Removal and installation of the inlet pipeline
|
|
Start procedure performance only after final cooling of the power unit. |
Two half of the inlet pipeline and its components
On engines 2UZ-FE the inlet pipeline, two-piece is established. The top part (the Toyota company calls it the inlet chamber) contains the throttle case. The lower part is actually inlet pipeline and fastens to a head of cylinders (address to an illustration above). In the lower part of the pipeline fuel nozzles and the highway are established.
|
|
At the address with easy aluminum parts be accurate, they are easy for damaging. Pay attention that in this engine the starter fastens to the bottom half of the inlet pipeline. The starter is turned back, entering into gearing with a flywheel above. |
|
|
After ignition switching off in fuel system there is a residual pressure. Before a detachment of fuel highways pressure is necessary for removing not to be traumatized.
|
Removal
|
|
|
1. Remove pressure in fuel system (see. Head of the Power supply system and production of the fulfilled gases).
2. Merge cooling liquid.
3. Disconnect an accelerator cable, a cable of a throttle of AT (at the corresponding complete set) and a cable темпостата (at the corresponding complete set) from the throttle case.
4. Disconnect fuel highways.
5. Disconnect from the inlet pipeline the following sockets:
- Sensor of provision of a butterfly valve (TPS)
- Socket of the sensor of provision of a pedal of gas
- Socket of the motor of management of a butterfly valve
- I will corrode managements of a purge of a coal adsorber of EVAP
- Eight sockets of fuel nozzles (on the first hang a label)
- Sockets of the sensor of the index of temperature of cooling liquid and the sensor of the indicator of temperature of cooling liquid
- Eight (on the first hang a label) sockets of coils of ignition
- Two sockets lambda probes
6. Hang labels and disconnect from the inlet pipeline the following hoses:
- Vacuum hose from a regulator of pressure of fuel
- PCV hose from the PCV valve on the left head of cylinders
- Three hoses of a purge of a coal adsorber of EVAP
- Vacuum hoses of GUR
- If the car is not equipped by the hydraulic booster of brakes, disconnect a vacuum hose of the vacuum amplifier
7. Disconnect an accelerator cable from the case of a throttle and remove three clamps.
8. Disconnect roundabout a hose of system of cooling from the forward roundabout union.
9. Disconnect fastenings of conducting of the engine where it is attached to the right fuel highway.
10. Unscrew three bolts of fastening of protection of conducting of the engine from the back roundabout union of system of cooling on both heads of cylinders.
11. Disconnect from both heads of cylinders of the tire "weights".
12. Remove the diagnostic DLC1 socket from an arm of a cover of the case of a throttle and remove an arm from the inlet pipeline.
13. Give two nuts and remove an arm of a cable of an accelerator from the inlet pipeline.
14. Unscrew nuts and bolts and remove the inlet pipeline entirely together with fuel highways. |

Installation
|
|
1. Scratch out from interfaced surfaces of the pipeline and heads of cylinders all traces of hermetic and a material of old laying, then wipe surfaces the rags moistened in acetone. Check planeness of interfaced surfaces a steel ruler and a set flat щупов. The admissible curvature of the plane makes 0.15 mm. At excess of admissible value of a detail are subject to replacement.
2. Check new laying. Factory laying has a label made white paint, meaning "top", Accurately combine openings of channels and laying. Having established two new laying, accurately lower the pipeline into place.
3. Wrap bolts and fastening nuts with effort of 18 Nanometers.
4. Installation of the remained components is made as it should be, the return to an order of their dismantle.
5. Fill cooling system. Start the engine and check it on existence of signs of development of leakages of the fuel, cooling liquid and depression losses. |
