1986 TOYOTA CAMRY V20 engine coolant

(d) To release the air, loosen the union bolt of the water out-
let five revolutions.
(e) Slowly fill the system with coolant.
Use a good brand of ethylene±glycol base coolant,
mixed according to the manufacturer's directions.
Capacity (w/ Heater):
M/T 9.5 liters (10.0 US qts, 8.4 Imp. qts)
A/T 9.4 liters (9.9 US qts, 8.3 Imp. qts)
(f) Tighten the union bolt of the water outlet.
Torque: 180 kg±cm (13 ft±Ib, 18 N±m)
(g) Install the radiator cap.
(h) Start the engine and check for leaks.
(i) Recheck the coolant level and refill as necessary.
HINT: When the coolant has been depleted, refill with
coolant and repeat steps (d) to (i). 4. (2VZ±FE)
REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not re-
move it while the engine and radiator are still hot as fluid
and steam can be blown out under pressure.
(b) Drain the coolant from the radiator and engine drain cocks.
(Engine drain cocks are at the front center and rear right
of the cylinder block.)
(c) Close the drain cocks.
Torque (Engine drain cock):
300 kg±cm (22 ft±Ib, 29 N±m)
NOTICE:
wDo not use alcohol type coolant.
wThe coolant should be mixed with demineralized
water or distilled water.
Capacity (w/ Heater).
M/T 6.4 liters (6.8 US qts, 5.6 Imp. qts)
A/T (2WD) 6.3 liters (6.7 US qts, 5.5 Imp. qts)
A/T (4WD) 6.8 liters (7.2 US qts, 6.0 Imp. qts)
(e) Install the radiator cap.
(f) Start the engine and check for leaks.
(g) Recheck the coolant level and refill as necessary. (d) Fill the system with coolant.
Use a good brand of ethylene±glycol base coolant, mixed
according to the manufacturer's directions.
Using coolant which includes more than 5O%
ethylene±glycol (but less than 70%) is recommended.

HINT: The thermostat is numbered with the valve opening
temperature.
(a) Immerse the thermostat in water and gradually heat the wa-
ter.
(b) Check the valve opening temperature.
Valve opening temperature:
80 ± 845C (176 ± 1835F)
If the valve opening temperature is not as specified, re-
place the thermostat.
(e) Check the valve lift.
Valve lift:
8 mm (0.31 in.) or more at 95°C (203°F)
If the valve lift is less than specification, replace the
thermostat.
INSTALLATION OF THERMOSTAT
