Removal
TU engine
1 Slacken the retaining clips (where fitted),
and disconnect the vacuum hose and
breather hose from the front of the air cleaner
housing-to-carburettor duct (see illustration).
2.1 On the TU engine disconnect the vacuum and breather hoses (arrowed) from
the front of the duct . . .
Where the crimped-type Peugeot hose clips are fitted, cut the clips and discard them; use standard worm-drive hose clips on refitting.
2 Slacken the retaining clips, then lift the duct off the top of the carburettor and air cleaner housing. Disconnect the air temperature control valve hose from the end of the duct, and remove the duct from the engine compartment (see illustrations). Recover the rubber sealing ring(s) from the top of the carburettor and/or air cleaner housing (as applicable).
2.2a . . . slacken the retaining clips . . .
2.2b . . . and remove the duct, disconnecting the air temperature control
valve hose (arrowed)
3 Disconnect the inlet duct from the front of the air cleaner housing, and remove the air cleaner housing from the engine compartment.
4 To remove the inlet duct assembly, undo the retaining bolts securing the duct to the left-hand wing valance, then release the fastener securing the rear of the duct to the cylinder head (see illustration). Disconnect the hot-air inlet hose from the exhaust manifold shroud, and remove the duct and hose assembly from the engine compartment.
XU engine
2.4 Undo the intake duct front bolt then release the rear fastener, and
remove the duct and hose assembly (TU engine)
5 Using an Allen key, unscrew the bolt securing the air inlet duct to the top of the carburettor. Loosen the clip and disconnect the duct (see illustration).
2.5 On the XU engine unscrew the bolt securing the air inlet duct, then
loosen the clip
6 Loosen the clip and disconnect the air inlet duct from the filter housing top cover.
7 Release the clips and remove the top cover from the air filter housing.
8 Remove the filter element from inside the lower housing.
9 Release the lower housing from the mounting rubbers then disconnect the inlet duct and hoses as applicable.
Refitting
10 Refitting is a reversal of the removal
procedure, noting the following points:
a) Examine the rubber sealing ring(s) for
signs of damage or deterioration, and if
necessary renew. Note that, on some
models, the carburettor seal is fitted with
an O-ring; this should also be renewed if
it is damaged.
b) Where applicable, ensure that the air cleaner housing locating peg is correctly engaged with its mounting on the top of the transmission (see illustration).
c) Prior to tightening the air cleaner-tocarburettor duct retaining clips, ensure that the duct is correctly seated on both the air cleaner housing and carburettor flanges.
