A/TLHD6.3 (6.7, 5.5)
A/TRHD6.4 (6.8, 5.6)
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 ±\
35 C (±31 F)) or 60 %
(freezing protection down to ±50 C (±58 F)) 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.

2. ADD ENGINE COOLANT
(a) Loosen air bleed valve A.
(b) Fill the cooling system with coolant up to line B.
Capacity:
With heater: 7.6 liters (8.0 US qts, 6.7 lmp. qts)
Without heater: 7.4 liters (7.8 US qts, 6.5 lmp. qts)
HINT:

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.

CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot.
Thermal expansion will cause hot engine coolant and
steam to blow out from the radiator.
(a) Remove the radiator cap.
(b) Loosen the radiator drain cock plug and the cylinder block
drain cock plug, and drain engine coolant.
(c) Close the radiator drain cock plug.
(d) Close the cylinder block drain plug.
