COOLING SYSTEM (3MZ-FE)
ON-VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
(a) Remove the water outlet cap.
CAUTION:
To avoid the danger of being burned, do not remove the wa-
ter outlet cap while the engine and radiator are still hot.
Thermal expansion will cause hot engine coolant and
steam to blow out from the radiator.
(b) Fill the radiator with coolant, then attach a radiator cap
tester.
(c) Warm up the engine.
(d) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), then check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator and water
pump for leaks. If there are no signs or traces of external coolant
leaks, check the heater core, cylinder block and head.
(e) Reinstall the water outlet cap.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant should be between the ºLOWº and ºFULLº lines when the engine is cold.
If low, check for leaks and add ºToyota Super Long Life Coolantº or similar high quality ethylene glycol based
non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology
up to the ºFULLº line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the water outlet cap.
CAUTION:
To avoid the danger of being burned, do not remove the water outlet cap while the engine and radiator
are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
(b) Check if there are any excessive deposits of rust or scale around the water outlet cap and water outlet
filler hole; the coolant should free of oil.
If excessively dirty, replace the coolant.
(c) Reinstall the water outlet cap.
