Timing belt
1. Upper timing belt cover; 2. Camshaft sprocket; 3. Upper intermediate pulley; 4. Spring; 5. Upper intermediate pulley; 6. Oil pump sprocket; 7. Crankshaft sprocket; 8. Timing belt guide; 9. Gas distribution belt; 10. Lower timing belt cover; 11. Crankshaft pulley
Removing
1. Disconnect the negative battery cable.
2. Block the rear wheels and put the car on the handbrake.
3. Raise and secure the front of the vehicle.
4. Remove the right front wheel and wheel arch gasket.
5. Remove the expansion tank of the engine cooling system.
6. Remove the spark plugs and remove the drive belts.
7. Remove the generator and its bracket.
8. Establish a support under the engine, remove the right support of the engine and draft regulating displacement of the engine.
9. Unscrew the screws of the top cover of the timing belt and disconnect the wires from it. Remove the top cover and gaskets.
10. Set piston N1 to top dead center. Check that the small hole in the camshaft sprocket is aligned with the timing mark on the first shaft bearing cap.
11. If you are going to reuse the timing belt, make alignment marks (arrows) on it and on the stars. Mark the direction of rotation of the belt.
12. Loosen the upper intermediate pulley bolt (arrow) and remove the spring. Remove the belt from the camshaft sprocket. The belt does not have to be removed from the crankshaft sprocket if you are going to replace the camshaft oil seal or remove the cylinder head.
13. If the camshaft sprocket is worn or damaged, remove the cylinder head cover, lock the intake camshaft with a wrench, and remove the sprocket bolt. Take off the star.
14. Remove the flywheel inspection cover, and lock the flywheel or drive plate with a large screwdriver. Loosen the crankshaft pulley bolt.
15. Unscrew the bolt and remove the pulley.
16. Remove the bolts (arrows) and remove the lower timing belt cover and gaskets. Remove the belt guide from the crankshaft sprocket.
17. If you are going to reuse the timing belt, make alignment marks (arrow) on it and on the star.
18. Remove the timing belt. If the crankshaft sprocket is damaged or worn or you need to replace the front crankshaft oil seal.
19. Take off the star. She must be free to act.
20. If the sprocket is stuck, remove it with a special tool.
Examination
Timing belt damage
1. Bundle; 2. Lack of teeth; 3. Surface wear; 4. Rounding the side
1. Remove idler pulleys and inspect their bearings for wear and damage. Inspect the spring, check if its length meets the specifications.
2. If the timing belt has broken, the cause may have been that it was too tight or dirty.
3. If the belt teeth are cracked or missing in some places, it is necessary to check whether the camshafts or the water and oil pumps are sticking.
4. If the belt surface is severely worn or cracked, check the intermediate pulley surfaces for scratches or burrs.
5. If the belt is worn or damaged on only one side, check the belt guide disc and the sprockets for correct installation.
6. If necessary, replace the belt, having previously eliminated all faults.
Installation
1. Thoroughly clean the front of the engine.
2. Install intermediate pulleys and spring.
3. Check if the timing marks of the crankshaft and camshaft are aligned.
4. Put the belt on the crankshaft sprocket, oil and water pump sprockets and idler pulleys. If you are putting on an old belt, align the marks made on the belt and on the sprockets during removal.
5. Install the belt guide on the crankshaft (on the image. belt guide shown).
6. Install the lower belt cover and crankshaft pulley.
7. Put the belt on the camshaft sprocket. Pull on the front of the belt.
8. Loosen the upper intermediate pulley bolt 1/2 turn, slowly turn the crankshaft clockwise 1 and 7/8 turns until the mark on the crankshaft pulley is 45°from the mark for setting the first piston to top dead center and located on bottom cover of the belt. Tighten the intermediate pulley bolt.
9. Turn the crankshaft two more turns and check if the timing marks are aligned.
10. Install new sealant gaskets to the timing belt covers.
