REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: Cylinder head gas-
ket.
aparts always to be replaced: cylinder head bolts.
1 - Cleaning the cylinder head
aApply SUPER CLEANER FOR JOINT FACES (see
Vehicle: Parts and consumables for the repair)
(04B, Consumables - Products) to the areas to be
cleaned.
aWait for approximately ten minutes.
aRemove the residue using a wooden spatula.
aFinish cleaning with a grey abrasive pad.

WARNING
Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
WARNING
Do not allow this product to dr ip onto the paint-
work.
Clean the cylinder head carefully to prevent for-
eign bodies from entering the oil supply and
return galleries.
Failure to follow this advice could lead to the
blocking of the various oil inlet galleries, which
would quickly result in engine damage.
WARNING
Protect the oilway so that foreign bodies do not
enter the oil pipes in the cylinder head.
Failure to follow this instruction could lead to the
blocking of the oilways, resulting in a rapid deteri-
oration of the camshaft.
Note:
The cylinder head bolts must not be lubricated
before being fitted.

2 - Checking the gasket face
aCheck the flatness of the cylinder head gasket face
(see Cylinder head: Check) .
3 - Optional additional operations
aWhen replacing the cylinder head, strip the cylinder
head (see Cylinder head: Stripping - Rebuilding) .
aIf necessary, carry out a complete check of the cylin-
der head (see Cylinder head: Check) .
II - REFITTING OPERATION FOR PART
CONCERNED
aBring the pistons to mid-stroke position to prevent
them from coming into contact with the valves during
the tightening of the cylinder head.
aCheck for the cylinder head centring dowels on the
cylinder block.
aFit a new cylinder head gasket onto the cylinder
block, positioning the marking (8) on the oil filter
side.
