CHECKING THE ENGINE COOLANTLEVEL
62X003d
 1Radiator cap 2“FULL” line 3“LOW” line
Look at the seethrough coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the“FULL” and “LOW” lines on the reservoir. If
the level is low, add the coolant. (For the coolant type, see
“Coolant type selection” described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the “LOW”
line, add coolant. Bring the level up to the “FULL” line. If the coolant level drops within a short time after replenishing,
there
may be a leak in the system. V isually check the radiator,
hoses, engine coolant filler cap, radiator cap and drain cock
and water pump.
If you can find no leak, have your Lexus dealer test the radiator
cap pressure and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.
