Exhaust system - inspection, removal and refitting

Fuel and exhaust systems - K-Jetronic fuel injection - 8 valve engines / Exhaust system - inspection, removal and refitting

Without catalytic converter 1 Refer to Section 20 in Part A of this Chapter whilst noting that all models manufactured after August 1985 are fitted with a manifold/ downpipe flange incorporating a gasket instead of spring clips.

With catalytic converter 2 The catalytic converter (where fitted) is positioned at the forward end of the exhaust system and comprises a steel casing over a ceramic body. It incorporates a longitudinal multi-passage honeycomb unit, which is coated with a layer of platinum or rhodium.

3 Removal is simply a matter of releasing the flange or socket type couplings and separating the components (see illustration).

25.3 Typical exhaust system with catalyst

1 Cap
2 CO measuring pipe
3 Exhaust manifold
4 Spring clips
5 Exhaust front pipe
6 Heat shield
7 Catalytic converter
8 Intermediate pipe
9 Centre silencer
10 Rear silencer

4 Note that the catalytic converter is fragile.

Do not strike it with tools and take care not to allow it to contact jacks or lifting gear.

5 Always use new coupling seals and gaskets during reassembly.
