CHECKING THE ENGINE
COOLANT LEVEL

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.
