Recommendation. Since valves and pistons may collide if the timing belt breaks, the timing belt must be replaced every 60,000 km. When replacing the timing belt, its tensioner and idler rollers should also be replaced.
Camshaft drive scheme:
1 - toothed pulley of the crankshaft of the engine;
2 - tide on the cover of the oil pump;
3 - toothed pulley of the coolant pump;
4 - tension roller;
5 - gear pulley of the exhaust camshaft;
6 - rear timing belt cover;
7 - a gear pulley of a camshaft of inlet valves;
8 - guide roller;
9 - toothed belt;
A - TDC mark on the crankshaft toothed pulley;
B - mark on the cover of the oil pump;
C, F - mark on the rear cover of the timing belt;
D - mark on the gear pulley of the exhaust camshaft;
E - mark on the gear pulley of the intake camshaft.
Removing
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
2. Remove the upper front timing belt cover (see «Timing Belt - Checking Condition»).
Advice. If you remove the timing belt not for replacement, mark the direction of its rotation with a marker. When assembling, it should be installed in accordance with the label.
3. Remove the front right wheel (see «Wheel - replacement») and put the car on a secure stand.
4. Remove the right side of the engine mudguard.
5. Remove the alternator drive belt (see «Alternator drive belt - condition check and tension adjustment»).
6. Turn the crankshaft with a 17 mm socket wrench until the marks on the exhaust camshaft pulley align...
...and on the intake camshaft pulley with marks on the rear timing belt cover.
Comment. This position will correspond to the position of the crankshaft at TDC on the compression stroke of the first cylinder (see fig.). It is not allowed to rotate the crankshaft by the bolts of the camshaft pulleys. When performing the following operation, the crankshaft can be held with a slotted screwdriver by the flywheel ring gear. To do this, unscrew the three screws and remove the bottom cover of the clutch housing (see «Oil pan - removal, gasket replacement and installation»). Also, the crankshaft pulley bolt can be unscrewed if the assistant engages a higher gear and presses the brake pedal. However, the crankshaft may rotate slightly. Therefore, you need to re-verify that all labels match.
7. Using a 17 mm socket wrench with an extension, unscrew the bolt securing the crankshaft pulley.
8. Remove the crankshaft pulley and restrictive washer.
9. With a 5 mm hex wrench, unscrew the three bolts securing the lower front cover of the timing belt.
10. Remove the cover.
11. With a 15 mm wrench, turning the tension roller mounting bolt half a turn counterclockwise, loosen the timing belt tension.
12. Remove the timing belt.
Recommendation. After removing the belt, check the condition of the tension and guide rollers (see «Timing belt tensioner and guide rollers - check and replace»).
Installation
1. We put on a new belt, laying its branches in accordance with the figure, and making sure that the mark on the crankshaft toothed pulley is located opposite the tide made on the oil pump housing.
2. We put the belt on the intake camshaft pulley so that the front branch of the belt is taut. Without letting the belt loosen, we put it on the exhaust camshaft pulley.
3. With a puller for retaining rings, turn the tensioner in the direction of the arrows until the marks on it align...
... and with a 15 mm key we tighten the tension roller mounting bolt with a torque of 33.2-41.2 Nm (3.4-4.2 kgf·m).
4. If at the same time one of the camshafts has turned, then loosen the belt and reinstall it by turning the incorrectly installed camshaft (allowable mismatch of marks within one tooth of the camshaft pulley).
5. Turning the crankshaft two turns (behind the flywheel ring or by screwing the pulley mounting bolt into the shaft), we are convinced by the coincidence of the marks that the mutual position of the shafts is not violated. If necessary, aligning the marks, repeat the installation of the belt.
6. After combining all the marks, we install the parts removed from the car in place.
