Rustproofing
Rustproofing – check and repair
Your car received a thorough and complete
rustproofing at the factory. Parts of the body are
made of galvanised sheet metal. The underbody
is protected by a wear-resistant anti-corrosion
compound. Members, cavities and enclosed
sections are sprayed with a thin, penetrating rust
inhibitor.
The car's rustproofing is maintained by doing
the following:
• Keep the car clean! Hose down the
underbody.
During high pressure washing - hold the
nozzle at least 30 cm from painted surfaces!
• Check and repair the rustproofing regularly.
The car's rustproofing does not normally
require treatment for approximately 8 years.
After that time, it should be treated at three year
intervals. If your car requires treatment, consult
your Volvo workshop.
Repair
If you want to repair the rustproofing yourself,
make sure the area is clean and dry. Hose down,
wash and dry the car thoroughly. Use a
rustproofing agent in a spray can or one that is
intended for brush application.
There are two different types of rustproofing
agents:
a) thin (colourless), for visible areas
b) thick, for areas prone to wear on the
underbody
Possible repair areas with these agents:
• Visible welds and sheet metal joints - thin
fluid
• Underbody - thick fluid
• Door hinges - thin fluid
• Bonnet hinges and catch - thin fluid
Once you have finished treatment, excess
rustproofing can be wiped off with a rag dipped
in a recommended cleaning agent. Parts of the
engine and suspension strut mountings in the
engine compartment are treated at the factory
with a wax-based, colourless rustproofing. This
withstands normal detergents without
dissolving and losing its rustproofing ability.
If you wash the engine using aromatic solvents,
such as turpentine or white spirit (especially those
that do not contain emulsifiers), the protective
wax should be renewed after washing. Your
Volvo dealer handles such waxes.
