Coolant: Service and Repair

COOLANT 

REPLACEMENT 

CAUTION:  Be sure that the ignition is off if you work near the electric cooling fans or radiator grille. With the ignition on the electric cooling fans may
automatically start to run if the engine coolant temperature is high and/or the air conditioning is on.

1. DRAIN ENGINE COOLANT

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

(a)

Loosen the radiator drain cock plug.

(b) Remove the radiator cap sub-assembly.
(c)

Loosen the cylinder block drain cock plug, then drain the coolant.

2. ADD ENGINE COOLANT 

(a)

Tighten all the plugs.

(b) Pour engine coolant into the radiator assembly until it overflows.

Capacity:
M/T 4.8 liters (5.1 USqts, 4.5 Imp. qts) 
A/T 4.7 liters (5.0 USqts, 4.4 Imp. qts) 

NOTICE:  Do not substitute water for engine coolant. 

HINT:  
^

Use of improper engine coolant may damage the engine coolant system.

^

Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and
non-borate engine 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).

(c)

Check the engine coolant level inside the radiator assembly by squeezing the inlet and outlet radiator hoses several times by hand. If the
engine coolant level goes down, add engine coolant.

(d) Install the radiator cap sub-assembly securely.
(e)

Slowly pour engine coolant into the radiator reservoir until it reaches the FULL line.

(f)

Warm up the engine until the cooling fan operates.
(1) Set the air conditioning as follows while warming up the engine.
