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 an authorised Volvo workshop for
assistance.
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:
• Thin (colourless), for visible areas.
• 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, col-
ourless rustproofing. This withstands normal
detergents without dissolving and losing its
rustproofing ability.
If you wash the engine using aromatic sol-
vents, such as turpentine or white spirit
(especially those that do not contain emulsifi-
ers), the protective wax should be renewed
after washing. Your Volvo dealer handles
such waxes.
