350
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in
the acceptable range, turn off the engine and call your
Lexus dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or
your vehicle overheats again, have it checked as soon
as possible by your Lexus dealer.IF YOU HAVE A FLAT TIRE

Look at the see±through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it
is between the ªFULLº and ªLOWº 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
ªLOWº line, add coolant. Bring the level up to the ªFULLº
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.
