5.2.3. Air filter and air inlet channels



1. Weaken collars and remove the inlet channel from the case of the air filter.
2. On engines 1.9 liters disconnect an accelerator cable from a cover of the air filter. On engines 2.1 liters remove a hose of cooling liquid and an oil separator from a filter cover.
3. Unscrew screws of fastening of a cover of the air filter. Lift a cover and take the filtering element.
4. Remove the case of the air filter up in order that it was possible to disconnect all lower elements. On some models it is necessary to disconnect a small plastic element of fastening (it is specified by an arrow), the fixing case to the lower tube of an air inlet.
5. To pick up the air inlet phone, unscrew bolts of a suspension bracket of the case of the air filter and remove a suspension bracket. Release other end of a tube of an air inlet and remove it.


Inlet air channels are the difficult system consisting of the flexible hoses and rigid channels connecting the air filter, the refrigerator and a turbocharger.

Inlet channels are located in the top and back part of the engine, and on the 2.1 liters engines from a reverse side of the engine between the block of cylinders and the pallet. For removal of tubes from a reverse side of the engine it is necessary to lift a forward part of the car.
1. To remove an inlet pipe or the channel it is necessary to weaken collars on the ends of a pipe and to unscrew bolts of fastening of a pipe to an arm. On the 2.1 liters engines for removal of a forward air pipe it is necessary to switch-off the electric socket of the sensor of temperature of the soaked-up air.
2. After weakening of collars remove the end of a pipe from the union.


Installation is made in the sequence, the return to removal.
