2. DRAIN ENGINE COOLANT
CAUTION:
*1 | Reserve Tank Cap | *2 | Radiator Drain Cock Plug |
(a) Connect a hose with an inside diameter of 9 mm (0.354 in.) to the radiator drain cock as shown in the illustration. |
|
(b) Loosen the radiator drain cock plug.
(c) Remove the reserve tank cap. Then drain the engine coolant. HINT: Collect the engine coolant in a container and dispose of it according to the regulations in your area. |
|
(d) Tighten the radiator drain cock plug by hand.
(e) Disconnect the hose from the radiator drain cock.
3. ADD ENGINE COOLANT
(a) Using a 6 mm hexagon socket wrench, remove the air release valve from the radiator reserve tank assembly. |
|
(b) Add engine coolant to the level shown in the illustration. Standard Capacity: 5.2 liters (5.5 US qts, 4.6 Imp. qts) NOTICE: Do not substitute plain water for engine coolant. HINT: 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). | |
(c) Using a 6 mm hexagon socket wrench, install the air release valve to the radiator reserve tank assembly.
Torque:
2.0 N·m {20 kgf·cm, 18 in·lbf}
(d) Install the reserve tank cap.
NOTICE:
Securely tighten the reserve tank cap as much as possible.
(e) Bleed air from the cooling system.
NOTICE:
(1) Warm up the engine until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes.
HINT:
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:
NOTICE:
HINT:
If the flowing sound of engine coolant can still be heard after bleeding air, perform the following procedure to bleed air again.
(f) After the engine has cooled down, check that the engine coolant level is between the MAX and MIN lines. NOTICE: The engine coolant levels in the compartments inside the radiator reserve tank assembly may differ, but this is not a malfunction. If the engine coolant level is below the MIN line, add engine coolant to the MAX line. |

The front and side supplemental restraint systems (SRS) include different types of air bags. Please verify the different types of air bags which are equipped on your vehicle by locating the “SRS AIRBAG” location indicators. These indicators are visible in the area where the air bags are installed.
The air bags are installed in the following locations:
The steering wheel hub (driver air bag) The front passenger dashboard (front passenger air bag) The outboard sides of the front seatbacks (side air bags) The front and rear window pillars, and the roof edge along both sides (curtain air bags)
