CHECKING THE ENGINE COOLANT
LEVEL

1Reservoir cap2Fº (upper) line
3Lº (lower) line
Look at the see-through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the Fº and Lº lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see Coolant
type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the Lº line,
add coolant. Bring the level up to the Fº line.

ENGINE
546If the coolant level drops within a short time after replenishing,
there may be a leak in the system. Visually 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.
Coolant type selection
Use of improper coolants may damage your engine cooling
system.
Only use Toyota Super Long Life Coolantº or similar high
quality ethylene glycol based non- silicate, non- amine,
non- nitrite, and non- borate coolant with long- life hybrid
organic acid technology. (Coolant with long-life hybrid organic
acid technology consists of the combination of low phosphates
and organic acids.)
Toyota Super Long Life Coolantº is a mixture of 50% coolant
and 50% deionized water. This coolant provides protection
down to about -35C (-31F).
NOTICE
Do not use plain water alone.

ENGINE
547 Lexus recommends Toyota Super Long Life Coolantº which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper
usage. Toyota Super Long Life Coolantº is formulated with
long- life hybrid organic acid technology and has been
specifically designed to avoid engine cooling system
malfunction on Lexus vehicles.
Please contact your Lexus dealer for further details.

sure of their condition, take your vehicle to a Lexus dealer.
CAUTION
To prevent burning yourself, be careful not to touch the
radiator or condenser when the engine is hot.
NOTICE
To prevent damage to the radiator and condenser, do
not perform the work by yourself.
