Corrosion protection
The engine compartment, as well as all engine,
transmission, front and rear axle assembly
surfaces have been treated with wax based
coating at the factory for protection against
corrosion.
When washing the engine compartment,
only use commercially available grease
cutting solvents made especially for this
purpose. Carefully follow directions print-
ed on the container by the manufacturer.
WARNING
Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
fold, exhaust pipes, catalytic converter or
heat shields. D u r i n g driving, the substance
used for undercoating could overheat and
cause a fire.
Engine Compartment
If it becomes necessary to steam clean or
otherwise wash the engine compartment, the
wax based protective coating is usually lost.
It is, therefore, important to reapply this pro-
tective coating to all engine compartment pa-
nels, flanges, cavities, s e a m s a n d e n g i n e as-
sembly surfaces.
Chassis
The lower body shell of your Porsche is thor-
oughly protected against corrosion. However,
it is recommended to have the underbody in-
spected twice a y e a r . A n y detected d a m a g e to
the undercoating, due to road hazards, should
be repaired promptly. Oil based protective
sprays must not be applied. Only tar or wax
based anti-corrosion protectors are compatible
with the factory applied undercoating. Before
application, road dirt and oily substances must
be removed.
Whenever the lower body shell, axle, trans-
mission or engine assemblies are repaired,
the lost anti-corrosion coating of the af-
fected surface should be renewed.
L e t your Porsche dealer advise and assist you.
