Maintenance
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the vis-
ible surfaces but particularly to the
underside of the vehicle.
To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-

Keep your vehicle clean
The best way to prevent corrosion is
to keep your vehicle clean and free
of corrosive materials. Attention to
the underside of the vehicle is partic-
ularly important.
• If you live in a high-corrosion area
— where road salts are used, near
the ocean, areas with industrial pol-
lution, acid rain, etc.—, you should
take extra care to prevent corrosion.
In winter, hose off the underside of
your vehicle at least once a month
and be sure to clean the underside
thoroughly when winter is over.
• When cleaning underneath the
vehicle, give particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will
accelerate corrosion rather than
prevent it. Water under high pres-
sure and steam are particularly
effective in removing accumulated
mud and corrosive materials.
• When cleaning lower door panels,
rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.
