1995 Oldsmobile Cutlass Supreme engine

Underbody Maintenance
Chemicals used for ice and snow.removal and dust
control can collect on the underbody.
If these .are not
removed, accelerated coirosion (rust) can occur on the
underbody
parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your retailer
or an underbody vehicle -washing system
can do this for you.
Fiberglass Springs
I
NOTICE: 1
Don’t use corrosive or acidic cleaning agents,
engine degreasers, aluminum cleaning agents or
other harsh solvents to clean fiberglass springs;
they’ll damage the springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on,your vehicle. This
damage can take two
forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched
into the paint surface.
Although
no defect in the paint job causes this,
Oldsmobile will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition within
12 months or 12,000 miles (20 000 h)
of purchase, whichever comes first.
