Removal
Caution! For dismantling, you will need the special RENAULT Tav. 1233-01 tool for lowering the supporting frame. 1 Disconnect the ground (-) cable terminal from the battery.
Warning! This will erase some data from the memory of the storage devices, for example, the access code preventing unauthorized use of the radio receiver will be erased. Before disconnecting the battery, please read the instructions in the chapter "Removal and installation the battery".
2. Place the vehicle on jack stands.
3. Secure the steering wheel. You can use a mechanical clamp used as an anti-theft device, or secure the steering wheel on both sides with straps.
4. Remove the air filter.
5. Unscrew the bolts securing the catalytic converter connecting flange to the exhaust manifold, acting from the engine compartment side.
6. Fasten with bolts instead of the supporting frame mounting bolts 1 special device Tav. 1233-01. Fasten at points A and B (see illustration). In this case, first unscrew one frame mounting bolt and screw in the device mounting bolt, and then unscrew and screw in the second one.
7.6 Fasten with bolts instead of the supporting frame mounting bolts 1 special device Tav. 1233-01
7. Unscrew the clamping bolt 1 of the crosspiece 2 on the steering column by unscrewing the nut (see illustration).
7.7 Unscrew the clamping bolt 1 of the crosspiece 2 on the steering column by unscrewing the nut
8. Remove the stabilizer support bar, refer to the corresponding chapter.
9. If a second lambda probe is installed behind the catalytic converter, disconnect the probe power supply wire.
10. Lower the supporting frame 1 by 20 mm first at point A by turning the nut (see illustration 7.6). After this, in the same way, lower the frame by 40 mm at point B.
11. Remove the mounting clamp between the catalytic converter and the additional muffler.
12. Unscrew the bolts securing the catalytic converter to the flange on the exhaust manifold and remove the catalytic converter.
Installation
Before installing the catalytic converter, inspect all heat-reflecting shields. If they are damaged, remove the shields and replace them with new ones.
13. Place the catalytic converter back on the exhaust manifold, replacing the old sealing gasket with a new one. Tighten the catalytic converter mounting bolts by hand.
14. Install a new mounting clamp between the catalytic converter and the additional muffler. Tighten the clamp mounting nut by hand.
15. Straighten the exhaust pipes, if necessary, so that they stand without tension.

16. Tighten the mounting clamp nut.
17. Tighten the nuts of the bolts securing the connecting flange to the exhaust manifold with a force of 20 Nm.
18. Connect, if necessary, the power wire of the second lambda probe.
19. Replace the stabilizer support bar, see the relevant chapter.
20. Connect the steering column to the steering gear by installing the crosspiece clamp bolt in place. The tightening torque of the bolt nut is 30 Nm.
21. Raise the supporting frame by turning the nuts of the special device. Then first unscrew the rear mounting bolt of the special device and screw in the frame mounting bolt, and then the front one.
Tightening torques for frame mounting bolts:
- Bolt M12 (rear) = 105 Nm
- Bolt M10 (front) = 62 Nm
22. Remove the device that secured the steering wheel.
23. Lower the car onto its wheels.
24. Connect the negative (-) battery terminal to the negative battery terminal.
25. Enter the security code into the radio receiver if necessary and set the clock.
