GENERAL INFORMATION

Prevention

At installation of the exhaust system use new laying and sealing rings.


Problem of the exhaust system is removal of the fulfilled gases in the atmosphere so that they even in the minimum quantity did not get to interior of the car, and also reduction of noise of the engine to low level. That the exhaust system could perform the functions, it has to be in good repair. The condition of the exhaust system exerts impact also on the engine capacity and fuel consumption.

Removal

The exhaust system installed at the plant consists of four parts which replacement can be made separately.

On models with the catalyst in a reception exhaust pipe the oxygen sensor is installed. The catalyst is installed in a forward part of the exhaust system.

Before replacement of separate parts of the exhaust system it is recommended to check a condition of all exhaust system as it is often more favorable to replace all exhaust system, than to make replacement it periodically in parts.
