Re: 2001 montero sport replace air condition belt
There should be a nut on the front of the pulley loosen it off a few turns then there should be a bolt behind the pulley facing down also loosen this which should be your belt adjustment. hope this helps

Misalignment, wrong size belt, something is in contact with the belt and causing premature wear. A pulley may be seizing up within the belts route. Or cheap belts, but that usually isn't one of the answers.
It's under the timing cover on the front of the engine. I have pasted autozone.com instructions to replace the water pump below.
3.0L & 3.5L Engines
Before servicing the vehicle, refer to the Precautions section.
If necessary, properly release the fuel pressure.
Drain the cooling system.
Remove or disconnect the following:
Negative battery cable
Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.
Upper radiator shroudAccessory beltsAir conditioning compressor tensioner pulley, if equippedCooling fan and clutch assembly and the water pump pulleyThermostat and housing on 3.0L, 3.5L enginesWater outlet, gasket and housesRadiator hoses from the water pumpCrankshaft pulley(s)Timing belt covers. If the same timing belt will be reused, mark the direction of the timing belt's rotation, for installation in the same direction. Be sure the engine is positioned so the No. 1 cylinder is at the TDC of its compression stroke and the sprockets timing marks are aligned with the engine's timing mark indicators.Timing beltWater pump bolts are different lengths, note their positions before removing.Water pump from the blockWater pipe connection and O-ring
Clean and dry the mating surfaces of the block and water pump
Install or connect the following:
New O-ring on the water pipe connection, wet the new O-ring with water to aid in installationWater pump, with a new gasket, Torque the bolts to 17 ft. lbs. (23 Nm) on 3.0L and 3.5L enginesAlternator bracket bolt to 17 ft. lbs. (23 Nm)Timing belt(s) and coversCrankshaft pulley(s)Thermostat and housing on 3.0L, 3.5L engines. Torque the bolts to 12-14 ft. lbs. (17-20 Nm).Radiator hose to the water pumpWater outlet, new gasket and houses. Torque the bolts to 12-14 ft. lbs.

Refill the radiator with coolant. This cooling system has a self-bleeding thermostat, so system bleeding is not required.
Run the vehicle until the thermostat opens and fill the overflow tank. Check for leaks.
Once the vehicle has cooled, recheck the coolant level.
on the engine between the a/c compressor and crank pulley is adjusting pulley its above both of them in the middle loosen the 14mm nut on front of the pulley and turn the 12mm adjusting bolt clockwise until the belt is tight but not too tight if it continues to squeal just replace the belt you do not have to take any other belts off to replace
Please confirm to me but I believe the alternator is driven with the serpintine belt. If this is the case there is an idler/tension pulley that would need to be first loosened (I believe it is a 14MM) then at the top of the bracket where this pulley is mounted there is a bolt that you rotate to either loosen or tighten the belt (by turning this bolt you either raise or lower the pulley.
I hope this may have helped,
the chirping noise you hear are the belts being loose,adjust the tension on the belts,if the pulley bolt has not loosened up by now ,you dont have a bolt problem-when you have the timing belt replaced ,have the mechanic put some lock-tite on the bolt
you dont need remove the fan or the fan shrow you can put the belt on by looping the belt partially on a fan blade and then turnning the fan blade kinda like a bicycle chain and if it is the power steering belt there is a guard over the top of the pulley just remove the 2 10 milimeter bolts and it will come right off
