ON±VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot. Ther-
mal expansion will cause hot engine coolant and steam to
blow out from the radiator.
(a) Remove the radiator support opening cover.
(b) Remove the engine room cover side.
(c) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(d) Warm up the engine.
(e) Pump it to 137 kPa (1.4 kgf/cm
2, 19.9 psi), and 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.
(f) Reinstall the engine room cover side.
(g) Reinstall the radiator support opening cover.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant should be between the ºLOWº and ºFULLº li\
nes, when the engine is cold.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
3. 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. Thermal expansion will cause hot engine coolant and steam to\
blow out from the radiator.
(b) Check if there is any excessive deposits of rust or scale around the radiator\
cap and radiator filler hole; the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

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.
(f) Reinstall the engine room cover side.
(g) Reinstall the radiator support opening cover.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant level should be between the ºLOWº and ºFULLº\
lines, when the engine is cold.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.

NOTICE:

Do not use an alcohol type coolant or plain water alone.

The coolant should be mixed with plain water (preferably demineralized wat\
er or distilled wa-
ter).
HINT:

Use of improper coolants may damage engine cooling system.

Use ºToyota Long Life Coolantº or equivalent and mix it with plain water ac\
cording to the manufactur-
er's directions.

Using of coolant with includes more than 50 % (freezing protection down to ±\
35C (±31F)) or 60 %
(freezing protection down to ±50C (±58F)) of ethylene±glycol is recommended but not more than
70 %.

Press the radiator inlet and outlet hose several times with hard.

If the coolant level gets lower, pour coolant.
(b)Reinstall the radiator cap.
(c)Pour engine coolant into the reservoir tank until it reaches full line.
(d)Warm up the engine until the thermostat valve begins to open.
HINT:
Press the radiator inlet and outlet hose several times with hard during \
the warming up.
(e)Stop the engine and wait until the coolant temp. Gets cold. Then remove the radiator cap to check the coolant level.
HINT:

If the level gets lower, perform the procedures above again.

If the level does not gets lower, adjust the reservoir tank coolant level.
