GENERAL INFORMATION, Precautions when working with electrical equipment.
Dismantling
1. Put the car on a lift.
2. Disconnect "negative" battery terminal.
3. Remove the exhaust system.
EXHAUST MANIFOLD AND EXHAUST GAS SYSTEM: V-8 engine, REPAIRS, Exhaust system and system components suspension.
4. Remove the downstream heated oxygen sensors (HO2S) from the exhaust system and discard the sealing washers.
5. Using tool LRT-99-027, cut the pipe at the location indicated by the indentation.
Assembly
1. Install on oxygen sensors (HO2S) new sealing washers and lubricate the threads on the sensors with anti-seize lubricant. Screw in and tighten the sensors. Tightening torque 50 Nm.
CAUTION: Be careful not to get any anti-seize lubricant on the active part of the oxygen sensor (HO2S).
2. Wipe down pipe flange and mating surfaces.
3. Install downpipe, align flanges, fit nuts and do not tighten yet.
4. Wipe the intake and intermediate pipes, put on the connecting sleeve.
5. Reinstall the exhaust system.
EXHAUST MANIFOLD AND EXHAUST GAS SYSTEM: V-8 engine, REPAIRS, Exhaust system and system components suspension.
6. Center the coupling sleeve, align the intermediate tube with the downpipes and tighten the sleeve clamp nuts. Tightening torque 48 Nm.
7. Check up correctness of provision of system of release of the fulfilled gases.
8. Attach "negative" battery terminal.
