Exhaust system — removal and installation (Opel Corsa B)

Removal

Each section of the system can be dismantled separately. It is also possible to remove the entire exhaust tract as a whole. Even if only a separate section needs to be replaced, it is easier to dismantle it after the entire assembly has been removed.

1. Jack up the front of the car and place it on supports (with the appropriate equipment of the site, it is possible to drive a car onto an overpass or inspection pit). If equipped, remove the crankcase guard.

2. Spray all components of the exhaust system with a rust dissolving agent and wait until the rust dissolves.

3. Loosen the main muffler mounting clamp.

4. Remove the muffler from the rubber holder and disconnect it from the central pipe.

5. Disconnect the inlet pipe from the exhaust manifold.

7. Remove the exhaust system from the rubber holders.

The catalytic converter is sensitive to impact, do not hit or drop it.

Installation

1. Assemble the front part of the exhaust system without tightening the bolts. Be sure to use new bolts, seals and damping rings. The mating surfaces should be cleaned beforehand.

2. It is recommended to lubricate all bolts with high-temperature grease, such as Liqui Moly LN-508-ASC, which will facilitate subsequent disassembly of the connections.

3. Ask an assistant to lift the exhaust system or support it with wooden blocks.

4. Hang the central muffler on the rubber holders.

5. Install the exhaust pipe onto the exhaust manifold with a new seal and secure with new bolts, but do not tighten them.

6. On a diesel engine, secure the exhaust pipe to the holder.

7. Place the main muffler on the intake pipe from behind. First, slide the clamp onto the muffler connecting pipe. On cars produced since 09.1996, the clamp is welded to the main muffler pipe.

8. Hang the main muffler on the rubber holder.

9. Before tightening the threaded connections, align the exhaust system with the contour of the vehicle's underbody so that the system is not subject to mechanical stress. Make sure that there is sufficient space between the system elements and the body and that the rubber holders are evenly loaded.

10. Tighten the bolts to the required torque.

11. Lower the car to the ground.
