COOLING SYSTEM (3MZ-FE)
ON-VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
(a) Remove the water outlet cap.
CAUTION:
To avoid the danger of being burned, do not remove the wa-
ter outlet cap while the engine and radiator are still hot.
Thermal expansion will cause hot engine coolant and
steam to blow out from the radiator.
(b) Fill the radiator with coolant, then attach a radiator cap
tester.
(c) Warm up the engine.
(d) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), then check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator and water
pump for leaks. If there are no signs or traces of external coolant
leaks, check the heater core, cylinder block and head.
(e) Reinstall the water outlet cap.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant should be between the ºLOWº and ºFULLº lines when the engine is cold.
If low, check for leaks and add ºToyota Super Long Life Coolantº or similar high quality ethylene glycol based
non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology
up to the ºFULLº line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the water outlet cap.
CAUTION:
To avoid the danger of being burned, do not remove the water outlet cap while the engine and radiator
are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
(b) Check if there are any excessive deposits of rust or scale around the water outlet cap and water outlet
filler hole; the coolant should free of oil.
If excessively dirty, replace the coolant.
(c) Reinstall the water outlet cap.

(b) Check that the belt fits properly in the ribbed grooves.
Confirm that the belt has not slipped out of the groove on the
bottom of the pulley by hand.
5. INSPECT GENERATOR WIRING
(a) Visually check the generator wiring.
(1) Check that the wiring is in good condition.
6. INSPECT ABNORMAL NOISES
(a) Listen to abnormal noises from generator.
(1) Check that no abnormal noise is heard from the generator while the engine is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine, then check that the light goes off.
If the light does not operate as specified, troubleshoot the charge warning light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a tester is not available, connect a voltmeter to the
charging circuit as follows.
(1) Disconnect the wire from terminal B of the genera-
tor, then connect it to the negative (-) lead of the
ammeter.
(2) Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
(3) Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
(4) Ground the negative (-) lead of the voltmeter.
(b) Check the charging circuit.
(1) Keep the engine speed at 2,000 rpm, then check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 to 14.8 V
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high beam headlights ON and turn the heater blower
switch to the ºHIº position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more

If the ammeter reading is less than the standard amperage, repair the generator.

If the battery is fully charged, the indication will sometimes be less than the standard amperage.

Under certain driving conditions, some 2004 and 2005 model year ES 330 vehicles may
exhibit a M.I.L. ªONº with at least one of the following DTCs:
P0031 (Oxygen Sensor Heater Control Circuit Low [Bank 1, Sensor 1])
P0051 (Oxygen Sensor Heater Control Circuit Low [Bank 2, Sensor 1])
P2238 (Oxygen Sensor Pumping Current Circuit Low (for A/F Sensor)
[Bank 1, Sensor 1])
P2241 (Oxygen Sensor Pumping Current Circuit Low (for A/F Sensor)
[Bank 2, Sensor 1])
The A/F sensor manufacturing process and the Engine Control Module (ECM)
(SAE term: Powertrain Control Module/PCM) logic have been modified to improve
these conditions.
NOTE:
Version 12.01a or later Diagnostic Tester software is required to perform
this procedure.
Before proceeding, verify the ECM (PCM) calibration has NOT been updated
by checking for the Authorized Modifications Label (shown in step 2 of the
Repair Procedure).

WHEEL FILM FOR BRAKE ROTOR RUST PREVENTION ± PD001-04 July 16, 2004
Page 2 of 2
Firmly hold the outer end of the wheel film to pull it off.
NOTE:
If film adhesive residue is found on the disc wheel, remove it with a soft
cloth dipped in ethyl alcohol (ethanol). Do not use thinner to remove the
adhesive residue.
When the wheel film is removed below an ambient temperature of 0
C (32
F), it is
possible that the film may tear. For ease of film removal in cold conditions, please
warm the film above 0
C (32
F) using one of the following methods:
± Splash (hot) water on the wheel film.
± Warm wheel film with cotton cloth soaked in hot water.
± Warm wheel film with heat gun. Be sure not to overheat the film and wheel.
± Warm wheel film by infrared heater (lamp) for paint. Be sure not to overheat
the film and wheel.
± Warm wheel film by steam car wash.
± Park vehicle indoors (e.g. garage, etc.) for an extended period of time.
Please follow local laws for disposal. Polyethylene film will not generate harmful gasses
when it is burned.
