1999 Lexus ES300 coolant reservoir

MAINTENANCE
355
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
432 for additional information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and
ºLOWº lines on the see±through reservoir when the
engine is cold. See page 383 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 415 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 391
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 378 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ºHOTº or ºCOLDº range depending on the fluid temperature. See page 393 for additional information.
Exhaust system
Look
for cracks, holes and loose supports. 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.)

Look at the see±through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it
is between theºFULLº and ºLOWº lines on the
reservoir. If the level is low, add ethylene±glycol
type coolant for a proper corrosion protection of
aluminum components.
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the
ºLOWº line, add coolant. Bring the level up to the ºFULLº
line.
Always use ethylene±glycol type coolant for a proper
corrosion protection of aluminum components. See
information in the next column. If the coolant level drops within a short time after
replenishing,
there may be a leak in the system. V isually
check the radiator, hoses, engine coolant filler cap,
radiator cap and 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.
