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.

INSPECTION
1. INSPECT THERMOSTAT
HINT:
The thermostat is inscribed with the valve opening temperature.
(a) Immerse the thermostat in water, then gradually heat the
water.
(b) Inspect the valve opening temperature of the thermostat.
Valve opening temperature:
80 to 84C (176 to 183F)
If the valve opening temperature is not as specified, replace the
thermostat.
(c) Inspect the valve lift.
Valve lift: 10 mm (0.39 in.) or more at 95C (203F)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve is fully closed when the thermostat
is at low temperature (below 77C (171F)).
If not fully closed, replace the thermostat.
2. INSPECT WATER OUTLET CAP SUB-ASSY
NOTICE:

If the water outlet cap is contaminated, rinse it with
water.

Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.

When performing the following steps (a) and (b), keep
the tester at an angle of over 30 above horizontal.

REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the water outlet cap from the water outlet.
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) Loosen the radiator drain plug and 2 drain cock plugs,
then drain the coolant.
(c) Close the radiator drain plug.
(d) Tighten the 2 drain cock plugs.
Torque: 13 NVm (130 kgfVcm, 9 ftVlbf)
2. ADD ENGINE COOLANT
(a) Slowly fill the cooling system with coolant.
Capacity: 9.2 liters (9.7 US qts, 8.1 lmp. qts)
HINT:

Use of improper coolants may damage the engine cooling system.

Use 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.

New Toyota vehicles are filled with Toyota Super Long Life Coolant (color is pink, premixed ethylene-
glycol concentration is approximately 50% and freezing temperature is -35C (-31F)). When replac-
ing the coolant, Toyota Super Long Life Coolant is recommended.

Observe the coolant level inside the radiator by pressing the inlet and outlet radiator hoses several
times by hand. If the coolant level goes down, add the coolant.
NOTICE:
Do not use plain water alone.
3. CHECK FOR ENGINE COOLANT LEAKS
(a) Fill the radiator with coolant, then attach a radiator cap tester.
(b) Pump it to 118 kPa (1.2
kgf/cm2
17.1 psi), then check for leakage.

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)
