ON–VEHICLE INSPECTION
1.
INSPECT COOLING SYSTEM FOR LEAKS
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.
(a)
Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b)
Warm up the engine.
(c)
Pump it to 118 kPa (1.2 kgf/cm
2
, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check to hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
2.
CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a)
The engine coolant level should be between the ”LOW” and ”FULL” lines, when the engine is cold.
If low, check for leaks and add ”Toyota Long Life Coolant” or equivalent up to the ”FULL” line.
3.
CHECK ENGINE COOLANT QUALITY
(a)
Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b)
Check if there is any excessive deposits of rust or scale around the radiator cap and radiator filler hole;
the coolant should be free from oil.
HINT:
If excessively dirty, replace the coolant.
(c)
Reinstall the radiator cap.
