Timing belt tensioner

its like the old gm top bolt loosen and the bottom bolt loosen then in the back of the pump you can pry with a bar or if the bolt is there you tighten it in to tighten the belt then you tighten all the other bolts after the belt is tight

Loosen pivot bolt and tensioner mounting bolt . Do not remove them.

Relieve tension on the drivebelt by rotating adjustment bolt .


Remove drive belt.

Remove tensioner mounting bolt and belt tensioner.

then the Alternator will barely slide out. (hope your motor mounts are good :P)

.6L (VIN 3) & 2.0L Engines

1. Before servicing the vehicle, refer to the Precautions Section.
   

2. Remove or disconnect the following:
   

   • Negative battery cable
     

   • Engine cover
     

   • Right-hand front wheel
     

   • Right-hand wheel well side cover
     

   • Accessory drive belts
     

   • Water pump pulley
     

   • Timing belt upper cover
     

3. Turn the crankshaft pulley so cylinder No. 1 is at Top Dead Center (TDC). Align the pulley groove with the timing mark "T" of the timing belt cover.
   

4. Remove or disconnect the following:
   

   • Crankshaft pulley
     

   • Crankshaft flange
     

   • Lower timing belt cover
     

   • Timing belt tensioner
     

   • Timing belt To install:Align the timing marks of the camshaft and crankshaft sprockets to ensure the No. 1 cylinder is at TDC.Temporarily install the timing belt tensioner.Install the timing belt over the crankshaft sprocket, then inside the idler pulley, over the camshaft sprocket and then inside the timing belt tensioner.Apply tension to the timing belt by turning the tensioner in the clockwise direction so there is no slack in the belt on the tension side.Tighten the tensioner mounting bolts to 20 ft. lbs. (27 Nm).Check the timing belt tension as follows:
     

1. • 1.6L (VIN 3) engine: Push the tension side of the belt in horizontally with a moderate force, the timing belt cog end is approximately 1/2 of the tensioner mounting bolt head radius away from the bolt head center.
     

   • 2.0L engine: Push the tension side of the belt in horizontally with a moderate force, the timing belt cog end sags approximately 0.16-0.24 inches (4-6 mm).
     

2. Turn the crankshaft two turns in the clockwise direction and realign the crankshaft sprocket and camshaft sprocket timing marks.
   

undo the alternator bolts and swing it inwards towards the block,replace the belt and lever the alt away from the block to tension it (1/2"play on longest stretch between pulleys) use ring spanners.(wrenches)

The belt tensioner has a heavy duty spring in it were it does not need any sort of adjustments done to it. If the tensioner seems loose to you, replace it before you loose your bely while driving

If it is the single overhead cam engine,it's pretty straight forward-Crank-tensioner- cam.The tensioner is a simple slide-to-tension type.You will need to take off the top engine mount for access(i just supported the engine with a jack)If it's a twin cam?Sorry don't know as mine is single cam.(obviously all air con belts,altenator belt etc have to be removed first)

Not sure what engine you have , but I had an 02 rio with the 1.5 L . The serpentine belt did not have a tensioner (spring loaded) pulley , the belt tightness was adjusted by pivoting the alternator mount.
If you are takling about the Timing belt , the tensioner pulley wont move (even though it is on a spring ) untill you loosen the bolt in the center.

Recommended by kia is 100,000 km.

Timing Belt: Service and Repair
TIMING BELT
COMPONENT
REMOVAL
1. Disconnect negative battery cable.
2. Loosen power steering lock bolts and nuts accordingly and remove tension from Power Steering (P/S) and/or Air Conditioning (A/C) compressor
drive belt.
3. Remove P/S and/or A/C drive belt.
4. Loosen generator mounting bolts and adjusting bolt.
5. Remove generator bolts.
6. Remove water pump pulley.
7. Remove crankshaft pulley and timing belt guide plate.
8. Remove upper and lower timing belt covers.
9. Turn crankshaft so that timing mark on timing belt pulley is aligned with timing mark on engine.
10. Check that "I" mark on intake camshaft pulley is aligned with mark on cylinder head cover and "E" mark on exhaust camshaft pulley is aligned
with mark on cylinder head cover.
NOTE: Do not move camshaft or crankshaft once timing marks have been correctly positioned.
11. Loosen tensioner pulley lock bolt.
12. Protect timing belt with a rag.
13. Remove tensioner pulley.
14. Remove timing belt.
NOTE: Mark the direction of timing belt rotation (on the timing belt) for proper reinstallation.
INSPECTION
NOTE: Never forcefully twist, turn inside out or bend timing belt. Do not allow oil or grease to come in contact with timing belt.
1. Replace timing belt if it is contaminated with oil or grease.
2. Check timing belt for uneven wear, fraying, peeling, cracking and hardening. Replace timing belt as necessary.
3. Bend timing belt into a "U" shape as shown in figure. Distance "A" must be at least 1.0 inch (25 mm).
4. Inspect both idler pulley and tensioner pulley for uneven wear and smooth bearing operation.
5. Inspect camshaft pulleys and timing belt pulley for broken teeth or damage.
NOTE: Replace any component that shows damage, excessive wear, or that appears prone to a possible failure.
INSTALLATION
1. Install tensioner pulley.
NOTE: Replace tensioner spring whenever timing belt is replaced.
2. Pull tensioner pulley to its furthest point and tighten lock bolt.
3. Check that timing mark on timing belt pulley is aligned with timing mark on engine.
4. Check that "I" mark on intake camshaft pulley is aligned with mark on cylinder head cover and "E" mark on exhaust camshaft pulley is aligned
with mark on cylinder head cover.
NOTE: If existing timing belt is being reused, install belt in proper rotation direction marked prior to removal.
5. Install timing belt onto timing belt pulley first, then idler pulley, exhaust camshaft pulley, intake camshaft pulley, and tensioner pulley in that
order.
6. Check that there is no looseness in belt between idler pulley and exhaust camshaft pulley or between intake and exhaust camshaft pulleys.
7. Loosen tensioner pulley lock bolt and allow tensioner spring to apply tension to timing belt.
NOTE: Do not add additional tension.

8. Tighten tensioner pulley lock bolt to specified torque.
Tightening torque: 28 - 38 ft. lbs. (38 - 51 Nm, 3.9 - 5.2 kg-m)
9. Rotate crankshaft two full revolutions (clockwise only) and align timing mark on timing belt pulley with timing mark on engine block.
10. Check that "I" mark on intake camshaft pulley and "E" mark on exhaust camshaft pulley are aligned with marks on cylinder head cover.
11. If they are not aligned, remove timing belt and start process from tensioner installation.
12. Measure timing belt deflection by applying moderate pressure midway between camshaft pulleys. If deflection is not correct, repeat from
tensioner installation.
Deflection pressure: 22 lb. (98 N, 10 kg)
Deflection: 0.39 - 0.50 inch (11 - 13 mm)
13. Install lower and upper timing belt covers in that order.
Tightening torque: 5.8 - 8.0 ft. lbs. (7.9 - 10.7 Nm, 0.8 - 1.1 kg-m)
14. Install timing belt guide plate and crankshaft pulley.
Tightening torque: 9.0 - 12.6 ft. lbs. (12.3 - 17.2 Nm, 1.3 - 1.8 kg-m)
15. Install water pump pulley.
Tightening torque: 9.0 - 12.6 ft. lbs. (12.3 - 17.2 Nm, 1.3 - 1.8 kg-m)
16. install generator belt and adjust the tension.
17. Install P/S and/or A/C drive belt and adjust the tension.
18. Connect negative battery cable.

If you are planning on replacing the timing belt and are not even sure where to find on the engine then please DONT attempt to replace it on your own. Replacing the timing belt requires knowledge of timing marks and tensioner adjustments. It does not simply come off and back on, it has to be aligned up properly with marks on the camshaft and crankshafts. Please leaave this to someone who knows! PS: the timing belt is located behind the plastic covers on the left hand side of the engine (looking from the front)

1.8 hours. dont forget to consider changing the water pump and tensioner.
