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 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.
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.

Use of improper coolants may damage engine cooling
system.

Use ºToyota Long Life Coolantº or equivalent and mix it
with plain water according to the manufacturer's instruc-
tion.

Using of coolant which 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 %.
(c) Tighten the air bleed valve securely.
(d) Install the radiator cap securely.
(e) Warm up the engine.
HINT:
Warm up the engine with the speed of 2,000 rpm or more and
keep the warm±up until the thermostat has open and the radia-
tor reservoir has become hot.
(f) Run the engine intermittently for 5 seconds at 3,000 rpm
and for 45 seconds at idle.
(g) Do the above operation for 7 minutes or more.
(h) After the engine has become cold, check that the coolant
level is between LOW and FULL lines.
