Both sides of the
Throttle Body and the EGI valve are connected to the EGR tube which also goes into the intake manifold plenum. Before you take out the upper tube, you need to remove the negative
Battery Cable, then remove the air inlet tube and resonator next, finishing with the repositioning of the throttle cable bracket. Then, remove the screws that attach the EGR tube to the manifold plenum and the
EGR Valve and gently take out the EGR upper tube, so the silicone rubber seals do not enter the intake manifold. Be sure to clean the gaskets on the EGR valve, as dirt on them could result in leaking and both an uneven idle and declining manifold vacuum. Check the silicone seals on the EGR tube's manifold end, then safely insert the upper tube into position. Connect a new gasket between the EGR valve and the EGR tube, using bolts and tighten the EGR tube to the manifold with 11 Nm (95 in. lbs.). Fix back the throttle cable bracket, air inlet tube and resonator and link up the negative battery cable as well. To remove the lower tube, detach the negative battery cable, disconnect the air inlet tube, take off the resonator, bracket and remove the screws from the EGR mount at its valve and the
Exhaust Manifold. While installing, add a gasket between the EGR valve and tube, hold it in place, then put gaskets between the exhaust manifold and tube. Twist the bolts holding the EGR tube to the EGR valve to 11 Nm and twist the EGR tube to exhaust manifold bolts to 31 Nm torque. After that, replace the air inlet tube, resonator and bracket, plus connect the negative battery cable.
