GENERAL INFORMATION

1.9 LITRES ENGINES


Prevention

Inlet and final collectors are established on the same laying. Therefore it is recommended to remove at the same time both collectors that it was possible to replace laying.


Removal

PERFORMANCE ORDER
1. Disconnect the negative plug of the accumulator.
2. Remove the system of pipes of an air inlet from the top part of the engine attached to an inlet collector.
3. Remove a vacuum hose, then unscrew two bolts of fastening of a diaphragm of management to a collector. Move assembly of a diaphragm aside.
4. Lift a forward part of the car and record on supports. Remove a mudguard from under the engine.
5. If the system of inlet pipes was not removed, disconnect an entrance opening from a turbocharger exit. Close a turbocharger opening a pure rag.
6. Unscrew two bolts fixing the EGR valve to the top part of a final collector.
7. Unscrew bolts of fastening of an inlet collector. Weaken, but do not unscrew completely central bolt of fastening of a collector which is located in a collector groove.
8. Remove a collector from a head of the block of cylinders.

Installation

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal.
2. It is necessary to consider the next moments:
     – replace laying;
     – tighten all bolts the required moment;
