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).
