Removal
Warning! Turn the crankshaft clockwise and align the timing marks so that the piston in the first cylinder is located at top dead center in the compression stroke. At this time, the timing marks of the camshaft pulley and cylinder head cover should be aligned, and the camshaft pulley alignment pin should be at the top.
1. Remove the poly V-belt and crankshaft pulley.
2. Remove the timing belt cover.
3. Remove the engine mount bracket.
4. Using the head of the large bolt, turn the timing belt tensioner until the support plate aligns with the hole in the casing, then insert the retainer into the hole.
5. Use the Allen key to loosen the locking bolt.
6. Using the head of the large bolt, turn the timing belt tensioner mechanism clockwise until it stops.
7. Tighten the locking bolt.
8. Remove the timing belt.
Caution: Mark the direction of rotation of the timing belt to reinstall it in its original position.
9. Unscrew the pivot bolt and remove the automatic timing belt tensioner mechanism.
Examination
Pulleys, timing belt tensioner pulley and idler pulley
1. Check the camshaft and crankshaft pulleys, tensioner pulley and idler pulley for uneven wear, cracks and damage. Replace them as needed.
2. Check the ease and smoothness of rotation of the tension pulley and the idle pulley, as well as the absence of extraneous noise during rotation. Replace them as needed.
3. Replace pulleys if there is lubricant leakage.
Automatic timing belt tensioning mechanism
1. Check the automatic timing belt tensioner for leaks and replace it if necessary.
(Material was obtained from an official resource: «HyundaiBook.ru»)
2. Check the tip for wear or damage and replace it if necessary.
Toothed belt
1. Check the timing belt for any traces of oil, water or dust. Replace the belt if necessary. Minor marks should be wiped off with a dry cloth or paper. Do not clean the timing belt with solvent.
2. After repairing the engine or adjusting the belt tension, check the condition of the belt. If the following defects are present, replace the timing belt.
Installation
1. Install the crankshaft pulley onto the crankshaft.
Warning: Pay special attention to the installation direction of the flange. If the pulley is installed incorrectly, it will cause damage to the timing belt.
2. Install the special washer and screw in the bolt securing the pulley to the crankshaft, and then tighten the bolt. Tightening torque: 185–195 Nm.
Toothed belt
1. Check the position of the alignment marks.
- crankshaft side: timing mark on crankshaft pulley and injection timing rod;
- from the camshaft side: timing mark on the camshaft pulley and cylinder head.
2. Install the tensioning mechanism.
3. Install the automatic timing belt tensioner mechanism.
4. Tighten the hinge bolt. Tightening torque: 50–55Nm.
5. Install the timing belt.
| Description | Defect | |
| 1. Rigid back surface of the toothed belt |  | The surface has a glossy appearance. The surface is so hard that your fingernail won't leave marks on the belt |
| 2. Cracks on the back surface of the timing belt |  | |
| 3. Cracks or delamination of the timing belt |  | |
| 4. Severely worn teeth |  | The side of the tooth is worn, exposing the fibers, cord and rubber base |
| 5. Severely worn teeth (last stage) |  | The side of the tooth is worn out, with abrasions becoming visible and the thickness of the tooth is reduced |
| 6. Cracks in the base of the teeth |  | |
| 7. Missing tooth |  | |
| 8. Severe wear on one side of the belt |  | A normal belt should have a smooth side edge, as if cut with a sharp knife |
| 9. Cracks on the side of the timing belt |  | |
6. Loosen the locking bolt, this will move the tension mechanism lever and automatically tighten the toothed belt.
7. Turn the engine crankshaft clockwise two revolutions and check the alignment of the timing marks.
8. Tighten the locking bolt.
9. Remove the retainer.
