tightened, refit the five smaller (M8 x 1.25)
bolts adjacent to the line of the spark plug
holes and tighten them to their specified
torque wrench setting (photo).
123 Reconnect the associated fittings to the
cylinder head in the reverse order of removal.
Ensure that the mating faces of the exhaust
manifold-to-downpipe are clean and fit a new
gasket when reconnecting.

Cylinder head
(1372 cc Turbo ie engine)
- removal and refitting
#
126 Proceed as described in paragraphs 102
to 125 above for the non-Turbo model, but
note the following differences.
127 The cylinder head cannot be removed
and refitted with the manifolds and
turbocharger fitted. It is therefore first
necessary to detach and remove the inlet
manifold, then the turbocharger and the
exhaust manifold as described in Section 9.
128 The ignition distributor is mounted on the
side of the engine, not the rear end of the
cylinder head as on the “ie” engine. It is
therefore only necessary to disconnect the HT
leads from the spark plugs.
Cylinder head - inspection
and renovation ¢
Note: Refer to a dealer for advice before
attempting to carry out valve grinding or seat
recutting operations. These operations may
not be possible for the DIY mechanic due to
the fitment of hardened valve seats for use
with unleaded petrol.
129 Use a straight-edge to check the cylinder
head gasket surface for distortion. If it
exceeds the specified tolerance, it must be
resurfaced by a FIAT dealer or automotive
engineer.
130 Refer to Section 39 in Chapter 1 for the
general details on dismantling and renovating
operations on the cylinder head but note that
there is a spring seat and a flat washer fitted
between the cylinder head and the valve
springs (photos).
