AIR CONDITIONING SYSTEM
PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN
YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin.
(a) Wash the area with lots of cool water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER AND NOT
TO APPLY PHYSICAL SHOCKS TO IT
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM
If there is not enough refrigerant in the refrigerant system oil lu-
brication will be insufficient and compressor burnout may occur,
so take care to avoid this, necessary care should be taken.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE
WHILE COMPRESSOR IS OPERATING
If the high pressure valves opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close the only low pressure valve.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating etc.

1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Turn the A/C switch ON.
(b) Operating the cooler compressor at the engine rpm of approx. 1,000 for 5 to 6 min., circulate the refrig-
erant and collect compressor oil remaining in each component into the cooler compressor as much
as possible.
(c) Stop the engine.
(d) Let the refrigerant gas out.

Compression Gauge

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).

(c) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 3 camshaft.
NOTICE:
Do not pry out the camshaft.
Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
30. REMOVE NO.4 CAMSHAFT SUB-ASSY
(a) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 4 camshaft.
NOTICE:
Do not pry out the camshaft.
Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
(b) Remove the oil seal from the No. 4 camshaft.
31. INSPECT CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise on the hexagonal lobe.
(b) Check that the VVT-i will not turn.
(c) Cover all the oil ports with vinyl tape except the port on the
advance angle side (nearest to the convex portion)
shown in the illustration.
(d) Using the air gun, apply about 100 kPa (1 kgf/cm
2, 14 psi)
of air pressure to the port on the advance angle side.
NOTICE:
Some oil spraying will occur. Be prepared to catch the
spray with a shop rag.
HINT:
This operation releases the lock pin for the most retard angle
lock.
(e) Under the condition above, turn the VVT-i to the advance
angle side (the direction of the white arrow in the illustra-
tion) by hand.
Standard: Must turn
HINT:
Depending on the air pressure, the VVT-i will turn to the ad-
vance angle side without applying force by hand. Also, if the
pressure can be hardly applied because of the air leakage from
the port, the lock pin might not be released easily.
