Removing
1. Depressurize the fuel system and disconnect the negative battery cable.
Upper manifold chamber
2. Drain the coolant.
3. Remove two screws (arrows) and remove the engine cover.
4. Remove the air filter.
5. Disconnect the wires and hoses from the throttle, disconnect the throttle cable.
6. Disconnect the tube of the recirculation system (arrow) exhaust gases from the chamber.
7. Remove the two camera brackets.
8. Remove the bolts (A) and twist the nuts (IN), securing the chamber to the lower intake manifold and remove the chamber.
Lower part of manifold
1. Disconnect the wires from the fuel injectors.
2. Disconnect the heater hose (A) and air hose (IN) from a collector disconnect a fuel hose from a fuel highway.
3. Remove bolts and tighten nuts (arrows), remove the lower section of the manifold - the numbers indicate the sequence of tightening the bolts and nuts.
