Removing-refitting

NOTE The butterfly casing and the air flow meter form a single assembly.

Removing-refitting

Proceed with the removal of the butterfly casing as follows:

• - remove the inlet hose from the butterfly casing, loosening the retaining bands;
• - remove the accelerator cable (1), completely undoing the connector on the adjustment bracket and releasing the cable from the lever on the butterfly casing;
• - disconnect the electrical connectors from the butterfly position sensor (2), the idle speed adjustment solenoid valve (3) and the air flow meter (4);
• - remove both connecting pipes from the PCV valve;
• - undo the four bolts (arrow) fixing the butterfly casing to the inlet manifold;
• - remove the coolant connecting pipes from the inlet and outlet pipes, sealing them appropriately.

NOTE Do not remove the layer (5) of molybdenum disulphide applied to the edge of the butterfly.
