2003 CHEVROLET VENTURE oil pressure

Don't wash your vehicle in the direct rays of the sun.
Use a car washing soap. Don't use strong soaps
or chemical detergents. Be sure to rinse the vehicle
well, removing all soap residue completely. You can get
GM-approved cleaning products from your dealer.
See
Vehicle Care/Appearance Materials on page 5-94.
Don't use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be ¯ushed promptly and not allowed to dry on the
surface, or they could stain. Dry the ®nish with a soft,
clean chamois or an all-cotton towel to avoid surface
scratches and water spotting.
Before you enter an automatic car wash, if your vehicle
is equipped with the optional power sliding door, be
sure to have the switch for the power sliding door
override feature enabled. See
Power Sliding Door (PSD)
on page 2-17.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under ªWashing Your Vehicleº
previously.
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint ®nish. You can get GM-approved cleaning products
from your dealer. See
Vehicle Care/Appearance
Materials on page 5-94.
If your vehicle has a ªbasecoat/clearcoatº paint ®nish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint ®nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint ®nish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint ®nish on your vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc.,
can damage your vehicle's ®nish if they remain
on painted surfaces. Wash the vehicle as soon as
possible. If necessary, use non-abrasive cleaners that
are marked safe for painted surfaces to remove
foreign matter.

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace as needed. Clean the

To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.

Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
All-Wheel Drive Inspection
Inspect the transfer case (power transfer unit) and
carrier assembly-differential (rear drive module) every
12 months or at engine oil change intervals, check rear
differential and transfer case and add lubricant when
necessary. A ¯uid loss could indicate a problem; check
and have it repaired, if needed. Check vent hoses at
transfer case and differential for kinks and proper
installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
