2007 SUZUKI FORENZA radiator cap

5-13 SERVICE AND APPEARANCE CARE

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.

If the warning continues and you have not
stopped, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle
the engine for three minutes while you’re
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 SystemThe engine coolant surge tank is located in
the rear of the engine compartment on the
driver’s side.If the coolant inside the coolant surge tank
is boiling, don’t do anything else until it
cools down. The vehicle should be parked
on a level surface. Make sure that the air
conditioning is turned off.
The coolant level should be between the
MIN and MAX marks on the coolant surge
tank when the engine is cool. If it isn’t, you
may have a leak at the pressure cap or in
the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cool-
ing system.If there seems to be no leak, with the
engine on, check to see if the electric
engine cooling fan is running. If the engine
is overheating, the fan should be running.
If it isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, check
to see if coolant is visible in the surge tank.
If coolant is visible but the coolant level
isn’t between the MIN and MAX marks,
add a 60/40 mixture of clean, drinkable
water and proper coolant at the coolant
surge tank, but be sure the cooling system,
including the coolant surge tank pressure
cap, is cool before you do it. See “Engine
Coolant” in this section for more informa-
tion.
If no coolant is visible in the surge tank,
add coolant as follows:
WARNING
An electric engine cooling fan under
the hood can start up even when the
engine is not running and can injure
you. Keep hands, clothing and tools
away from any underhood electric
fan.
WARNING
Heater and radiator hoses, and other
engine parts, can be very hot. Don’t
touch them. If you do, you can be
burned.
Don’t run the engine if there is a leak.
If you run the engine, it could lose all
of the coolant. That could cause an
engine fire, and you could be burned.
Get any leak fixed before you drive
the vehicle.
CAUTION
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
CAUTION
This vehicle has a specific coolant fill
procedure. Failure to follow this pro-
cedure could cause your engine to
overheat and be severely damaged.

1) Park the vehicle on a level surface. You
can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pres-
sure cap and upper radiator hose, is no
longer hot. Turn the pressure cap
slowly counterclockwise (left) about two
or two and one-half turns. If you hear a
hiss, wait for that to stop. This will allow
any pressure still left to be vented out
the discharge hose.
WARNING
Never turn the cap when the cooling
system, including the coolant surge
tank pressure cap, is hot.
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They are under pres-
sure, and if you loosen the coolant
surge tank pressure cap – even a lit-
tle – they can come out at high
speed. Wait for the cooling system
and coolant surge tank pressure cap
to cool if you ever have to loosen the
pressure cap.
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 a proper coolant.

CAUTION
In cold weather, water can freeze and
crack the engine, radiator, heater
core and other parts. Use the recom-
mended coolant and the proper cool-
ant mixture.
WARNING
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.
Don’t spill coolant on a hot engine.

2) Then keep turning the pressure cap
slowly, and remove it.
3) Fill the coolant surge tank with the
proper mixture to the MAX mark on the
coolant surge tank. Wait about five min-
utes, then check to see if the level is
below the MAX mark. If the level is
below the MAX mark, add additional
coolant to bring the level up to the MAX
mark. Repeat this procedure until the
level remains constant at the MAX mark
for at least five minutes.
4) With the coolant surge tank pressure
cap off, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If thelevel is lower than the MAX mark, add
more of the proper mixture to the cool-
ant surge tank until the level reaches
the MAX mark.
5) Then replace the pressure cap. Be sure
the pressure cap is hand-tight and fully
seated. See your SUZUKI dealer, if
necessary.
Power Steering FluidThe power steering fluid reservoir is
located toward the front of the engine com-
partment on the driver’s side of the vehicle.
See “Engine Compartment Overview” in
this section for more information on loca-
tion.
When to Check Power Steering Fluid
It is not necessary to regularly check
power steering fluid unless you suspect
there is a leak in the system or you hear an
unusual noise. A fluid loss in this system
could indicate a problem. Have the system
inspected and repaired.How to Check Power Steering Fluid
Turn the key off and then check the fluid
level. The level should be between the MIN
and MAX marks on the reservoir. If the
level is below the MIN mark, add power
steering fluid.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in
section 6. Always use the proper fluid. Fail-
ure to use the proper fluid can cause leaks
and can damage hoses and seals.
