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% deion-
ized water. (Minimum temperature: -35°C [-31°F])

If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump. If you cannot find a leak, have any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional test the cap
and check for leaks in the cooling system.
