aligned with the notch on the oil pump body. This pulley is the one at 10 o'clock to the crank pulley when viewed from the pulley end.
Align the rear timing balancer pulley (2 o'clock from the crank pulley) using a 6 x 100mm bolt or rod. Mark the bolt or rod at a point 2.9 in. (74mm) from the end. Remove the bolt from the maintenance hole on the side of the block; insert the bolt or rod into the hole. Align the 2.9 in. (74mm) mark with the face of the hole. This pin will hold the shaft in place during installation.
Install the balancer belt. Once the belts are in place, be sure that all the engine alignment marks are still correct. If not, remove the belts, realign the engine and reinstall the belts. Once the belts are properly installed, slowly loosen the adjusting nut, allowing the tensioner to move against the belt. Remove the pin from the maintenance hole and reinstall the bolt and washer.
Turn the crankshaft 1 full turn, then tighten the adjuster nut to 33 ft. lbs. (45 Nm). Remove the bolt used to lock the timing belt tensioner.
Install the lower cover, ensuring the rubber seals are in place. Install a new seal around the adjusting nut, DO NOT loosen the adjusting nut.
Install the key on the crankshaft and install the crankshaft pulley. Apply oil to the bolt threads and tighten it to 181 ft. lbs. (250 Nm).
Install the upper timing belt cover and all applicable components. When installing the side engine mount, tighten the bolt and nut attaching the mount to the engine to 40 ft. lbs. (55 Nm) and the through-bolt and nut to 47 ft. lbs. (65 Nm).
Connect the negative battery cable.

My sincere apologies for the severly delayed response. I am personally going back to answer your unanswered questions.
I do not know if you still need this information, however I am answering it in case you still do.
Click on the following direct Link. It has several Diagrams for your Belt depending on your engine size and options (AC/No AC etc.). These also point out where the Locking and Adjusting Bolts/Nuts are, to loosen the belt and remove; and reinstall the Belt and TIGHTENING.
Again my apologies... Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!
MORE INFORMATION NEEDED. There are several deices to adjust belts. On serpentine belts there is a tensioner pulley that should hold spring applied pressure on the belt. If that doesn't work it needs to be replaced. On some engines it is tightened by adjusting an idler pulley. On some it is accomplished by adjusting the alternator or power steering pump. Look to see which part has an adjustment and loosen the nut or bolt holding it, move the part to the desired tension and tighten the nut or bolt.
