REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
(b) Loosen the radiator and engine drain plugs, drain the
coolant.
(c) Close the drain plugs.
Torque: 13 Nm (133 kgfcm, 10 ftlbf) for engine
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.

3. CHECK FOR ENGINE COOLANT LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tester.
(b) Pump it to 137 kPa (1.4 kgf/cm
2,
19.9 psi), and check that the pressure does not drop.

(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
(c) Disconnect the temperature detect switch connector.
(d) Connect the terminals on the temperature detect switch connector.
(e) Check that the cooling fan rotates.
If not, check the fuses, cooling fan relay and cooling fan, and check for a open circuit between the cooling
fan relay and temperature detect switch.
(f) Reconnect the temperature detect switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 93C (199F))
(a) Start the engine, and raise coolant temperature to above 93C (199F)
HINT:
Coolant temperature is the detected value by the temperature detect switch on the radiator lower tank.
(b) Check that the cooling fan rotates.
If not, replace the temperature detect switch.
3. INSPECT COOLING FANS
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage:
Approx. 13.2 A at 20C (68F)
(d) Reconnect the cooling fan connector.
