Timing belt “B” (balancer belt) and related components—2004–2005 Galant and 2004–2005 Lancer 2.4L engine
Disconnect the negative battery cable. Remove the engine under cover.
Remove the crankshaft damper pulley.
Disconnect the control wiring harness connector, battery wiring harness connector and connector bracket to engine mounting insulator.
Remove the harness bracket. Remove the upper timing belt cover. Remove the water pump pulley. Remove the idler pulley.
Remove the auto tensioner. Remove the lower timing belt cover.
Turn the crankshaft clockwise and align each timing mark to set the number one piston to TDC of its compression stroke.
Remove the timing belt under cover rubber plug and then install special tool MD998738. Screw the special tool until it contacts the timing belt tensioner arm.
The special tool must be screwed in gradually at the rate of a 30 degree turn per second. If it is screwed in all at once, the timing belt tensioner adjuster rod will not easily retract and the tool may bend.
Gradually screw in the special tool and then align the timing belt tensioner adjuster rod set hole “A” with the timing belt tensioner adjuster cylinder set hole “B”.
Insert a wire or pin in the set holes to lock the assembly in place. After removing the special tool, loosen the timing belt tensioner pulley mounting bolts and remove the timing belt. If the belt is being reused be sure to mark the direction of rotation (clockwise) on the belt.
Remove the timing belt tensioner pulley, tensioner arm and adjuster.
Remove the timing belt idler pulley. Remove the timing belt lower cover bracket. Remove the crankshaft position sensor.
Remove the crankshaft pulley center bolt and washer. Remove the drive sprocket. Remove the crankshaft angle sensing blade.
Remove the balancer timing belt tensioner. Remove the timing belt “B” (balancer belt) from its mounting.

You are asking how to remove the serpentine belt on your 3800 engine ?
First, I would take several pictures so you know how it goes back on.
1) * You must have a special idle pulley tool. Take you tool and pry the idle pulley enough to remove belt, dispose of old belt.
2) Now place the new belt on the pulleys just as you see in the pictures you took or look at the diagram on the radiator support.
3) Pull the idle pulley again with your tool and put on the belt.
The idle pulley will put the tension in the belt.
Please let me know how it went.
Alternator: Service and Repair Generator Replacement GENERATOR REPLACEMENT REMOVAL PROCEDURE CAUTION: - Refer to Battery Disconnect Caution in Service Precautions. - Failure to observe step 1 may result in a serious personal injury. If a tool is shorted at the generator lead, the tool will become hot enough to cause a serious burn. 1. Disconnect the negative (-) battery cable. 2. Loosen the belt tension by turning the drive belt tensioner clockwise. 3. Remove the drive belt. 4. Disconnect the wire clamp (3) from the wire clip. 5. Remove the terminal cap and nut (1). 6. Disconnect the engine wire. 7. Disconnect the generator connector (2). 8. Remove the two mounting bolts. 9. Remove the generator (4). INSTALLATION PROCEDURE 1. Install the generator (4) to the vehicle. NOTE: Refer to Fastener Notice in Service Precautions. 2. Secure the generator with the two generator mounting bolts. Tighten - Tighten the upper bolt to 25 N.m (18 lb ft). - Tighten the lower bolt to 54 N.m (40 lb ft). 3. Connect the generator connector (2). 4. Connect engine wire to the generator. 5. Secure the engine wire with the nut. Tighten Tighten the nut to 9.8 N.m (86 lb in). 6. Install the terminal cap (1) to the nut. 7. Install the wire clamp (3) to the wire clip. 8. Install the drive belt. - Visually inspect the drive belt for wear and damage. - Minor cracks on the ribbed side of the belt are considered acceptable. Replace the belt if pieces are missing from the ribs. - Ensure that the belt tensioner moves downward when the belt is pressed down in the center with a force of approximately 98 N (22 lb). 9. Connect the negative (-) battery cable. Tighten Tighten the bolt to 15 N.m (11 lb ft).
Check on upper rad shroud or under hood for routing diagram. Depending on what engine, procedure may vary a little. I wouldn't panic on replacing anything other than belt unless you noticed something noisy under hood in last while. If not up to it, a mechanic should be able to do it for you in a few minutes usually, but won't hurt to ask before, just in case.
if you get a 3/8 in socket wrench there is a square on the belt tensioner u can insert the scoket wrench into you will need a fairly long pipe to help with leverage then pull the wrench up and you will see the tensioner take off the tension off the belt so u can remove the belt but do not forget how the belt is routed this is the fun part ... autozone and kragen have special tools that you can rent to get the other bolts off of the alternator
