2008 CHEVROLET EXPRESS PASSANGER low oil pressure

If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues, and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, push down the
accelerator until the engine speed is about twice as fast
as normal idle speed for at least three minutes while
you are parked. If you still have the warning, turn off the
engine and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right away.
Cooling System
If your vehicle has a diesel engine, see “Van Models”
under “Cooling System” in the DURAMAX®Diesel
Supplement.When you decide it is safe to lift the hood, here is what
you will see:
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Cooling Fan(s)
If the coolant inside the coolant recovery tank is boiling,
do not do anything else until it cools down.

When cleaning your vehicle’s interior, only use cleaners
specifically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger. When cleaning the glass on your
vehicle, use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space. Before
using cleaners, read and adhere to all safety
instructions on the label. While cleaning your vehicle’s
interior, maintain adequate ventilation by opening
your vehicle’s doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your dealer/retailer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your dealer/retailer to remove
odors from your vehicle’s upholstery.Do not clean your vehicle using the following cleaners
or techniques:
•Never use a knife or any other sharp object to
remove a soil from any interior surface.
•Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
•Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure
can damage your interior and does not improve the
effectiveness of soil removal.
•Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers.
Using too much soap will leave a residue that
leaves streaks and attracts dirt. For liquid cleaners,
about 20 drops per gallon (3.78 L) of water is a
good guide.
•Do not heavily saturate your upholstery while
cleaning.
•Damage to your vehicle’s interior may result from
the use of many organic solvents such as naptha,
alcohol, etc.

Follow all manufacturers’ directions regarding correct
product usage, necessary safety precautions and
appropriate disposal of any vehicle care product.
Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting
High pressure car washes may cause water to enter the
vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
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 underWashing Your Vehicle on
page 5-102.
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint finish. You can get approved cleaning products
from your dealer/retailer. SeeVehicle Care/Appearance
Materials on page 5-107.
If your vehicle has a basecoat/clearcoat paint finish, 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 finish.
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 finish 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.
