6-3. Do-it-yourself maintenance

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 mixture of 50% coolant and 50% deionized water.

(Enabled: -35C [-31F])

For more details about engine coolant, contact your Lexus dealer.

If the coolant level drops within a short time of replenishing

Visually check the radiator, hoses, engine coolant reservoir cap, radiator cap, 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.

When the engine is hot

Do not remove the radiator cap, or the coolant reservoir cap.

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

removed, causing serious injuries, such as burns.

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 damage to parts or paint.

Radiator, condenser and intercooler (if equipped)

Check the radiator, condenser and intercooler and clear any foreign objects.

If either of the above parts is extremely dirty or you are not sure of their condi-

tion, have your vehicle checked by your Lexus dealer.
