did the belt fall off, not told , the story.

all have tensioner that must be retracked
2 kinds, fixed bolt kind
or, the spring loaded kind and to be frank we make sure is kind is not bad first. if there at 19 years old.
called the main front drive belt system. (not cams)
I am not answering for all 7 sorry.
all we do is look at it. see what tensioner is there,
if spring type we retract it with a beaker bar socket drive. per the manual told in services manuals
if not spring type out comes my tension tool and per spec, do that.

Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.

2 Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.

3 Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.

4 Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.

5 Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.

6 Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.

7 Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.

1. Insert a 1/2 inch flex handle in the square hole in the tensioner. The tensioner has a square hole cast into the rear of the tensioner body directly behind the pulley. Rotate the tensioner clockwise and remove the belt from the pulleys.
   

NOTE As an alternate method, a 16mm socket can be placed on the tensioner pulley bolt and rotated clockwise to remove the belt.

To install:

1. Following the schematic on the decal under the hood, loop the drive belt over all the pulleys except the alternator pulley.
   
2. With the belt installed properly on all except the alternator pulley, rotate the tensioner as described above and install the belt on the alternator pulley. Ensure that all the V-grooves make proper contact with the pulleys.
   

4.6L Engine
WARNING Do not allow the drive belt tensioner to snap back as damage to the drive belt tensioner or personal injury could result.

1. Rotate the drive belt tensioner clockwise with a breaker bar installed in the 3/8 inch square hole in the drive belt tensioner.
   
2. Lift the drive belt over the idler pulley flange and remove the drive belt.
   

To install:

1. Following the schematic on the decal under the hood, position the belt over the pulleys, except the idler pulley.
   
2. Rotate the tensioner as described above and install the belt on the idler. Ensure that all the V-grooves make proper contact with the pulleys.

I hope helps with this. Good luck.

this should be the correct routing for that belt


the tension looks like this


replacement is not too difficult. usually the bolt in the center turns opposite to how you normally loosen bolts. to remove the hole tension should be straightforward as you will see the bolts

I really hope helped with this. remember rated this help. Good luck.

1. Disconnect negative battery cable and remove coolant reservoir.
2. Remove serpentine belt. Refer to Drive Belts, Mounts, Brackets and Accessories / Drive Belt. See: Drive Belt\Service and Repair
3. Remove two generator bolts.
4. Remove power steering pump and position aside.
5. Remove tensioner bolts and tensioner.
6. Reverse procedure to install, Torquing tensioner bolts to 37 ft. lbs.

Remove the air filter housing and air hose. Set aside
Pull the 15mm bolt on the tensioner counterclockwise (towards front of car) and hold it there to loosen tension, and remove the serpentine belt.
With your 15mm wrench, unbolt the belt tensioner and remove.
Replace with new tensioner
Put serpentine belt back on.
Very easy! Be careful when releasing tension, becase if you let go of the wrench it will fly back and could hurt you.
