Removal and installation

Models with the carburetor engine of 4.2 l

Removal

Components of system of release

1 — a reception pipe
2 — nuts
3 — laying
4 — a flange
5 — the thermofilter
6 — a collar
7 — bolts
8 — rubber pillows
9 — washers
10 — assembly of an exhaust pipe
11 — intermediate section with the exhaust silencer

PERFORMANCE ORDER

To Poddomkratta the car also establish it on props.

Before starting an otdavaniye of any fixture of system of production of the fulfilled gases impregnate it with suitable getting structure or the rust converter.

Give nuts and bolts of fastening of a flange of an exhaust pipe of system to intermediate section with the exhaust silencer. Give a nut of a support of an exhaust pipe, remove washers, rubber pillows and a bolt and take an exhaust pipe from under the car. Give nuts and bolts of fastening of intermediate section with the exhaust silencer to a reception pipe of system of production of the fulfilled gases. Give fixture of arms подвеса to intermediate section with the exhaust silencer, remove washers rubber pillows and take assembly from under the car.

In case of problems with a detachment of sections of system from each other, they can be cut off by a hacksaw or truborezy with the subsequent replacement.

At an otdavaniye of the "become attached" fixture be careful not to damage the floor panel, fuel and brake lines or chassis electroconducting.

Give nuts of fastening of a reception pipe to a final collector. Give a nut back подвеса a reception pipe, remove a washer, rubber pillows, a bolt and take assembly from under the car.

Installation

Installation is made upside-down.

PERFORMANCE ORDER

Smooth out interfaced surfaces of all flange connections, surely replace laying. At first establish all sections of system on the car, without tightening finally their fixture. Check correctness of an arrangement of components, make sure that they do not adjoin to the bottom of the car and chassis and suspension bracket elements. In case of need correct the provision of sections. Tighten fixture, since flange connection of a reception pipe with a final collector. Start the engine and check release system on existence of signs of leakages of the fulfilled gases. Eliminate the reason of the revealed leaks, then lower the car on the earth.

Models with the carburetor engine of 3.0 l

Procedures of removal and installation of components of system of production of the fulfilled gases are completely similar 4.2 l described for carburetor engines.


1 — the thermofilter 2 — bolts 3 — nuts 4 — a collar 5 — laying 6 — a reception pipe	7 — rubber pillows 8 — washers 9 — assembly of an exhaust pipe 10 — an arm 11 — intermediate section with the exhaust silencer

Models with the engine of 4.2 l of EFI (since 1992 вып.)

The design of system of production of the fulfilled gases of models of 4.2 l of EFI generally differs from presented on illustrations, except for installation between a reception pipe and the exhaust silencer of the catalytic converter a little.

The catalytic converter is a component of system of decrease in toxicity of the fulfilled gases and represents the ceramic core placed in a metal casing covered with a layer of platinum, палладиума and rhodium. Passing through the converter, hydrocarbonic connections containing in fulfilled gases, oxides of nitrogen (NOH) and carbon monooxide (WITH) will be transformed as a result of chemical reactions to carbon dioxide, nitrogen and water.

In normal conditions the catalytic converter does not need regular service or replacement. However, it can be put out of action or irreversible is polluted as a result of influence of excessive temperatures of the fulfilled gases, hit of crude fuel or when using etilirovanny fuel (with the high content of lead). In order to avoid casual filling by etilirovanny fuel the fuel tank of models of 4.2 l of EFI is equipped with a jellied mouth of smaller diameter which besides is equipped with a podpruzhinenny door trap. The ceramic core also can be damaged as a result of blows and strong pushes. At an overheat or a zasvintsovyvaniye of the core there is a violation of its passableness that conducts to decrease in section of a final path through passage, increase of resistance to production of gases and decrease, thereby, overall performance of the engine.
In the engine of the car equipped with the catalytic converter it is necessary to fill in oil with the lowered content of phosphorus.

In order to avoid damage of the catalytic converter it is necessary to observe rules:

Do not fill the car with etilirovanny fuel; Do not get the car with a point and do not tow it; Try not to allow long operation of the engine on single turns; Do not use the car at emergence of admissions of ignition; Avoid complete production of fuel.
