An assistant is required to complete the work, and it is also desirable to have a viewing ditch.
Recommendation. The work is labor intensive and requires special equipment and skills. Access to the belt is difficult due to the tight layout in the engine compartment. To remove the timing belt cover, you need to remove the right engine mount, and for this, the engine must be partially suspended. Therefore, if you are not confident, have this work done at a specialized service station.
Recommendation. Since when the timing belt breaks, valves and pistons may collide, the timing belt should be strictly observed when replacing the timing belt. When replacing the timing belt, its tensioner and idler rollers should also be replaced.
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 above, «Timing Belt - Checking Condition»).
Recommendation. 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 front fender liner on the right side of the car.
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
5. Remove the alternator drive belt (see «Accessory drive belt - replacement»).
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. This position will correspond to the position of the crankshaft at TDC on the compression stroke of the first cylinder (see fig.).
Warning! It is not allowed to rotate the timing belt by the bolts of the camshaft pulleys.
1. Using a 17 mm socket wrench with an extension, unscrew the bolt securing the crankshaft pulley.
Comment. When performing the 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 starter (see «Starter - removal and installation»), Also, on a vehicle with a manual gearbox, the crankshaft pulley bolt can be loosened if an assistant shifts into a higher gear and depresses the brake pedal. However, the crankshaft may rotate slightly. Therefore, you need to re-verify that all labels match.
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: one on top...
...and two below.
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 from the pulleys and remove from the engine compartment.
Recommendation. After removing the belt, check the condition of the tension and guide rollers (see below, «Timing belt rollers - replacement»).
Installation
1. We put on a new belt, laying its branches in accordance with the pattern (see above), and making sure that the mark on the crankshaft sprocket is opposite the lug 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. Snap ring puller (placing them in grooves 1) turn the tensioner in the direction of the arrows until marks 2 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), for clarity shown on the removed engine.
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.
