1999 LEXUS SC300 power steering fluid

MAINTENANCE
314
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page 396
for additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower
lines on the see±through reservoir when the engine is cold.
See page 347 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 380 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 359 for
additional information.
Engine oil level
Check the level on the dipstick with the engine turned off and
the vehicle parked on a level spot. See page 342 for additional
information.Power steering fluid level
Check the level on the dipstick. The level should be in the
ºHOTº or ºCOLDº range depending on the fluid
temperature. See page 361 for additional information.
Engine fan fluid level
Check the level through the reservoir. The level should be in
ºHOTº or ºCOLDº range depending on the fluid
temperature. See page 349 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or smell
exhaust fumes, have the cause located and corrected
immediately. (See engine exhaust cautions in Section 3±1.)

INTRODUCTION
325

Right after driving, the engine compartment ± the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. ± will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.

Do not smoke, cause sparks or allow open flames
near fuel or the battery. Their fumes are fl ammable.

Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Al ways use automotive jack stands or
other solid supports.

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
NOTICE

Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.

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.

Do not overfill automatic transmission fluid, or the
transmission could be damaged.

Be careful not to scratch the glass surface with the
wiper frame.
PARTS AND TOOLS
Here is a list of parts and tools you will need to perform
do±it±yourself maintenance. Remember all Lexus parts are
designed in metric sizes, so your tools must be metric.
Checking the engine oil level
Parts (if level is low):

Use API grade SJ, ºEnergy±Conservingº multigrade
engine oil or ILSAC multigrade engine oil. For
recommended oil viscosity, see page 346.
