   Tech Tips

   
   

   • TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to 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 consists of a combination of low phosphates and organic acids).

   • Please contact your TOYOTA dealer for further details.

   • for Cold Area Specification Vehicles:

     Please contact any authorized TOYOTA dealer or repairer or another duly qualified and equipped professional for further details.

   Note

   Never use water as a substitute for engine coolant.

4. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.

   If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

5. Install the radiator reservoir cap.

6. Using a wrench, install the vent plug.

   Torque:

   2.0 N*m  { 20 kgf*cm, 18 in.*lbf }

7. Bleed air from the cooling system.

   
   

   1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.

   2. Maintain the engine speed at 2500 to 3000 rpm.

   3. Press the inlet and outlet radiator hoses several times by hand to bleed air.

      CAUTION:

      When pressing the radiator hoses:

      
      

      • Wear protective gloves.

      • Be careful as the radiator hoses are hot.

      • Keep your hands away from the radiator fan.

   4. Stop the engine and wait until the coolant cools down to ambient temperature.

      CAUTION:

      Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

8. After the coolant cools down, check that the coolant level is at the FULL line.

   If the coolant level is below the FULL line, add TOYOTA SLLC to the FULL line.

INSTALL NO. 1 ENGINE UNDER COVER SUB-ASSEMBLY

1. Install the No. 1 engine under cover with the 4 bolts.

   Torque:

   29 N*m  { 296 kgf*cm, 21 ft.*lbf }

INSPECT FOR COOLANT LEAK

1. Fill the radiator with coolant and attach a radiator cap tester.

2. Warm up the engine.

3. Using the radiator cap tester, increase the pressure inside the radiator to 123 kPa (1.3 kgf/cm², 18 psi), and check that the pressure does not drop.

   If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.

INSTALL UPPER RADIATOR SUPPORT SEAL

1. Install the upper radiator support seal with the 13 clips.
