REPLACEMENT
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.
3. CHECK FOR ENGINE COOLANT LEAKS
4. CHECK ENGINE COOLANT SPECIFIC GRAVITY COR-
RECTLY
