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.
U.S.A.:

“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water.

(Minimum temperature: -31

F [-35C])

Canada:

“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water.

(Minimum temperature: -44

F [-42C])

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 reservoir 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.

WARNING

■

When the engine is hot
Do not remove the engine coolant reservoir cap, the intercooler coolant reservoir cap

or the coolant inlet cap. (

P. 516)

The cooling system may be under pressure and may spray hot coolant if the cap is

removed, causing serious injuries, such as burns.

NOTICE

■

When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water and

antifreeze must be used to provide proper lubrication, corrosion protection and cool-

ing. Be sure to read the antifreeze or coolant label.

■

If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
