Add only “T oyota 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 to fill the
radiator. “Toyota Super Long Life Coolant” is a

If you spill some of the coolant, be sure to wash it off
with water to prevent it from damaging the parts or
paint.
Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.
Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.
