PROCEDURE

DRAIN ENGINE COOLANT

CAUTION:

Do not remove the reserve tank cap or radiator drain cock plug while the engine and radiator assembly are still hot. Pressurized hot engine coolant and steam may be released and cause serious burns.

*1 No. 1 Engine Under Cover

*a Hose

Connect a hose with an inside diameter of 9 mm (0.354 in.) to the radiator drain cock as shown in the illustration.

Loosen the radiator drain cock plug.

*1	Radiator Drain Cock Plug	*2	Reserve Tank Cap
*3	Air Drain Cock Plug	-	-

Remove the reserve tank cap. Then drain the engine coolant.

Tech Tips

Collect the engine coolant in a container and dispose of it according to the regulations in your area.
Tighten the radiator drain cock plug by hand.
Disconnect the hose from the radiator drain cock.

ADD ENGINE COOLANT

*1	Air Drain Cock Plug
*a	Hose
*b	Container

Connect a hose with an inside diameter of 7 mm (0.276 in.) to the air drain cock plug as shown in the illustration.

Tech Tips

Use a container to catch the draining engine coolant.

Loosen the air drain cock plug.
Add engine coolant to the intercooler reserve tank assembly until engine coolant overflows from the air drain cock hole. Then tighten the air drain cock plug.

Torque:

1.0 N*m { 10 kgf*cm, 9 in.*lbf }
Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the level of the engine coolant.

If the engine coolant level is low, add engine coolant.

Add engine coolant to the level shown in the illustration.

Standard Capacity

Item	Specified Condition
for CVT	6.4 liters (6.8 US qts, 5.6 Imp. qts)
for Manual Transaxle	6.2 liters (6.6 US qts, 5.5 Imp. qts)

Note

Do not substitute plain water for engine coolant.

Tech Tips

TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damaging the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids).

Install the reserve tank cap.

Note

Securely tighten the reserve tank cap as much as possible.
Bleed air from the cooling system.
Note
- Before starting the engine, turn the A/C switch off.
- Adjust the heater control to the maximum hot setting.
- Adjust the blower speed to the low setting.
1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes.
  
  Tech Tips
  
  The thermostat open timing can be confirmed by squeezing the No. 2 radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the No. 2 radiator hose.
2. After the engine has warmed up, run the engine using the following cycle for at least 7 minutes: at 3000 rpm for 5 seconds, at idle speed for 45 seconds. (Repeat this cycle at least 8 times.)
3. Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand to bleed air from the system.
  CAUTION:
  When squeezing the No. 1 radiator hose and No. 2 radiator hose:
  - Wear protective gloves.
  - Be careful as the No. 1 radiator hose and No. 2 radiator hose are hot.
  - Keep your hands away from the fan and No. 2 fan.
  Note
  - If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.
  - Make sure that the intercooler reserve tank assembly still has some engine coolant in it.
  - If the intercooler reserve tank assembly does not have enough engine coolant, the engine may overheat or be seriously damaged.
  - If the intercooler reserve tank assembly does not have enough engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant until the intercooler reserve tank assembly is filled to the full line.
  Tech Tips
  
  If the flowing sound of engine coolant can still be heard after bleeding air, perform the following procedure to bleed air again.
  1. Warm up the engine. (With the engine idling, check that the engine coolant is flowing into the intercooler reserve tank assembly.)
  2. Run the engine at 2000 rpm for 2 minutes or more. (A)
  3. Leave the engine idling for 2 minutes or more. (B)
  4. Repeat steps (A) and (B) 4 times or more.
After the engine has cooled down, check that the engine coolant level is between the full and low lines.

If the engine coolant level is below the low line, add engine coolant to the full line.
