FUEL HIGHWAY AND ATOMIZERS
Removal and installation
| PERFORMANCE ORDER
|
| 1. Remove pressure in fuel system. Remove a wire of weight from the accumulator. |
| 2. Remove the top section of an inlet collector. |
| 3. Disconnect electric sockets from four fuel atomizers and remove a plait of wires from a fuel highway. |
| 4. Unscrew connecting nuts and disconnect fuel hoses from a fuel highway. |
| 5. Unscrew three bolts and remove a fuel highway together with atomizers from an inlet collector. Remove the bottom sealing rings from fuel atomizers. |
| 6. Release скобы fastenings and take fuel atomizers from a fuel highway. Remove the top sealing rings from fuel atomizers. |
| 7. Installation is made in sequence, return to removal. Thus on fuel atomizers it is necessary to establish new sealing rings. |
|
PRESSURE REGULATOR
Removal and installation
| PERFORMANCE ORDER
|
| 1. Remove pressure in fuel system and remove a wire of weight from the accumulator. |
|
|
2. For access improvement to a fuel highway remove an arm of a plait of wires from an inlet collector. On engines DOCH of 1,6 l the pressure regulator settles down on the left forward end of a fuel highway. |
| 3. Keeping a regulator a wrench, unscrew a connecting nut of a hose of giving of fuel. Disconnect a hose of giving of fuel and a vacuum hose from a regulator. |
| 4. Unscrew bolts and remove an arm of electric wires from a fuel highway. |
| 5. Remove a regulator from an end face of a fuel highway together with a sealing ring. |
| 6. Installation is made in sequence, return to removal. Thus it is necessary to use a new sealing ring. |
|
THE ENGINE OF MANAGEMENT OF IDLING TURNS
Removal and installation
| PERFORMANCE ORDER
|
| 1. For access to the engine of management of idling turns remove the case of throttles. |
|
|
2. Unscrew screws (are specified by arrows) and remove the engine of management of idling turns together with sealing rings. |
| |
3. Installation is made in sequence, return to removal. Before engine installation check up, that the end face плунжера left the case of the engine no more than on 33 mm. |
|
THROTTLE POTENTIOMETER
Removal and installation
| PERFORMANCE ORDER
|
| 1. Remove the case of throttles. |
|
|
2. Unscrew screws (are specified by arrows) and remove a potentiometer from a throttle. |
| 3. At potentiometer installation, check up, that it was correctly combined with an axis of throttles. |
|
THE GAUGE OF TEMPERATURE OF THE COOLING LIQUID
The gauge of temperature of a cooling liquid is screwed in in a thermostat casing.
THE GAUGE OF TEMPERATURE OF AIR ARRIVING IN THE ENGINE
The temperature gauge is established in the inlet channel which connects a casing of the air filter to an inlet collector.
Removal and installation
| PERFORMANCE ORDER
|
| 1. Switch off ignition and disconnect an electric socket from the gauge. |
| 2. Take the gauge and remove a sealing ring from the inlet channel. |
| 3. Installation is made in sequence, return to removal. |
|
THE GAUGE OF ABSOLUTE PRESSURE IN THE INLET COLLECTOR
|
|
The gauge of absolute pressure in an inlet collector is established on a partition of a motor compartment on the left side from an inlet collector. |
Removal and installation
| PERFORMANCE ORDER
|
| 1. Switch off ignition and remove an electric socket and a vacuum hose from the gauge. Remove the gauge. |
| 2. Installation is made in sequence, return to removal. |
|
THE GAUGE OF THE CRANKED SHAFT
The gauge is established on a back part of the block of cylinders and is accessible from below the car.
Removal and installation
| PERFORMANCE ORDER
|
| 1. Lift a forward part of the car and fix on supports. |
| 2. Take electric conducting of the gauge from скоб fastenings and disconnect an electric socket of the gauge. |
| 3. Unscrew a bolt and remove the gauge. |
| 4. Installation is made in sequence, return to removal. |
| 5. Using an edge probeа, check up, that the backlash between an end face of the gauge and teeths of a pulley of a cranked shaft made 1±0,7 mm. |
|
THE CAMSHAFT GAUGE
| PERFORMANCE ORDER
|
| 1. Remove the top casing of a gear belt. |
| 2. Release electroconducting of the gauge from скоб fastenings and disconnect an electric socket. |
|
|
3. Unscrew bolts and remove the gauge from a head of the block of cylinders. |
| 4. Installation is made in sequence, return to removal. |
|
THE DETONATION GAUGE
The detonation gauge is established on a back part of the block of cylinders and is accessible from below the car.
Removal and installation
| PERFORMANCE ORDER
|
| 1. Lift a forward part of the car and fix on supports. |
| 2. Disconnect the electric socket of the gauge located on wires of the gauge. |
| 3. Unscrew a bolt and remove the gauge from the engine. |
| 4. Check up, interfaced surfaces of the gauge and the block of cylinders pure and dry, establish the gauge, fix a bolt and connect an electric socket. |
|
THE ELECTRONIC CONTROL DEVICE
Block ECU is located under a water reflector before a windscreen.
Removal and installation
| PERFORMANCE ORDER
|
| 1. Remove a wire of weight from the accumulator. Remove screen wiper levers. |
| 2. Remove the top consolidation from a partition of a motor compartment and remove a water reflector. |
| 3. Unscrew nuts and remove a protective casing of block ECU. |
| 4. Disconnect electric sockets, unscrew nuts and remove block ECU. |
| 5. Installation is made in sequence, return to removal. |
|
THE RELAY OF THE FUEL PUMP
The relay of the fuel pump is located in a motor compartment in the relay block.
Removal and installation
| PERFORMANCE ORDER
|
| 1. Uncover the block of the relay and remove the relay of the fuel pump which is painted in violet colour. |
