I found a diagram, but I'm not sure it's relevant. It's for a 2.0 motor w/ vin P.

Timing belt installation for EF 2.4L Sonata from http://www.hmaservice.com

1. Install the crankshaft sprocket "B" into the crankshaft.

Caution: Pay attention to the direction of the flange. If it is installed in the wrong direction, a broken belt could result.



2. Apply engine oil to the outer surface of the spacer lightly and then install the spacer to the right counter balance shaft. Be sure to installin the direction shown in the illustration.

3. Install the counter balance shaft sprocket onto the right counterbalance shaft and then tighten its flange bolt by hand tightly.



4. Align the timing mark on each sprocket with the corresponding timing mark on the front case.


5. When the timing belt "B" is installed, make certain that its tension side has no slack.

Install the tensioner "B" so the center of the pulley is located on the left side of the mounting bolt and in the pulley flange faces the frontof the engine.

Align the timing mark on the right counter balance shaft sprocket with the timing mark on the front case.



6. Lift the tensioner "B" to tighten the timing belt "B" so that its tension side is pulled tight. In this condition, tighten the bolt to secure tensioner "B". As the bolt is tightened, be careful to prevent the shaft fromturning. If the shaft is turned, the belt will be tightened excessively.



7. Check to ensure that the timing marks are in alignment.

8. Verify the tension of the timing belt.

Method 1 : Verify that, when the center of the span on the tension side is depressed with an index finger in the direction of arrow, the deflectionof the belt is within specification.
Belt deflection : 5 ~ 7 mm (0.20 ~ 0.28 in)

Method 2 : Measure the tension of the timing belt by using a tension gaugent.

Span length
Pressure
Torque
139mm (5.47 in.)
0.42 kg/cm²
(42 kPa)
50 ~ 100Nm
(500 ~ 1000kg.cm, 36 ~ 72 lb.ft)



9. Install the flange and crankshaft sprocket onto the crankshaft. Be sure to install the as shown in the illustration.

Caution: Pay attention to the direction of the flange. If it is installed in the wrong direction, a broken belt could result.



10. Install the special washer and sprocket bolt to the crankshaft and then tighten the sprocket bolt.

Tightening torque
Crankshaft sprocket bolt :
160 ~ 170 Nm (1600 ~ 1700 kg.cm, 116 ~ 123 lb.ft)

11. Insert a screwdriver through the plug hole in the left side of the cylinder block to keep the shaft in position.



12. Install the oil pump sprocket and tighten the nut to the specified torque.



Tightening torque
Oil pump sprocket
50 ~ 60 Nm (500 ~ 600 kg.cm, 36 ~ 43 lb.ft)

13. Install the camshaft sprocket and tighten the bolt to the specified torque.
Tightening torque
Camshaft sprocket bolt :
80 ~ 100 Nm (800 ~ 1000 kg.cm, 58 ~ 72 lb.ft)

14. Install the auto tensioner.

Caution: Leave the set pin installed in the auto tensioner.



Caution: If the auto tensioner rod is in its fully extended position, reset it as follows.

1.Clamp it in a vise equipped with soft jaws, in a level position. Use a plain washer if there is a plug at the bottom of the auto tensioner.

2.Compress the rod slowly with the vise until the set hole in the rod is aligned with set hole in the cylinder.



3.Insert a set pin through the auto tensioner body and rod.

Caution: Leave the set pin installed in the auto tensioner.

15.Install the tensioner pulley onto the tensioner arm.
Tightening torque
Tensioner pulley
43 ~ 55 N.m (430 ~ 550 kg.cm, 31 ~ 40 lb.ft)


16.Rotate the camshaft sprockets so that the dowel pin of the camshaft sprocket is at the upper side. Set the timing mark of sprocket correctly.

Caution:

1.Before installing the timing belt, if the timing mark of the camsprocket doesn't coincide with that of the rocker cover, do not rotate the cam sprocketmore than 2 teeth of the sprocket in any direction.
Rotating the sprocket more than 2 teeth may make the valve and piston touch each other.

2.If it is necessary to rotate the cam sprocket more than 2 teeth, rotate the crank sprocket counter clock wise first based on the timing mark.
After the camsprocket is properly timed return the crankshaft to TDC.



3.When exhaust and intake camshaft sprocket is used and install it after checking I.D mark depending on the engine deplacemeat.



17.Align the timing mark on each sprocket with the corresponding timing mark and install the belt as the following order.

Crankshaft sprocket - Oil pump sprocket - ldler pulley - Exhaust camshaft sprocket - Intake camshaft sprocket -Tensioner pulley



Caution:

1.Be sure that the piston of NO.1 cylinder is located in TDC position (Compression storke).

2.When aligning the timing mark on oil pump sprocket, remove the letf plug of cylinder block, and then check that the count balance shaft is in the specified position by inserting the screwdriver (Diameter : 8mm, insertinglength : 60mm or more)



3.After checking the timing mark, install the lift plug of cylinder block.
Tightening torque : 2.7 - 3.4 kgf.m
(Apply the liquid gasket : THREE BOND NO.1212B or equivalent)

18.Pull out the set pin.

19.Rotate the crankshaft two turns clockwise and leave it for about 5 minutes. Then, measure the auto tensioner protrusion "A" (Distance between the tensioner arm and auto tensioner body) to ensure that it is within thespecification.

Standard value : 5.5-9 mm (0.22 - 0.35 in)



20.Install the timing belt lower cover and the timing belt upper cover.
