179 If 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.
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 171. We recommend 50% solution be used for
your Lexus, or a sufficient quantity to provide protection to
about −35
C (−31
F).
NOTICE:
Do not use alcohol type antifreeze or plain water alone.
CHECKING AND REPLACING THE
AIR CLEANER FILTER
To inspect the filter, follow the procedure below.
1. Release 4 clips.

ENGINE
1802. Raise the cover and take out the filter.
Inspect the lower surface of the filter. If it is dirty, it should be
replaced. If it is just moderately dusty, it may be cleaned by
blowing compressed air from the direction of the upper
surface. Do not wash or oil the filter.
When installing a filter, be sure to remove any dust from where
the filter sits and put the filter properly in place.
NOTICE:
Do not drive with the air cleaner removed, or excessive
engine wear could result. Also backfiring could cause a
fire in the engine compartment.
