Rustproofing - Volvo V70 Owner's Manual

Rustproofing

Rustproofing - check and repair
Your Volvo received a very thorough and complete rustproofing at the
factory. The body consists of galvanized sheet steel. The underbody is
protected by a wear-resistant anti-corrosion compound. Members, cavities
and enclosed sections are sprayed internally with a thin, penetrating rust
inhibitor.
The car's rustproofing is maintained by doing the following:
· Keep the car clean! Wash the underbody with a high-pressure
hose.When high pressure washing - hold the spray nozzle at least
30 cm away from painted surfaces!
· Check and repair eventual rustproofing regularly.
The car's rustproofing does not normally require treatment for approxima-
tely 8 years. After that time, it should be treated at three year intervals. If
your car requires treatment, consult your Volvo workshop.

Improvement
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.
Two types of rustproofing agent are available:
a) thin (colourless), for visible places
b) thick, for wear areas 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
When you have finished applying the rustproofing agent, wipe off any
surplus fluid using a cloth moistened with a recommended detergent.
Parts of the engine and suspension strut mountings in the engine compart-
ment are treated at the works with a wax-based colourless rustproofing
agent. This withstands normal detergents without dissolving and losing its
rustproofing ability. On the other hand, if you wash the engine using
aromatic solvents such as turpentine or white spirit (especially those
which do not contain emulsifiers), the protective wax should be renewed
after washing. Your Volvo dealer has such waxes in stock.
