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.

LUBRICATION SYSTEM (3MZ-FE)
ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine, then stop the engine and wait for 5 minutes.
(b) Check that the engine oil level is between the low and full level marks on the level gage.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloring
or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
Use API grade SL ºEnergy-Conservingº, or ILSAC
multigrade engine oil.
SAE 5W-30 is the best choice for good fuel economy,
and good starting in cold weather.
If SAE 5W-30 is not available, SAE 10W-30 may be
used.
However, it should be replaced with SAE 5W-30 at the
next oil replacement.
3. INSPECT OIL PRESSURE
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24 mm, remove the oil pres-
sure switch.
(c) Install the oil pressure gauge.
(d) Warm up the engine.
(e) Inspect the oil pressure.
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm245 to 539 kPa (2.5 to 5.5 kgf/cm2, 36 to 78 psi)

(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the electrode
with a spark plug cleaner, then dry it.
Air pressure: Blow 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or shorter
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
2. INSPECT VVT SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance:
Tester ConnectionSpecified Condition
1 (G+) - 2 (G-)835 to 1,400 W at cold
1 (G+) - 2 (G-)1,060 to 1,645 W at hot
NOTICE:
ºColdº and ºHotº mean temperature of the coils them-
selves. ºColdº is from -10C (14F) to 50C (122F) and
ºHotº is from 50C (122F) to 100C (212F).
If the resistance is not as specified, replace the VVT sensor.
3. INSPECT CRANKSHAFT POSITION SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance:
Tester ConnectionSpecified Condition
1 (NE+) - 2 (NE-)1,630 to 2,740 W at cold
1 (NE+) - 2 (NE-)2,065 to 3,225 W at hot
NOTICE:
ºColdº and ºHotº mean temperature of the coils them-
selves. ºColdº is from -10C (14F) to 50C (122F) and
ºHotº is from 50C (122F) to 100C (212F).
If the resistance is not as specified, replace the crankshaft posi-
tion sensor.
