ENGINE
198If the coolant level drops within a short time after
replenishing, there may be a leak in the system. Visually
check the radiator, hoses, reservoir cap, drain cock and
water pump.
If you can find no leak, have your Lexus dealer test the cap
pressure and check for leaks in the cooling system.
CAUTION!
To prevent burning yourself, do not remove the
reservoir cap when the engine is hot.
Engine coolant 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 191. 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.
