coolant TOYOTA CAMRY V20 1986 Service Information

3. (3S±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 cock at the right rear of engine block.)
(c) Close the drain cocks.
Torque (Engine drain cock):
130 kg±cm (9 ft±Ib, 13 N±m) HINT: If the engine tends to overheat, removal of the
thermostat will adversely effect cooling efficiency.
CHECK AND REPLACEMENT OF
ENGINE COOLANT
1. CHECK ENGINE COOLANT LEVEL AT RESERVE TANK
The coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add coolant up to the ºFULLº
line.
Dirt, leaves or insects on radiator or condenser
Hoses, Water pump, thermostat housing, radiator,
heater, core, plugs or head gasket leakage
Thermostat faulty
Incorrect ignition timing
Electric cooling system faulty
Radiator hose plugged or rotted
Water pump faulty
Radiator plugged or cap faulty
Cylinder head or block cracked or water passage
clogged
2. CHECK ENGINE COOLANT QUALITY
There should not be any excessive deposits of rust or scales
around the radiator cap or radiator filler hole, and the cool-
ant should be free from oil.
If excessively dirty, replace the coolant.
Check thermostat
Reset tinning
Inspect electric cooling system
Replace hose
Replace water pump
Check radiator and cap

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):
