Coolant selection
Only use “Toyota Super Long Life Coolant”
or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C [-
31°F])
For more details about coolant, contact
your Lexus dealer.

If the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses, engine
coolant/power control unit coolant reser-
voir caps, drain cock and water pump.
If you cannot find a leak, have your Lexus
dealer, test the cap and check for leaks in
the cooling system.
