COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines, when the engine is cold.
If low, check for leaks and add ''Toyota Long Life Coolantº or Equivalent up to the ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap from the water outlet.
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 water outlet
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 from the water outlet.
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) Loosen the radiator drain plug and engine drain plugs,
and drain the coolant.
(c) Close the drain plugs.
Torque:
RH engine drain plug on cylinder block side cover:
7 N´m (70 kgf´cm, 61 in.´lbf)
LH engine drain plug on union:
13 N´m (130 kgf´cm, 9 ft´lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
Use of improper coolants may damage engine cool-
ing system.
Use ºToyota Long life Coolantº or equivalent and
mix it with plan water according to the manufactur-
er's directions.
Using of coolant which includes more than 50 %
(freezing protection down to -35°C (-31°F) or 60 %
(freezing protection down to -50°C (-58°F)) of eth-
ylene-glycol is recommended but not more than 70
%.
NOTICE:
Do not use an alcohol type coolant or plain water
alone.
The coolant should be mixed with plain water (prefer-
ably demineralized water or distilled water).
Capacity: 9.0 liters (9.5 US qts, 7.9 lmp. qts)
(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) If necessary, refill coolant into the reservoir up to the
ºFULLº line.
