2007 SUZUKI FORENZA oil temperature

5-9 SERVICE AND APPEARANCE CARE
85Z03-03E
If you are in an area of extreme cold,
where the temperature falls below –22°F
(–30°C), it is recommended that you use
either an SAE 5W-30 synthetic oil or an
SAE 0W-30 oil. Both will provide easier
cold starting and better protection for your
engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. The recom-
mended oils with the starburst symbol are
all you will need for good performance and
engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
 Most trips are less than 5 miles (8 km).
This is particularly important when out-
side temperatures are below freezing.
 Most trips include extensive idling (such
as frequent driving in stop-and-go traf-
fic).
 The vehicle is used for delivery service,
police, taxi or other commercial applica-
tion.Driving under these conditions causes
engine oil to break down sooner. If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,750 miles (6,000 km) or 3 months –
whichever occurs first.
If none of them is true, use the long trip/
highway maintenance schedule. Change
the oil and filter every 7,500 miles (12,000
km) or 6 months – whichever occurs first.
Driving a vehicle with a fully warmed
engine under highway conditions will
cause engine oil to break down slower.
What to Do with Used Oil
Used engine oil contains certain elements
that may be unhealthy for your skin and
could even cause cancer. Don’t let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly dis-
pose of clothing or rags containing used
engine oil. See the manufacturer’s warn-
ings about the use and disposal of oil prod-
ucts.
Used oil can be a threat to the environ-
ment. If you change your own oil, be sure
to drain all the oil from the filter before dis-
posal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into
sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of your used oil, askyour SUZUKI dealer, a service station or a
local recycling center for help.
Engine Air Cleaner/FilterThe engine air cleaner/filter is located on
the passenger’s side of the engine com-
partment. See “Engine Compartment
Overview” in this section for more informa-
tion on location.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter every 7,500
miles (12,000 km) or 6 months – whichever
occurs first.
Replace every 30,000 miles (48,000 km)
or 24 months – whichever comes first.
If you are driving in dusty/dirty conditions,
inspect the filter every 3,750 miles (6,000
CAUTION
Use only engine oil with the Ameri-
can Petroleum Institute Certified For
Gasoline Engines starburst symbol.
Failure to use the recommended oil
can result in engine damage not cov-
ered by your warranty.

5-13 SERVICE AND APPEARANCE CARE
85Z03-03E
If you have to add coolant more than four
times a year, have your SUZUKI dealer
check your cooling system.Checking Coolant
The engine coolant surge tank is located
on the driver’s side of the engine compart-
ment. See “Engine Compartment Over-
view” in this section for more information
on location.The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be between MAX and MIN mark on
the coolant surge tank. The level rises at
engine operation temperature and drops
again when the engine cools down.
Adding Coolant
If the level falls below the MIN mark, add
the proper coolant mixture at the surge
tank, but only when the engine is cool. If
the surge tank is empty, a special fill proce-
dure is necessary. See “Cooling System”
in this section for instructions on “How to
Add Coolant to the Coolant Surge Tank”.
WARNING
Adding only plain water to your cool-
ing system can be dangerous. Plain
water, or some other liquid such as
alcohol, can boil before the proper
coolant mixture will. Your vehicle’s
coolant warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, your
engine could get too hot but you
wouldn’t get the overheat warning.
Your engine could catch fire and you
or others could be burned. Use a 60/
40 mixture of clean, drinkable water
and the proper coolant.
CAUTION
If you use an improper coolant mix-
ture, your engine could overheat and
be badly damaged. The repair cost
wouldn’t be covered by your war-
ranty. Too much water in the mixture
can freeze and crack the engine, radi-
ator, heater core and other parts.
CAUTION
If you use the proper coolant, you
don’t have to add extra inhibitors or
additives which claim to improve the
system. These can be harmful.
WARNING
Never turn the surge tank pressure
cap – even a little – when the engine
and radiator are hot.
Loosening the surge tank pressure
cap when the engine and radiator are
hot can allow steam and scalding liq-
uids to blow out and burn you badly.
WARNING
Don’t spill coolant on a hot engine.
You can be burned if you spill coolant
on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough.
