When removing EGR upper tube assembly being
careful not to drop the silicone rubber seals in the
intake manifold. Clean gasket surfaces on the EGR
valve. Note that any loose dirt can lodge between the
pintle and the seat and cause valve leakage that will
give a rough idle and depressed manifold vacuum.
(6) Remove EGR tube.
INSTALLATION
(1) Install rubber silicone seals on intake manifold
end of EGR tube (Fig. 8), being careful to be sure sil-
icone rubber seals is correctly installed and undam-
aged.
(2) Using a new gasket, loosely install the EGR
tube into the intake manifold and loosely install EGR
tube to EGR valve.
(3) Tighten the EGR tube to EGR valve screws to
11 N·m (95 in. lbs.) torque.
(4) Install clips for the EGR tube to intake mani-
fold plenum (Fig. 9).
(5) Install transmission to throttle body bracket.
(6) Install air inlet tube and resonator.
(7) Connect negative battery cable.
