Rustproofing - Volvo 2005 S80 Owner's Manual

Rustproofing

Rustproofing - check and repair
Your Volvo received a very thorough and complete rustproofing at the
factory. Areas that are extremely vulnerable, such as the underbody,
have been sprayed with a thick, wear-resistant anti-corrosion compound
on the outside. 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 chassis components*, the underbody,
and the inside and edges of wheel arches with a pressure washer.
When high pressure washing - hold the spray nozzle at least 30 cm
away from painted surfaces!
· Check and repair the rustproofing regularly.
* Trailing arms, link arms, spring mountings and spring strut seats.
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.

Improving
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 areas prone to wear on the underbody and in the wheel
arches
Possible repair areas with these agents:
·
Visible welds and sheet metal joints - thin fluid
·
Underbody and wheel arches - thick fluid
·
Door hinges - thin fluid
·
Bonnet hinges and catch - thin fluid
When you have finished treatment, excess rustproofer can be wiped off
using a rag dampened with white spirit.
Parts of the engine and suspension strut mountings in the engine bay
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.
