1. INSPECT ENGINE COOLANT (See page 16-1)
2. INSPECT ENGINE OIL
3. INSPECT BATTERY
Standard specific gravity: 1.25 to 1.29 at 20C (68F)
4. INSPECT AIR CLEANER FILTER ELEMENT SUB-ASSY
5. INSPECT SPARK PLUG (See page 18-3)
6. INSPECT V-RIBBED BELT

(For vane pump)588 to 686
(60 to 70 , 132 to 154)245 to 392
(25 to 40 , 55 to 88)
NOTICE:
Check the drive belt deflection at the specified point.
When installing a new belt, set its tension value as
specified.
When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.
When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.
The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.
When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool
to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or
OBD II scan tool.
Ignition timing: 8 to 12 BTDC
HINT:
Refer to the hand-held tester or OBD II scan tool operator's
manual if you need help to select DATA LIST.

2005 LEXUS ES330 REPAIR MANUAL (RM1124U)
9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Remove the intake air surge tank (see page 11-13).
(c) Disconnect the injector connectors.
(d) Remove the ignition coils.
(e) Remove the spark plugs.
(f) Inspect the cylinder compression pressure.
(1) Insert a compression gauge into the spark plug
hole.
SST 09992-00500
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1.5 MPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure:
1.0 MPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi)
NOTICE:
Always use a fully-charged battery to obtain engine
speed of 250 rpm or more.
Check the other cylinder's compression pressure in
the same way.
This measurement must be done as quickly as pos-
sible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole, then inspect again.
HINT:
If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.
If pressure stays low, the valve may be sticking or seated
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
HINT:
The ECM properly controls the CO/HC concentration in the emission gas.
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check the CO/HC concentration at idle and/or at 2,500 rpm.
HINT:
When doing the 2 mode (with the engine is at idle and at 2,500 rpm) tests, these measuring order are pre-
scribed by the applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the heated oxygen sensor operation (see page 05-126).
