ENGINE
We recommend to use 50% solution for your Lexus, to provide
protection down to about –35_C (–31_F). When it is extremely
cold, to provide protection down to about –50_C (–58_F), 60%
solution is recommended. Do not use more than 70% solution
for better coolant performance.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
The engine cooling system is integral to maximizing
performance of your Lexus vehicle. In line with this, it is
strongly recommended that you use "Toyota Genuine Long
Life Coolant" for protecting the system, as it is an
ethylene–glycol based premium antifreeze coolant with
excellent corrosion protection properties that has been
specifically formulated for use in Lexus vehicles.
Please contact your Lexus dealer for further details of the
"Toyota Genuine Long Life Coolant" range.

To prevent yourself from burning, be careful not to
touch the radiator or condenser when the engine is hot.

To prevent damage to the radiator and condenser, do
not perform the work by yourself.
