Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the FULL and LOW
lines on the reservoir when the engine is cold.
Reservoir cap
FULL
LOW
If the level is on or below the
LOW line, add coolant up to the
FULL line.
nIf the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
n Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
Except Canada:“Toyota Super Long Life Coolant” is a mixture of 50% cool- ant and 50% deionized water. (Enabled: -31 °F [-35 °C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 °F [-42 °C])
For more details about engine coolant, contact your Toyota dealer.
CAUTION
n When the engine is hot
