A: Emptying the exhaust gas recirculation (EGR) pipe requires unfastening the pipe bracket holder and untightening fittings at both egr pipe ends before pipe extraction. To install the egr pipe correctly position it in place before slowly hand starting the pipe fittings. Safely align both egr pipe fittings on their adaptors for the Exhaust Manifold and Intake Manifold before tightening them to 30 n.m (22 lb ft) and 25 n.m (18 lb ft) torque settings respectively. The last step involves installing the egr pipe bracket retaining fastener at 25 n.m torque (18 lb ft torque).
