2004 Lexus ES330 check engine

ENGINE
377 Lexus recommends Toyota Super Long Life Coolantº which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper
usage. Toyota Super Long Life Coolantº is formulated with
long- life hybrid organic acid technology and has been
specifically designed to avoid engine cooling system
malfunction on Lexus vehicles.
Toyota Super Long Life Coolantº is pre- mixed with 50%
coolant and 50% distilled water. This coolant provides
protection down to about -35C (-31F).
Please contact your Lexus dealer for further details.
CHECKING THE RADIATOR AND
CONDENSER
If either of the above parts are extremely dirty or you are not
sure of their condition, take your vehicle to a Lexus dealer.
CAUTION
To prevent burning yourself, be careful not to touch the
radiator, condenser or intercooler when the engine is
hot.
NOTICE
To prevent damage to the radiator and condenser, do
not perform the work by yourself.

CHECKING POWER STEERING
FLUID
Check the fluid level through the reservoir. If necessary,
add automatic transmission fluid DEXRONII or III.
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60C Ð 80C or 140F Ð 175F). You may also check the
level when the fluid is cold (about room temperature, 10C Ð
30C or 50F Ð 85F) if the engine has not been run for about
five hours.

4If hot add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the COLDº range. Similarly,
if it is hot, the fluid level should be in the HOTº range. If the
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.
CAUTION
The reservoir may be hot so be careful not to burn
yourself.

box.
Determine which fuse may be causing the problem. The
auxiliary box shows the name of the circuit for each fuse.

ELECTRICAL COMPONENTS
429 It is a good idea to purchase a set of spare fuses and keep them
in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with
the electrical system. Have your Lexus dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher amperage rating, or any
other object, in place of a fuse. This may cause
extensive damage and possibly a fire.
