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.
aComplete the cleaning operation using a grey abra-
sive pad.
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.
aRefit:
-a new cylinder head gasket,
-the cylinder head.
Cylinder head tightening procedure
aRefit the new cylinder head bolts.
aFit the cylinder head bolts, without tightening them. 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 drip onto the paint-
work.
Clean the cylinder head carefully to avoid any
foreign bodies entering the oil return and supply
pipes.
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.
WARNING
No regrinding of the cylinder head is permitted.
WARNING
In order to ensure that the bolts are correctly
tightened, use a syringe to remove any oil which
may be in the cylinder head mounting holes.
