ENGINE COOLANT (3MZ-FE)
REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the water outlet cap from the water outlet.
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) Loosen the radiator drain plug and 2 drain cock plugs,
then drain the coolant.
(c) Close the radiator drain plug.
(d) Tighten the 2 drain cock plugs.
Torque: 13 NVm (130 kgfVcm, 9 ftVlbf)
2. ADD ENGINE COOLANT
(a) Slowly fill the cooling system with coolant.
Capacity: 9.2 liters (9.7 US qts, 8.1 lmp. qts)
HINT:
Use of improper coolants may damage the engine cooling system.
Use 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.
New Toyota vehicles are filled with Toyota Super Long Life Coolant (color is pink, premixed ethylene-
glycol concentration is approximately 50% and freezing temperature is -35C (-31F)). When replac-
ing the coolant, Toyota Super Long Life Coolant is recommended.
Observe the coolant level inside the radiator by pressing the inlet and outlet radiator hoses several
times by hand. If the coolant level goes down, add the coolant.
NOTICE:
Do not use plain water alone.
3. CHECK FOR ENGINE COOLANT LEAKS
(a) Fill the radiator with coolant, then attach a radiator cap tester.
(b) Pump it to 118 kPa (1.2
kgf/cm2
17.1 psi), then check for leakage.
