How to remove belt tensioner???

I`m pretty sure your belt tensioner pully is just held on with a couple bolts.Remove your serpentine belt,your main belt.look at the pulley see where the bolts are that hold it on and remove them.They are spring loaded so when u take it off make sure you have the new one to put on because once you remove it ,it is no good and have to put the new one on.

hi there, here is what i have found for you, i hope it helps:

Look at where the drive belts are located on your Mitsubishi Galant. Depending on models, you may need to jack up the vehicle to access the bolts for the belts.

Find the bolt assembly for the belt. This bolt structure will be on or near the main component that the belt serves. Look at all of the pulleys around which the belt winds, and you will find a bolt system to adjust tension. For an alternator belt, the bolt system is by the alternator. For a power steering belt, look near the power steering pump.

Find the lock nut that holds the long adjustment bolt in place and use your wrench to loosen it. This is the bolt the loosens the belt tension so that you can remove it.

Turn the adjustment bolt. Turning the adjustment bolt moves the component either toward the engine in order to loosen belt tension, or away from the engine in order to tighten belt tension.

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.

cheers

if it dont have an auto spring you need to loosen the bolts on the alternator and swing it in toward the engine,fit the belt then swing it out to tighten the belt before you do up the alt bolts NOT TOO TIGHT,

yes you are correct the alternator needs to be loosened to remove the belts. You are going to need to get a flat wrench or box wrench in there to loosen the bolts. Both need to be loosened to move the alternator. By the way screeching belts are a known problems for the 2.0 motors, so make sure you get a good belt so it doesnt happen anymore.

it isnt that hard actually

disconect positive battery terminal. and feel the tension on the laternator belt. you will need to bring it back to this tension.

1.) loosen bolts holding alternator in place (LOOK AT THE BELT TO REMEMBER HOW IT GOES, BEST NOT REMOVE THE BELT.)

2.) loosen bolts holding wires to alternator and connect wires to new alternator

3.) Place alternator in engine, replace bolts but dont tighten

4.) put belt in place, it will be slack, use your tire iron or a piece of pipe or wood to pry the alternator back, to bring tension on the belt. You pry the alternator to pull the belt as TIGHT AS POSSIBLE. while holding strain, on it, tighten the bolts.

It's common for the serpentine tension pulley to fail and will need to be replaced, Auto Zone or NAPA carry the tension pulley you need for your Impala and it's a 15 min job to replace the part. The tension pulley is held on by one bolt through the center of the base of the tension arm and can only be installed one way. Just un-bolt and remove the faulty tension arm, just make sure you have taken the serpentine belt off and might as well replace it since you have it off any ways and keep the old on in the truck. Good luck and hope this helps.

hELLO THERE:
NO YOU DO NOT WANT TO LOOSEN THIS BOLT LOOK FOR THE SMALL SQUARE HOLE THAT A SOCKET EXTENSION FITS INTO THIS IS THE HOLE THAT YOU ARE WANTING TO USE AND THEN PUSH IT OVER TO THE DRIVERS SIDE TO MAKE THE TENSIONER LOOSEN THE TENSION ON THE BELT SO YOU CAN REMOVE IT OK

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable (both on diesels).
2. Release tension and remove the drive belt.
3. Disconnect the wiring harness at the plastic connector.
4. Remove the output terminal nut(s) and disconnect the output cable.
5. On diesel engines: loosen, but do NOT remove, the alternator bracket-to-engine bolt.
6. Remove alternator mounting bolts. Note any shims or spacers in the assembly.
7. Carefully remove the alternator from the engine.

To install:

1. Position the alternator on the engine. Be sure to install any shims or spacers.
2. Install the alternator mounting bolts and tighten to 40 ft. lbs. (54 Nm) for 2.5L and diesel engines, 30 ft. lbs. (41 Nm) for others.
3. Connect the electrical harness. Connect the output cable and tighten the nut.
4. Install and the accessory drive belt and check tension.
5. Connect the negative battery cable.
6. Check the alternator for proper operation.

Tensioner must be moved to loosen belt
Use a socket and breaker bar to rotate the tensioner and remove the serpentine belt. (see pic)

It is the belt tensioner pulley.
The bearings are worn out. Quite easy and cheap to replace

yes remove one bolts where caliper bolts to the slide assembly older models had allen heads
