ENGINE
170If no leak can be found, have the cap pressure tested at your
Lexus dealer.
CAUTION:
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.
Coolant type selection
Your coolant must contain ethylene-glycol antifreeze. In
addition to preventing freezing and subsequent damage to the
engine, this will also prevent corrosion. Further supplemental
inhibitors or additives are neither needed nor recommended.
Read the antifreeze container for information on freeze
protection. Follow the manufacturer’s directions for how much
to mix with water. The total capacity of the cooling system is
given on page 163. We recommend 50% solution be used for
your Lexus, or a sufficient quantity to provide protection to
about − 35C (− 31F).
NOTICE:
Do not use alcohol type antifreeze or plain water alone.
