changing coolant INFINITI G35 2003 Owners Manual

FREEING A FROZEN DOOR LOCK To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.
ANTI-FREEZE In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cool-
ing Systemº in the ª8. Do-it-yourselfº section.
BATTERY If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see ªBatteryº in the ª8. Do-it-
yourselfº section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain plug located under the radiator.
Refill before operating the vehicle. See ªEn-
gine cooling systemº in the ª8. Do-it-yourselfº
section for changing engine coolant. TIRE EQUIPMENT 1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Please consult your INFINITI retailer for the
tire type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded
tires may be used. However, some prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-
stalling studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
3. Tire chains may be used if desired. Make
sure they are of proper size for the tires on
your vehicle and are installed according to
the chain manufacturer's suggestions. Use
of tire chains may be prohibited according
to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are in- stalled according to the chain manufactur-
er's suggestions. Use only SAE Class S
chains. Class ªSº chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class ªSº
chains are designed to meet the SAE stan-
dard minimum clearances between the tire
and the closest vehicle suspension or body
component required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped tire
size. Other types may damage your ve-
hicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to pre-
vent the possibility of whipping action dam-
age to the fenders or underbody. If pos-
sible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.

CHANGING ENGINE COOLANT O Major cooling system repairs should be
performed by your INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual. O Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING O To avoid being scalded, never change
the coolant when the engine is hot.
O Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
O Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
O Keep coolant out of reach of children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.
O Be careful not to allow coolant to con-
tact drive belts.
O Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained. 3. Fill the radiator slowly with the proper mix-
ture of anti-freeze solution and demineral-
ized water/distilled water. Fill the reservoir
tank up to the MAX level. Then install the
radiator filler cap.
4. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under no
load. Watch the engine coolant tempera-
ture gauge for signs of overheating.
5. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level. Check the drain plug for any
sign of leakage.
6. Recheck the coolant level after the vehicle
has been driven for a day.SDI0114
