If the cooling system frequently requires
coolant, have it checked by an INFINITI
dealer.
CHANGING ENGINE COOLANT O Major cooling system repairs should be
performed by an INFINITI dealer. The
service procedures can be found in the
appropriate INFINITI Service Manual. O Improper servicing can result in re-
duced heater performance and engine
overheating.
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 cool-
ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as
soon as possible.
O Keep coolant out of reach of children and
pets.
1. Open radiator drain plug
q A
at the
bottom of radiator, and remove ra-
diator filler cap
q B
.
O Be careful not to allow coolant to con-
tact drive belts.
O Waste coolant must be disposed of
properly. Check your local regulations. SDI0114B

2. Close the radiator drain plug securely
after the coolant is drained.
3. Fill the radiator slowly with the proper
mixture of antifreeze solution and
demineralized 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 tempera-
ture. Then race the engine 2 or 3 times
under no load. Watch the engine cool-
ant temperature 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. Check the coolant level again after
driving the vehicle.
CHECKING ENGINE OIL LEVEL 1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operat-
ing temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick
q A
and wipe it
clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the
H and L marks
q B
. If the oil level is
below the L mark
q A
, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
q C
.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
maintenance intervals or during the break-
in period, depending on the severity of op-
erating conditions. SDI1386D SDI1781
