Cleaning and anti-corrosion treat-
ment of engine compartment
The engine compartment and the out-
side surface of the power unit are given
anti-corrosion treatment at the factory.
If the engine compartment is cleaned at
any time with grease removing solu-
tions'* or if one has the engine washed,
the anti-corrosion compound is nearly
always removed as well. It is therefore
essential to ask for durable preservation
of all surfaces, seams, joints and compo-
nents in the engine compartment to be
carried out. This applies also when corro-
sion protected parts are renewed.
Every V.A.G dealer has stocks of the
cleaning and preservation solutions re-
commended by the factory for this pur-
pose and has the equipment necessary
to apply them.
The underside of the vehicle is coated
with a special compound to protect it
from chemical and mechanical influen-
However, as this protective layer gets
damaged when the vehicle is in use, the
coating under the body and on the runn-
ing gear should be examined at certain
intervals - preferably before and after
the winter season - and any damage
Every V.A.G workshop has stocks of the
correct compound, has the necessary
equipment and is familiar with the appli-
cation procedure. We advice you there-
fore to have the patching up or additional
coating done by a V.A.G workshop.
Note for vehicles with a catalyst
Due to the high temperatures which
occor in the afterburning process, ad-
ditional heat shields are fitted over the
catalyst. Underbody sealant must not
be applied to these shields, the catalyst
or the exhaust pipes.
Various cavities in the body are also pro-
tected against corrosion and this protec-
tion can be intensified by repetition of
The best results are obtained when the
first subsequent treatment is done about
one year after the vehicle is put on the
All V.A.G workshops know how and
where this treatment has to be carried
out and have the factory approved com-
pound and the equipment required.
Only the correct cleaning solutions may be
used - on no account petrol or Diesel.
