OIL FILTER SUB-ASSY (3MZ-FE)
REPLACEMENT
CAUTION:

Prolonged and repeated contact with engine oil will cause removal of natural oils from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially
harmful contaminants which may cause skin cancer.

Precautions should be taken when replacing engine oil to minimize the risk of your skin making
contact with used engine oil. Wear protective clothing and gloves. Wash your skin thoroughly
with soap and water, or use water-less hand cleaner to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

For environmental protection used oil and used oil filter must be disposed of at designated dis-
posal sites.
1. REMOVE ENGINE UNDER COVER NO.1
2. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, then drain the oil into a container.
(c) Clean and install the oil drain plug with a new gasket.
Torque: 45 NVm (459 kgfVcm,
33 ftVlbf)
3. REMOVE OIL FILTER SUB-ASSY
(a) Using SST, remove the oil filter.
SST 09228-07501
4. INSTALL OIL FILTER SUB-ASSY
(a) Check and clean the oil filter installation surface.
(b) Apply clean engine oil to the gasket of a new oil filter.
(c) Lightly screw the oil filter into place, then tighten it until the
gasket contacts the seat.
(d) Using SST, tighten it an additional 3/4 turn.

(14F) to 50C (122F) and ºHotº is from 50C (122F) to 100C (212F).
1. INSPECT IGNITION COIL AND SPARK TEST
(a) Check the DTCs.
NOTICE:
If a DTC is present, perform troubleshooting in accordance with a procedure for that DTC.
(b) Check that a spark occurs.
(1) Remove the 6 ignition coils (see page 18-7).
(2) Using a spark plug wrench 16 mm, remove the 6 spark plugs.
Torque: 25 NVm (250 kgfVcm, 18 ftVlbf)
(3) Install the spark plugs to each ignition coil, then connect the ignition coil connectors.
(4) Disconnect the 6 fuel injector connectors.
(5) Ground the spark plugs.
(6) Check that the spark plug occurs at each spark plug while the engine is being cranked.
NOTICE:

Be sure to ground the spark plugs when checking.

Replace the ignition coil if physical impact is felt.

Do not crank the engine for more than 2 seconds.
If a spark does not occur, perform the following test.
1 SPARK TEST

4 CHECK POWER SUPPLY TO IGNITION COIL
(a) Turn the ignition switch ON.
(b) Check that there is battery voltage at the ignition coil positive (+) terminal.

INSPECTION
1. INSPECT SPARK PLUG
NOTICE:

Do not use a wire brush to clean the spark plug.

Do not try to adjust the electrode gap of a used spark
plug.
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the insulation and body ground.
Resistance: 10 MW or more
If the resistance is not as specified, check the electrode gap.
(b) Alternative inspection method.
(1) Quickly accelerate the engine speed to 4,000 rpm
5 times.
(2) Remove the spark plug.
(3) Visually check the spark plug.
(4) If the electrode is dry...OK.
(5) If the electrode is wet...Proceed to step (c).
(6) Reinstall the spark plug.
(c) Check the appearance.
(1) Check the thread and insulator of the spark plug for
damage.
If damaged, replace the spark plug.
Recommended spark plug:
SupplierType
DENSOSK20R11
NGKIFR6A11
(d) Inspect the electrode gap.
(1) Using a spark plug gauge, measure the electrode
gap.
Maximum electrode gap of used spark plug:
1.3 mm (0.051 in.)
If the electrode gap is greater than maximum, replace the spark
plug.
Electrode gap of new spark plug:
1.0 to 1.1 mm (0.039 to 0.043 in.)

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).
