check engine NISSAN SENTRA 1998 B14 / 4.G User Guide

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
detect abnormal noise, etc., take the follow-
ing steps.
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
shift lever to N (Neutral) (manual trans-
mission) or the shift selector lever to P
(Park) (automatic transmission).
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air condi-
tioner temperature control to maximumhot and fan control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, the running
fan, belts, or fan motor. The fan motor
can start at any time when the coolant
temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at an authorized NISSAN
dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors;
therefore, additional engine cooling system
additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ratio
of 50% anti-freeze and 50% distilled
water. The use of other types of coolant
solutions may damage the engine cool-
ing system.

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Seriousburns could be caused by high pres-
sure fluid escaping from the radia-
tor.
cSee precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section of this manual.
c
The radiator is equipped with a pres-
sure cap. Use only a genuine NISSAN
cap when replacement is required.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by an authorized NISSAN
dealer. The service procedures can befound in an appropriate NISSAN Service
Manual.
cImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

9. 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.
10. Open and close the air release plug(s)
to release air. Then fill the radiator again
and install the radiator cap.
11. Check the drain plugs on the radiator
and the engine block for any sign of
leakage. Also check the air release plug
for any sign of leakage.CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.3. Turn off the engine.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick 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
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.

6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating with an insufficient amount
of oil can damage the engine, and such
damage is not covered by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature, and then turn it off.
3. Remove the oil filler cap.
4. Place a large drain pan under the drain
plug.
5. Remove the drain plug with a wrench and
completely drain the oil.If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing engine oil filter'' later in this section.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
Waste oil must be disposed of properly.
Check your local regulations.

6. Clean and reinstall the drain plug and
washer. Securely tighten the drain plug
with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N²m)
Do not overtighten.
7. Refill engine with recommended oil
through the oil filler opening then install
the oil filler cap securely.
See the ``Technical and consumer infor-
mation'' section for refill capacity.8. Start the engine. Check for leakage
around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
WARNING
cProlonged and repeated contact with
used engine oil may cause skin can-
cer.
cTry to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep used engine oil out of reach of
children.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil
filter.
4. Loosen the oil filter with an oil filter
wrench. Then remove the oil filter by
turning it by hand.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.

5. Wipe the engine oil filter mounting sur-
face with a clean rag.
Be sure to remove any old gasket mate-
rial remaining on the mounting surface of
the engine.
6. Coat the gasket on the new filter with
clean engine oil.
7. Screw on the oil filter until a slight resis-
tance is felt, then tighten an additional
2/3 turn.
8. Start the engine and check for leakage
around the oil filter. Correct as required.9. Turn the engine off and wait several
minutes. Check the oil level. Add engine
oil if necessary.WARNING
cWhen engine is running, keep
hands, jewelry and clothing away
from any moving parts such as cool-
ing fan and drive belts.
cAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
