Prevention
You watch precautionary measures in subsection 6.3.1 before work.
Removal
| PERFORMANCE ORDER |
| 1. Disconnect a wire of the negative plug of the accumulator. |
| 2. Remove a casing of the air filter (see subsection 6.3.1.2). |
| 3. Squeeze fixing clips and disconnect connection sockets from a potentiometer of a butterfly valve, the additional valve of air supply, the sensor of an air stream and wires of an injector. |
| 4. Also disconnect the socket of connection of the heating element established between the case of a butterfly valve and an inlet collector. |
| 5. Release pressure from fuel system (see subsection 6.3.1.7). |
| 6. Then release fixing collars and disconnect a hose of supply of fuel and a hose of the return pipeline from the case of a butterfly valve. |
| 7. Disconnect an accelerator rope from a cam of a butterfly valve on the case of a butterfly valve, then turn off a lock-nut and an adjusting nut and get a rope braid from a fixing arm. |
| 8. On models with the automatic transmission also disconnect a rope of decrease in transfer. |
| 9. Release fixing collars, then, disconnect cooling system hoses behind the case of a butterfly valve and stop up openings of hoses. Make it quickly to minimize loss of cooling liquid. |
| 10. Remember or mark the provision of installation of all vacuum and ventilating hoses in order that it is correct to connect them at installation of the case of a butterfly valve, then, release fixing collars (where are established) and disconnect hoses from the case of a butterfly valve. |
| 11. Turn off and remove the fixing bolts fixing the case of a butterfly valve to an inlet collector and remove the case of a butterfly valve from the car. |
| 12. Remove a heating element. |
| 13. Stop up an opening of an inlet collector with a pure rag in order that dirt or foreign objects did not get to it. |
| 14. If it is necessary, after removal of the case of a butterfly valve turn off fixing screws and divide the top and lower sections. |

Installation
| PERFORMANCE ORDER |
| 1. Installation is carried out upside-down removals. |
| 2. At installation it is necessary to pay attention to the next moments. |
| 3. If it is necessary, check that the adjoining surfaces of the top and lower sections of the case of a butterfly valve were pure and dry, then, establish new laying and collect sections, having reliably tightened fixing screws. |
| 4. Before installation check that the adjoining surfaces of the case of a butterfly valve, an inlet collector and a heating element were pure and equal. |
| 5. Install the case of a butterfly valve and a heating element on an inlet collector. |
| 6. Diagonalno tighten all fixing bolts till the required moment of an inhaling of a stage 1, then, tighten them till the required moment of an inhaling of a stage 2. |
| 7. Check that all hoses were correctly established and if it is necessary, fix them by means of fixing collars. |
8. Upon completion of installation adjust an accelerator rope (see subsection
6.3.1.3). |
| 9. On models with the automatic transmission adjust a rope of a low gear (see subsection 9.2.4). |
