GENERAL INFORMATION

Prevention

If the round air filter is established, look the corresponding description in subsection 6.3.


Removal

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

Unscrewing of the screw of fastening of the resonator

Resonator extraction 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 a measuring instrument of a stream of air (see fig. Weakening of a collar of fastening of an air branch pipe to a measuring instrument of a stream of air).
3. Remove a weight wire from the accumulator, then disconnect the electric socket from a measuring instrument of a stream of air.
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 from the case of the air filter filtering element.
6. Weaken nuts of fastening of hoses of heating.
7. Unscrew the nuts, the fixing two rubber racks located from the bottom party of a casing of the air filter.
8. On some models the resonator of the air arriving in the engine for reduction of noise is established. The resonator is located under an arch of a wheel and incorporates 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 hand brake, then lift a forward part of the car and fix 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 fig. Unscrewing of the screw of fastening of the resonator, resonator Extraction 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 fig. 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 воздухозаборни it is possible to remove a headlight.

Installation

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