Coolant: Service and Repair

COOLANT 

REPLACEMENT 

1. DRAIN ENGINE COOLANT

CAUTION:  To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal
expansion will cause hot engine coolant and steam to blow out from the radiator.
 

a. Remove the service hole cover from the engine undercover.
b. Install a vinyl hose onto the drain on the radiator side.
c. Fix the vinyl hose with tape.

d. Loosen the 3 drain plugs on the engine and radiator, and drain the coolant.
e. Remove the radiator cap.
f.

Drain the coolant from the reservoir tank.

g. Tighten the 3 drain plugs. 

Torque: 13 Nm (130 kgf-cm, 9 ft. lbs.) for the engine

h. Remove the vinyl hose from the radiator.

2. ADD ENGINE COOLANT

a. Pour coolant into the radiator until it overflows.

Capacity

HINT:  
^

Use of improper coolants may damage the engine cooling system.

^

Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based nonsilicate, non-amine, non-nitrite, and
non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a
combination of low phosphates and organic acids).

^

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 -35°C (-31°F)). When replacing the coolant, Toyota Super Long Life Coolant is
recommended.

NOTICE:  Do not substitute plain water for engine coolant.

b. Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand. If the coolant level goes

down, add coolant.

c. Install the radiator cap securely.
