Intake manifold (engines 2.0 l / 2.4 l).
1 - intake manifold absolute pressure sensor, 2 - intake manifold reservoir, 3 - intake manifold, 4 - throttle body, 5 - idle speed control servo, 6 - power transistor, 7 - gasket, 8 - injector, 9 - fuel manifold, 10 - gasket, 11 - fuel pressure regulator.
Withdrawal
1. Disconnect the air intake hose from the throttle body.
2. Disconnect the accelerator pedal cable.
3. Disconnect the coolant hose from the throttle body.
4. Disconnect a hose of system of compulsory ventilation of a crankcase and a vacuum hose of the amplifier of brakes.
5. Disconnect the vacuum hoses.
6. Remove the protective cover of the nozzles.
7. Before disconnecting the high pressure fuel hose from the fuel manifold, bleed any residual pressure from the high pressure fuel lines to prevent fuel splashing.
8. Disconnect the fuel injector harness connector.
9. Remove a fuel collector together with atomizers.
Note: Be careful not to drop the injectors when removing the fuel manifold.
10. Remove the intake manifold bracket.
11. Remove the intake manifold.
Installation
1. Replace the intake manifold gasket with a new one and reinstall the intake manifold.
Torque:
- bolts: 15-20 Nm
- nuts: 30-42 Nm
2. Install the fuel manifold with injectors on the intake manifold.
Attention: be careful not to allow contact (blows) nozzles with the edges of the holes for the nozzles in the intake manifold.
3. Install the intake manifold support bracket.
4. Connect the fuel injector harness connector. Install the nozzle cover.
5. Connect the high pressure fuel hose.
6. Connect the vacuum hoses.
7. Connect a hose of system of compulsory ventilation of a crankcase and a vacuum hose of the amplifier of brakes.
8. Connect the air inlet hose to the throttle body.
9. Connect the accelerator pedal cable.
Examination
1. Check all parts, including air hoses, for damage, cracks and deformation, if any, replace the part. Clean parts if necessary.
Attention: when cleaning, do not allow foreign particles to enter the openings of the channels of the engine cooling jacket or the channels of the oil system.
2. Check the condition of the intake manifold gasket.
3. Check for clogging of the openings of the vacuum outlet fittings, coolant passage channels, channels of the forced crankcase ventilation system.
4. Using a straightedge and a set of feelers, measure the flatness of the mating surface of the cylinder head, as well as the mating surfaces of the receiver and intake manifold.
Non-flatness of the mating surface:
- Rated: less than 0.15 mm
- Maximum allowable: 0.20 mm
