PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. On models with the amplifier of steering take off a driving belt of the pump of the amplifier of steering.
3. Take off a driving belt of the generator.
4. On C16 NZ2 1,8 and 2,0 engines of l disconnect the electric socket from the sensor of the index of temperature.
5. Release brackets of fixing or unscrew screws with six-sided heads and remove the main external casing of a gear belt (see rice. Removal of the main external casing of a gear belt).
6. Then disconnect a smaller casing from the water pump (see rice. Removal of a smaller casing of a gear belt from the water pump on the engine of 2,0 l). On some models the basic external casing fastens three bolts to a back casing, and the fourth bolt also the tension mechanism fixes (see rice. Arrangement of bolts of fastening of a basic casing).
7. On models of 1,6 l with the amplifier of steering remove the pump of the amplifier of steering.
8. For a bolt of fastening of a pulley turn a bent shaft before combination of an adjusting tag on a camshaft pulley with a groove in a back cover of a gear belt (see rice. Combination of a tag on a camshaft pulley with a groove in a back casing of a gear belt) and tags on a pulley of a bent shaft – with the index on a back cover of a gear belt (see rice. Combination of a tag on a pulley of a bent shaft with the index on a back casing of a gear belt on the engine of 2,0 l, Combination of a tag 10 ° to VMT on a pulley of a bent shaft with the index on a back casing of a gear belt on the engine of 1,4 l). On the engine 1,4 there are two tags on a pulley of a bent shaft noted as 5 ° and 10 ° to the top dead point. At the same time it is necessary to combine with the index a tag 10 °.
9. Weaken three bolts of fastening of the water pump and turn the pump so that to reduce a tension of a gear belt. Take off a gear belt from a camshaft pulley (see rice. Unscrewing of a bolt of fastening of the water pump on the engine of 2,0 l).
10. On l engines 1,4 and 1,6 except the C16 NZ2 engine the pulley of a bent shaft fastens one central bolt which also fixes a pulley of a gear belt. On l C16 NZ2 engines 1,8 and 2,0 the pulley fastens four bolts which need to be unscrewed a face key. Unscrew a bolt of fastening of a pulley of a bent shaft. For prevention of rotation of a bent shaft on models with the mechanical transmission, the assistant has to include any transfer and press a brake.
11. Remove a pulley of a bent shaft and take a gear belt.
12. For removal of a pulley of the camshaft disconnect a hose of ventilation of a case from a cover of a head of the block of cylinders, then unscrew bolts and uncover a head of the block of cylinders, a predvaritel but having noted an arrangement of arms of fastening of high-voltage wires.
13. Remove laying. Fix the camshaft from a provorachivaniye, holding it a wrench for vents between cams of the third and fourth cylinders and unscrew a bolt of fastening of a pulley of the camshaft.
14. Remove a pulley from the camshaft.
15. For removal of a pulley of a bent shaft on l engines 1,4 and 1,6, except the C16 NZ2 engine unscrew the lower bolts of fastening of the main back cover of a gear belt and insert two big screw-drivers behind a cover and remove a pulley of a bent shaft. Remove a segment spline from a bent shaft.
16. For unscrewing of a bolt of fastening of a pulley of a bent shaft on C16 NZ2 engines 1,8 and 2,0 it is necessary to record a bent shaft from a provorachivaniye for what the assistant has to include any transfer and press a brake. Using a stripper, remove a pulley from a bent shaft. Remove a segment spline and a persistent washer from a bent shaft.
17. For removal of a back main casing of a driving belt on C16 NZ2 engines 1,8 and 2,0 of l disconnect the electric socket from the VMT sensor and disconnect an electrical wiring from a casing. Unscrew two top and one lower bolts of fastening of a casing and remove a casing, passing it through a smaller cover on the water pump (see rice. Unscrewing of the lower bolt of fastening of a back main casing of a driving belt on the engine of 2,0 l, the Arrangement of the lower bolts of fastening of the main back casing of a driving belt on the engine 1,6 SV).
18. If necessary remove a smaller back casing of a belt from the water pump for what unscrew a bolt of fastening and, turning a casing remove it from a fastening flange on the pump (see rice. Unscrewing of a bolt of fastening of a casing of a belt to the water pump on the engine of 2,0 l).
