CHANGING ENGINE COOLANTIMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.IImproper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
ITo avoid being scalded, never change
the coolant when the engine is hot.
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
IAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
IKeep coolant out of reach of children
and pets.
1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from OFF to ON.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to

IBe careful not to allow coolant to con-
tact drive belts.
IWaste coolant must be disposed of
properly. Check your local regulations.
3. Close the radiator drain valve securely after
the coolant is drained.
4. 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.
5. 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 temperature
gauge for signs of overheating.

TEMPERATURE CONDITIONS
FOR CHECKINGIThe fluid level should be checked using the
HOT range on the dipstick after the follow-
ing conditions have been met:
a) the engine should be warmed up to
operating temperature.
b) the vehicle should be driven at least 5
minutes.
c) the automatic transmission fluid should
be warmed to between 122 and 176ÉF
(50 and 80ÉC).
IThe fluid can be checked at fluid tempera-
tures of 86 to 122ÉF (30 to 50ÉC) using the
COLD range on the dipstick after the en-
gine is warmed up and before driving. How-
ever, the fluid should be re-checked using
the HOT range.
1. Park the vehicle on a level surface and set
the parking brake.
2. Start the engine and then move the selector
lever through each gear range. Move the
selector lever to P (Park) position after you
have moved it through all ranges.3. Check the fluid level with the engine idling.
4. Remove the dipstick and wipe it clean with
lint-free paper.
5. Reinsert the dipstick into the charging pipe
as far as it will go.
6. Remove the dipstick and note the reading.
If the level is at the low side of either range,
add fluid to the charging pipe.

REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See the separate Service and
Maintenance Guide. When replacing the filter,
wipe the inside of the air cleaner housing and
the cover with a damp cloth.
WARNING
IOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleanernot only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
