1998 Lexus LS400 coolant capacity

GAUGES, METERS AND SERVICE REMINDER INDICATORS
34
FUEL GAUGE
13L0011
Low fuel level warning light
The gauge is displayed when the ignition switch is on and
indicates the approximate quantity of fuel remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ”E” or the low fuel level warning light
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank, the
fuel gauge needle may fluctuate or the low fuel level warning light
may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator lamp
comes on. Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as soon as
possible.
See the inner back cover for fuel capacity and recommended fuelselection.
ENGINE COOLANT
TEMPERATURE GAUGE
13L0022
Normal range
The gauge indicates the engine coolant temperature when the
ignition switch is on. The engine operating temperature will
vary with changes in weather and engine load.
If the needle points to the red zone or higher, stop your vehicle and
allow the engine to cool.
Your vehicle may overheat during severe operating conditions, such
as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high speed driving.

CHECKING THE ENGINE
COOLANT LEVEL
62L007-2
1
Reservoir cap 2
Upper line 3
Lower line
Park the vehicle at a level spot and look at the seethrough
coolant reservoir when the engine is cool. The coolant level is
satisfactory if it is between the upper and lower lines on the tank.
If the level is low, add ethyleneglycol type coolant.
The coolant level in the reservoir will vary with engine coolant
temperature. However, if the level is on or below the lower line, add
coolant to bring the level up to the upper line.
Use only ethyleneglycol type coolant. It will prevent freezing and
corrosion. Neither supplemental inhibitors nor additives are needed
nor recommended. (For information on ethyleneglycol coolant,
see also ”Engine coolant selection” described below.)If the coolant level drops within a short time after replenishing, there
may be a leak in the system. Visually check the radiator, hoses,
reservoir cap, drain cock and water pump.
If you can find no leak, have your Lexus dealer test the cap pressure
and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the reservoir cap
when the engine is hot.
Engine coolant selection
Your coolant must contain ethyleneglycol antifreeze. In addition
to preventing freezing and subsequent damage to the engine, this
will also prevent corrosion. Further supplemental inhibitors or
additives are neither needed nor recommended.
Read the antifreeze container for information on freeze protection.
Follow the manufacturer’s directions for how much to mix with
water. The total capacity of the cooling system is given on page 226.
We recommend 50% solution be used for your Lexus, or a sufficient
quantity to provide protection to about 35C (31F).
NOTICE
Do not use alcohol type antifreeze or plain water alone.

GAS STATION INFORMATION
Fuel selection:
Select premium unleaded gasoline with an Octane Rating of 91
