PRECAUTION
1. HANDLING PRECAUTIONS ON STEERING SYSTEM
(a) Care must be taken to when replacing parts. Incorrect re-
placement could affect the performance of the steering
system and result in a driving hazard.
(b) 1MZ-FE engine has 2 types of vane pump assy.
HINT:
TYPE A VANE PUMP
Vane pump pulley can be removed from the vane pump shaft
(See page 51-7).
TYPE B VANE PUMP
Vane pump pulley cannot be removed from the vane pump
shaft (See page 51-7).
2. HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM
(a) The LEXUS ES330 is equipped with SRS (Supplemental Restraint System) such as the driver airbag
and front passenger airbag. Failure to carry out service operation in correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing
(including removal or installation of parts, inspection or replacement), be sure to read the precaution-
ary notice for the supplemental restraint system (See page 60-1).

ON-VEHICLE INSPECTION
1. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords,
etc.
If any defect is found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
missing chunks from the ribs are found on the belt, it should be
replaced.
2. BLEED POWER STEERING SYSTEM
(a) Check the fluid level.
(b) Jack up the front of the vehicle and support it with the
stands.
(c) Turn the steering wheel.
(1) With the engine stopped, turn the wheel slowly from
lock to lock several times.
(d) Lower the vehicle.
(e) Start the engine.
(1) Run the engine at idle for a few minutes.
(f) Turn the steering wheel.
(1) With the engine idling, turn the wheel to left or right
full lock position and keep it there for 2 - 3 seconds,
then turn the wheel to the opposite full lock position
and keep it there for 2 - 3 seconds.
(2) Repeat (1) several times.
(g) Stop the engine.
(h) Check for forming or emulsification.
Especially, if the system has to be bled twice because of foam-
ing or emulsification, check for fluid leaks in the system.
(i) Check the fluid level.
3. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir cap. If the fluid is cold, check that it is within the COLD
LEVEL range.

(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
raise fluid temperature.
Fluid temperature: 75 - 80°C (167 - 176°F)
(e) Check for foaming or emulsification.
If foaming or emulsification is identified, bleed the power steer-
ing system.
(f) With the engine idling, measure the fluid level in the oil
reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed the power steering system.
(i) Check the fluid level.
4. CHECK STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube assy from the rack &
pinion power steering gear assy (See page 51-21).
(b) Connect SST, as shown in the illustration.
SST 09640-10010 (09641-01010, 09641-01020,
09641-01030)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system.
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
raise fluid temperature.
Fluid temperature: 75 - 80 °C (167 - 176 °F)
