Removing
1. The general connection diagram of the components of the intake tract of the air supply system is shown in resist. illustrations. Basically, the fastening of pipelines and sleeves is carried out by means of clamps of various types. In some cases, bolted connections are used for this purpose.
6.1a Intake air path (on the example of the Z18XE engine): 1. Air cleaner; 2. Air mass measurement sensor; 3. Intake air duct; 4. Hose of the crankcase ventilation system; 5. Front intake duct; 6. Connecting sleeve
6.1b Connection diagram of the components of the intake air path of a turbocharged engine (on the example of the Z19DTH engine): 1. Air cleaner housing; 2. Intake air duct; 3. Boost sleeve; 4. Throttle pipe; 5, 7, 10, 11. Boost hoses; 6. Turbocharger with exhaust manifold; 8. Boost pipe; 9. Air cooler (intercooler); 12. Resonator; 13. Drainage tube; 14. Connecting sleeve; 15. The lower part of the air filter housing; 16. Air mass measurement sensor
2. The most important element of the air supply system is the air cleaner. When performing maintenance work, it is enough to remove only the top cover, but when performing many repairs and replacing other elements of the engine compartment, it is necessary to dismantle the entire air cleaner assembly.
3. This Section discusses in detail the procedure for removing the air cleaner engine Z18XE. On other engines, this operation is carried out similarly.
4. Having pressed a clamp, disunite a socket of electroconducting of the gauge of measurement of mass of air. Release the wiring harness by cutting the holders, if necessary, mark their position for subsequent installation of new ones.
5. Disconnect the hose (see illustration 6.1a) crankcase ventilation system, loosen the mounting clamps and remove the intake manifold. Release the air cleaner from the holders, disconnect the connecting sleeve and remove the air cleaner housing from the engine compartment
6. On Y20DTH / Y22DTR engines, when removing the air cleaner, additionally pull up the holder (see resist. illustration) solenoid valve and atmospheric pressure sensor.
