ANTI-RUST TREATMENT AFTER PAINTING PROCESS
1. ANTI-RUST AGENT (WAX) APPLICATION
To preserve impossible to paint areas from corrosion,
always apply sufficient anti-rust agent (wax) to the
inside of the hemming areas of the doors and hoods,
and around the hinges, or the welded surfaces inside
the boxed cross-section structure of the side mem-
ber, body pillar, etc.
ANTI-RUST AGENT (WAX) APPLICATION
REFERENCE: ANTI-RUST TREATMENT BY PAINTING
Painting prevents corrosion and protects the sheet metal from damage. In this section, anti-chipping paint
only for anti-corrosion purpose is described.
1. ANTI-CHIPPING PAINT
To prevent corrosion and protect the body from damage by flying stones, etc., apply anti-chipping
paint to the rocker panel, wheel arch areas, valance panel, etc.
HINT:
Depending on the model or the application area, there are cases where the application of anti-chip-
ping paint is necessary before the second coat or after the top coat.

Apply the anti-chipping paint
before the second coat.
Apply the anti-chipping paint
after the top coat.

COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines at normal temperature
(20°C(68°F)).
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.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the radiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, clean the coolant passages and replace the coolant.
(c) Reinstall the radiator cap.

1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Remove the 3 drain plugs on the engine and radiator, and
drain the coolant.
(c) Close the 3 drain plugs.
Torque: 12.7 N´m (130 kgf´cm, 9 ft´lbf) for engine
2. REFILL WITH ENGINE COOLANT
(a) Slowly fill the system with coolant.
Capacity:
w/ Front heater: 14.8 liters (15.6 US qts, 13.0 Imp. qts)
w/ Front heater and rear heater:
15.3 liters (16.2 US qts, 13.4 Imp. qts)
NOTICE:
Do not use plain water alone.
HINT:

Use of improper coolants may damage the engine cooling
system.

Use ºToyota Super Long Life Coolantº or similar high qual-
ity ethylene glycol based non-silicate, non-amine, non-
nitrite, and non-borate coolant with long-life hybrid or-
ganic acid technology.

New Toyota vehicles are filled with Toyota Super Long
Life Coolant (color is pink, premixed ethylene glycol con-
centration is approximately 50 % and freezing tempera-
ture is -35°C (-31°F)). When replacing the coolant, Toyo-
ta 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.
If the coolant level goes down, add the coolant.
(b) Install the radiator cap.
(c) Bleed the cooling system.
(1) Start the engine, and open the heater water valve.
(2) Maintain the engine speed at 2,000 - 2,500 rpm,
and warm up the engine.
(d) Stop the engine, and wait until the engine coolant cools
down.
(e) Refill coolant into the reservoir until it is ºFULLº.

ON-VEHICLE CLEANING
INSPECT FINS FOR BLOCKAGE
If fins are clogged, wash them with water or a steam cleaner and
dry with compressed air.
NOTICE:

If the distance between the steam cleaner and the
core is too close, there is a possibility of damaging
the fin, so keep the following injection distance.
Injection PressureInjection Distance
2,942 - 4,903 kpa
(30 - 50 kg/cm2,
427 -711 psi)300 mm (11.811 in)
4,903 - 7,845 kpa
(50 - 80 kg/cm2,

If the fins are bent, straighten them with a screwdriver
or pliers.

Never apply water directly onto the electronic compo-
nents.

ON-VEHICLE INSPECTION
1. REMOVE RADIATOR CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:

If the radiator cap has contaminations, always rinse
it with water.

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

When performing steps (a) and (b) below, keep the
tester at an angle of over 30° above the horizontal.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the radiator cap tester, and measure the relief valve
opening pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Standard opening pressure:
93 - 123 kPa (0.95 - 1.25 kgf/cm
2, 13.5 - 17.8 psi)
Minimum opening pressure:
78 kPa (0.8 kgf/cm
2, 11.4 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP
