GENERAL INFORMATION

Prevention

If the round air filter is installed, you watch the corresponding description in subsection 6.3.


Removal

Weakening of a collar of fastening of an air branch pipe to the air stream measuring instrument

Unscrewing of the screw of fastening of the resonator

Extraction of the resonator from under a wing arch

Removal of a branch pipe of the resonator

PERFORMANCE ORDER
1. Disconnect a hose with cooling liquid of a broad tank from a cover of the air filter and move it aside.
2. Weaken a collar and disconnect an air branch pipe from the air stream measuring instrument (see rice. Weakening of a collar of fastening of an air branch pipe to the air stream measuring instrument).
3. Remove a weight wire from the accumulator, then disconnect the electric socket from the air stream measuring instrument.
4. Disconnect two brackets of fixing on the left side of a cover of the air filter, then unscrew two screws on the right side of a cover of the air filter and uncover.
5. Take the filtering element from the case of the air filter.
6. Weaken nuts of fastening of hoses of heating.
7. Unscrew nuts, the fixing two rubber racks located from the lower party of a casing of the air filter.
8. On some models the resonator of the air coming to the engine for noise reduction is installed. The resonator is located under an arch of a wheel and connects a branch pipe to an air inlet pipe.
9. Before removal of a pipe of an air inlet remove the resonator. For this purpose tighten the emergency brake, then lift a forward part of the car and record on supports.
10. Unscrew screws and take a mudguard from under a wing arch.
11. Unscrew the screw, then disconnect the resonator from a branch pipe and take it from under a wing arch (see rice. Unscrewing of the screw of fastening of the resonator, Extraction of the resonator from under a wing arch).
12. If necessary remove an air inlet pipe, previously having disconnected a branch pipe from under a wing arch (see rice. Removal of a branch pipe of the resonator).
13. Turning and moving an air inlet pipe, release adjusting pins from the forward panel of a body. It is rather labor-consuming operation and for simplification of removal of a pipe of a vozdukhozaborna it is possible to remove a headlight.

Installation

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal. At ustan ке the filtering element the rubber flange has to be directed up.
