Removal

1. Raise vehicle on ramp.
2. Remove rear exhaust silencer (refer to Workshop Manual procedure 09.00.KA Silencer and Bypass Valve Assembly - Remove for Access and Refit).
3. Disconnect multiplugs (x2), HEGO sensors.
4. Secure sufficient lengths of string to HEGO sensor multiplugs for assembly purposes.
5. Loosen LH and RH clamp nuts, catalysts to centre pipes.
6. With assistance, manoeuvre exhaust centre pipe assembly rearwards to release from catalysts.
7. Remove nuts (x3), catalyst to exhaust manifold.
8. Release and support weight of LH catalyst from exhaust manifold.
9. Manoeuvre HEGO sensor leads and remove cable tie. Release HEGO sensor leads from behind heat shield. Remove string from HEGO multiplugs.
10. Remove catalyst assembly.
11. Remove and discard gasket.
12. Remove HEGO sensors from catalyst.

Installation

1. Clean catalyst, mating joint faces and HEGO sensors.
2. Install and tighten HEGO sensor to catalyst.
3. Apply proprietary exhaust sealant around clamp joints.
4. Install new gasket to exhaust manifold.
5. Position catalyst, secure string (x2) to HEGO multiplugs, feed sensor leads behind heat shield. Install catalyst to exhaust manifold.
6. Instal land tighten nuts (x3), catalyst to exhaust manifold.
7. Align centre pipe assembly to catalyst, tighten clamp nuts to.
8. Remove string (x2), connect multiplugs (x2), HEGO sensors.
9. Install rear exhaust silencer (refer to Workshop Manual procedure 09.00.KA Silencer and Bypass Valve Assembly - Remove for Access and Refit).
10. Lower vehicle on ramp.
