Adjustment on belt?

I wondered the same thing and looked for days on end. To my surprise, there is no tension pulley for the 2003 Kia Spectra. The Kia 4 cyl has two (2) belts. The outside belt services the power steering and air conditioning. The inside belt (the one you want to service) services the alternator and water pump. The alternator tension is set by two (2) adjustment screws located on the alternator. One screw is used as a locking bolt and the upper bolt is used as the adjuster. You must first loosen the locking bolt which is located between the belt and the alternator housing. Loosen about 6 to 8 travels of the wrench (size 13mm), then tighten the upper bolt until you have no more than 1/2 inch of movement in the belt when you press down. After the correct tension is achieved, tighten the locking bolt and your done. As long as you're down there, you might as well check the outer belt as well. Same principle, one locking and one adjuster. Good Luck, Fred

Remove the alternator/power steering pump and water pump drive belt to gain access to the air conditioning drive belt.
To remove and install the air conditioning compressor drive belt, first loosen the tensioner pulley lock nut, then turn the adjusting screw to raise or lower the tensioner pulley assembly Accessory Drive - 3.3L Engine or Accessory Drive - 3.5L Engine To adjust the air conditioning drive belt, loosen the tensioner pulley nut and adjust belt tension by tightening adjusting screw. Torque pulley nut to 54 N•m (40 ft. lbs.) after adjustment.
The Poly-V generator/power steering belt has an adjustable tensioner pulley located on the timing belt cover Accessory Drive - 3.5L Engine to maintain proper belt tension. To remove or install this belt, Release tension by loosening the tensioner pulley nut and adjustment bolt Accessory Drive - 3.5L Engine Reverse procedure to install and tighten belt to specified tension.

Belt Tensioner Operation:
This device functions as an idler pulley and is located on either the inside or outside of the accessory drive belt. Its provides the correct tension for initial belt adjustment and maintains this critical tension adjustment during vehicle operation. It can be found on conventional V-belts and the newer serpentine ribbed belts.

The tensioner pulley looks like an idler pulley, only with an adjusting bolt protruding out about 2 inches from just behind the pulley. Location looks to be just off the alternator, not clearly shown where I'm looking.
To loosen belt, you loosen the tensioner pulley nut, and then turn the adjusting bolt in to relieve tension. When putting the belt back on, adjust tension with adjustment bolt, then tighten the pulley nut. This is for Sebring Coupe, Convertible is different. Good luck.

the tensioner is located directly below where the alternator bolts on. it is an automatic adjusting tensioner so you can't adjust it . you can only move the pulley back and forth to allow slack in the drive belt.

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

ADJUSTMENT 1.8L Engines ALTERNATOR AND WATER PUMP BELT

1. Loosen the alternator adjusting bolt.
2. Raise and safely support the vehicle.
3. Loosen the alternator mounting bolt. NOTE: Do not pry against the stator frame. Position the prybar against a stronger point, such as the area around a case bolt. Fig. 1: A belt tension gauge should be placed on the longest span of the belt to check tension — 1.8L engine
   
   
4. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
5. Adjust the tension to 86–103 lbs. (383–461 N) for a new belt or 68–86 lbs. (304–383 kg) for a used belt.
6. If a belt tension gauge is not available, adjust the tension to 0.31–0.35 in. (8–9mm) deflection for a new belt or 0.35–0.39 in. (9–10mm) deflection for a used belt.
7. Tighten the alternator adjusting bolt to 14–19 ft. lbs. (19–25 Nm).
8. Tighten the alternator mounting bolt to 27–38 ft. lbs. (37–52 Nm).
9. Lower the vehicle. Fig. 2: Alternator and water pump pulley belt routing — 1.8L engine
   

POWER STEERING PUMP BELT

1. Raise and safely support the vehicle.
2. Loosen the power steering pump mounting bolt and nuts.
3. Adjust the power steering pump and, if equipped, the air conditioning compressor belt tension by turning the pump adjusting bolt. Fig. 3: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models without A/C
   
   
4. Tighten the power steering pump mounting nut near the pump adjusting bolt.
5. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
6. Adjust the tension to 110–132 lbs. (491–589 N) for a new belt or 95–110 lbs. (422–491 N) for a used belt.
7. Check for proper belt deflection. For a new belt (one with less than 10 minutes of run time), the deflection should be 0.31–0.35 in. (8–9mm). For a used belt (one with more than 10 minutes of run time), the deflection should be 0.35–0.39 in. (9–10mm).
8. Tighten the power steering pump mounting nut, located near the adjusting bolt, to 27–38 ft. lbs. (37–52 Nm).
9. Tighten the pump mounting bolt behind the pulley to 27–40 ft. lbs. (36–54 Nm), and the remaining pump mounting nut to 23–34 ft. lbs. (31–46 Nm).
10. Lower the vehicle. Fig. 4: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models with A/C
    

1.9L Engines The accessory drive belt for 1.9L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner. NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension. Fig. 5: Drive belt routing — 1.9L engines
2.0L Engines The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner. NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension. The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced. Fig. 6: Drive belt routing — 2.0L SOHC engine with A/C
Fig. 7: Drive belt routing — 2.0L SOHC engine without A/C
Fig. 8: Drive belt routing — 2.0L DOHC engine

This uses a self adjusting tensioner.This vehicle should have a series II 3.8L.The adjuster is located just under the alternator and slightly to the right.If trying to remove the belt a 15mm headed bolt runs through the tensioner pully turning it counter clockwise should loosen the belt tension.

TY for using Fixya; remember comment and rated this.

Serpentine belf is self adjusting the tensioner is spring loaded no adjustment, if weak replace it.If belt was replace make sure you have the right size belt, before replace tensioner.
