1. DRAIN ENGINE COOLANT
a. Remove the reservoir cap.

CAUTION: To avoid the danger of being burned, do not remove the reservoir cap while the engine and radiator are still hot, as fluid and steam can be blown out under pressure.

b. Loosen the radiator drain plug (in the left under side of the radiator tank) and engine drain plug on the engine coolant drain union (on the left rear of the cylinder block), and drain the coolant.
c. Close the drain plugs.
Torque: 12.7 Nm (130 kgf-cm, 9 ft. lbs.) for engine
2. FILL ENGINE COOLANT
a. Remove the upper front fender apron seal and upper radiator support seal.





b. Remove the 2 bolts.
c. Disconnect the 3 clamps and 2 hoses, then place hoses on air cleaner case.

NOTICE: Do not use plain water alone.

HINT:
- Use of improper coolants may damage the engine cooling system.
- Use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based nonsilicate, nonamine, nonnitrite, and nonborate coolant with longlife 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 35°C (31°F)). When replacing the coolant, Toyota Super long Life Coolant is recommended.

DO NOT FURTHER DILUTE PRE-MIXED MANUFACTURER APPROVED ETHYLENE GLYCOL BASED COOLANT IF USED.

- 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.
- When the level can not be lowered before the supply of the 3.7 liters coolant, squeeze the radiator lower hose several times while blocking the hole in the bleeder plug with a finger, and surely supply the coolant.

g. Start the engine with the reservoir cap and the bleeder plug removed and warm it up until the cooling fan blows first and then stops.

HINT: At this time, the A/C switch should be OFF.

h. Additionally supply 500 cc coolant with the engine idling.
i. Install the bleeder plug and reservoir cap.

HINT: Close the reservoir cap by marking approximately 2.5 rotations until clicks is heard.

j. Repeat 5 sec. engine operation at 3,000 rpm and 5 sec. idling alternately for 15 min. or more.
k. After complete cooling of the engine, the level shall be between Low and FULL.

HINT: After warming-up of engine, the level shall be over the FULL.

l. Connect the 2 hoses and clamps.
m. Install the 2 bolts.
n. Install the cover.
3. CHECK FOR COOLANT LEAKS
4. CHECK ENGINE COOLANT SPECIFIC GRAVITY CORRECTLY
