How do you replace a 2000 Mitisbuishi Mirage Alternator Belt. Do you have to remove the other belt if so how do you get them off

Bad alternator bearing is one possibility. Remove belt and spin everything it drives to find binding part. Other possible is poor alignment of driven parts.

ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

ALTERNATOR AND A/C COMPRESSOR

1. Disconnect the negative battery cable.

CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

1. Raise and safely support the vehicle and remove the front undercover.
2. Loosen the tension pulley fixing nut and relieve the tension on the belt by turning the adjusting bolt.
3. Remove the belt.

To install:

1. Install the belt on the crankshaft and alternator pulleys.
2. Using the adjusting bolt on the tensioner, tighten the belt to the desired tension.
3. Tighten the fixing nut to hold the adjustment.
4. Install the undercover and lower the vehicle to the floor.
5. Connect the negative battery cable.

POWER STEERING BELT

1. Disconnect the negative battery cable.

CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

1. Raise and safely support the vehicle and remove the undercover.
2. Remove the alternator and A/C compressor belt.
3. Lower the vehicle and remove the cruise control pump link assembly.
4. Place the power steering hose under the oil reservoir.
5. Loosen the tension pulley fixing bolts and remove the power steering pump drive belt.

To install:

1. Install the power steering pump drive belt.
2. Insert an extension bar or equivalent into the opening at the end of the tension pulley bracket and pivot the pulley to apply tension to the belt.
3. Tighten the fixing bolts.
4. Raise the vehicle and install the alternator and A/C compressor belt.
5. Install the undercover and lower the vehicle.
6. Connect the negative battery cable.

3.0L SOHC Diamante

1. Disconnect the negative battery cable.
2. Loosen the lockbolt on the face of the A/C tensioner pulley.
3. Turn the adjusting bolt of the A/C tensioner pulley to loosen the tension of the A/C belt.
4. Remove the A/C compressor belt.
5. Loosen the locknut on the face of the power steering/alternator tensioner pulley.
6. Turn the adjusting bolt of the tensioner pulley to loosen the tension of the belt.
7. Remove the power steering/alternator belt.

To install:

1. Install the power steering/alternator belt first and then the A/C compressor drive belt.
2. Adjust the belts to the proper tension by turning the adjusting bolts and tighten pulley fixing nut/bolt.
3. Tighten the mounting nut of the power steering/alternator tensioner pulley to 36 ft. lbs. (50 Nm).

I would replace the steering pump belt at the same time you do the alternator belt (buy both).
To take off the alternator belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp(or a block fuse under the hood). Facing the back of the car , reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change the belt.
To take off the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the pulley it holds the adjuster pulley in place . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley to adjust/take off the steering pump belt.

First, feel the tightness of your belts. You will have to tighten the new belts to the proper tightness. If they are too tight, they will wear the bearings prematurely. If they are too loose, they will slip.

Alternator Belt Removal

1. Loosen the alternator lock nut.
2. Loosen the adjuster bolt.
3. Rotate the adjuster bolt counter clockwise to release the tension on the belt.
4. Remove the belt.
   

Similarly for the compressor belt

1. Loosen the lock nut.
   
2. Loosen the adjuster bolt.
3. Rotate the adjuster bolt counter clockwise to release the tension on the belt.
4. Remove the belt.

5. Install the new compressor belt

6. Rotate the adjuster bolt clockwise until the belt is tight like it was before you removed it.

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.

10. Tighten the lock bolt.

Can not be done, the belt or belt's have to be remove, to install alternator belt, no short cut's for this job.

ALTERNATOR DRIVE BELT SLIPPING BELT TENSION NEED ADJUSTING OR DRIVE BELT WORN GLAZED.CHECK ALTERNATOR BATTERY FEED WIRE AND FIELD WIRE FOR LOOSENESS AND DAMAGE.OR THE THE VOLTAGE REGULATOR COULD BE FAULTY.

( BEFORE ADJUSTING THE ALTERNATOR BELT DISCONNECT THE NEGATIVE BATTERY CABLE OR YOU MIGHT BLOW AN EXPENSIVE HIDDEN FUSE)to change the alternator belt, you have to loosen the lower mount bolt on the alternator, loosen block shaped bolt that the long adjuster bolt goes through, and loosen the belt by turning the long adjuster bolt, take off the belt. to adjust the power steering belt, there is a long adjuster bolt that moves a tensioner pulley, first you have to loosen the nut that holds the pulley in place , now the pulley can be moved with the adjuster bolt.

If you have limited / no mechanical knowledge leave this to an Auto Technician.

This a relatively easy job.

Undo the alterantor lock nut (12mm ring spanner / socket wrench)
Undo the alternator adjustment bolt almost fully (Either 10mm / 12mm wrench)

Get under the car and loosen the main alterantor bolt using a 14mm wrench. Just loosen enough to move alternator, it is not to be removed.

Pull alterantor forward to slacken belt / remove belt.

Replacement is the opp of the above.

Ensure the MAX. deflection at the middle of the belt is only 12mm (1/2") after all redfitting is done.

Failure to have it this tight will wear it out very quickly!!

UNDO THE BOLT PUSH THE ALERNATOR TOWARDS THE ENGINE REPLACE THE BELT USE A BAR AGAINST THE ENGINE AND ALTERNATOR PULL IT JUST TIGHT AND DO UP THE BOLT
