2001 toyota avalon timing belt out of adjustment

I have included an image for reference. There is a tensioner included in the pulleys the belt travels around. (Red X). There is also a spring loaded lever point you use to release the tension on the belt.
Remove the covers to expose the belt. **Take a photo or draw the route the belt takes so you don't forget when putting the new one back on.**
Facing the belt and using a ring spanner or swan neck spanner, turn the adjuster clockwise, (green circle). **NOTE** There will be a lot of tension on the spring so take your time as it could slip and snap back into place, taking at least one knuckle with it. I always find a helper at this point makes the whole thing A LOT easier.
Once the adjuster is swung over the belt should slide off one of the pulleys and then off completely. Gently ease the adjuster back to it's rest position.
Replace as follows. Using your reference image and your helper, swing the adjuster clockwise as far as you can. Position the belt, making sure it is squarely positioned on each pulley. GENTLY ease the adjuster back off and recheck it is squarely set on all the pulleys.
At this point you can start the vehicle to check the belt in running correctly then after turning the engine OFF refit any covers over the belt.

Timing belt.

it must be bad, or loose. just like all locks.
find a real mechanic that can touch it , and see what part is failing, i cant see yours, so cant guess, (physical worlds)

1: BAD LATCH OR LINKAGE
2:;DOOR AJAR, CANT CLOSE.
3: LATCH TRIPPED BY KIDS ,NEEDS RESET( Some can)

look for damage

Almost certainly one or more of the drive belts (not the timing belt) on the engine needs an increase in tension. It may tell you about this in the owner's handbook.

If not you can either ask a mechanic to do this straightforward job for you, or try it yourself. You can download a zipped service manual from here

and look these belts up in the charging section and steering section.

Disconnect the battery before starting the job! Your power cable from the alternator will be disconnected and could potentially ground out if your battery is not disconnected!

1. REMOVE DRIVE BELT Loosen the pivot bolt, adjusting lock bolt and adjusting bolt, and remove the drive belt.

1. REMOVE GENERATOR

1. Disconnect the generator connector.
2. Remove the nut, and disconnect the generator wire.
3. Disconnect the wire harness from the clip, unplug.
4. Remove the pivot bolt, plate washer, adjusting lock bolt and generator.

There are two bolts on the alternator:
One holds it in position on a rail to adjust belt tension and the other mounts it to a brace. Loosen both of these and angle the alternator to release the belt tension and remove the belt. Put the new one on and reverse your removal technique. You want the belt taut, but not tight. If it squeals when it's running, just adjust the tension to make it a little bit tighter.

go to toyota buy a fan belt, i think u can see a belt adjuster need the belt and engine , you just need to adjust the belt to very good tension

Make sure you routed it correctly. One of the most common mistakes I make is trying to put belt around a tensioner that belt just rides on. Hope that helps.

she really shouldnt worry about it hate to say , but do have a question i know its a avalon and all but do you have a trailer hitch with harness on the car wouldnt ask if i havent seen it before i work at toyota dealer as a mechanic and when they wire the harness for the hitch they tap into the light circuit causes the flickering hope this helps

the pulley that doesn't appear to drive anything is the tensioner
