  1. DRAIN ENGINE COOLANT 
    1. Remove the radiator cap.
      CAUTION: Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
    2. Drain engine coolant by loosening the radiator drain plug and the engine's water drain plug.

      HINT:

      Engine coolant inside the radiator is drained from the drain hole located on the bottom of the engine under cover.

    3. Tighten the cylinder block drain cock plugs.

      Torque: 13 N.m (130 kgf.cm, 10 ft.lbf)

  2. ADD ENGINE COOLANT 
    1. Tighten the radiator drain plug.
    2. Add engine coolant into the radiator until it overflows.

      Capacity: 6.2 liters (6.6 US qts, 5.4 lmp. qts) 

      HINT:

      • Use of improper coolants may damage the engine cooling system.
      • Use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life 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.
      • 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.
      NOTE: Do not use plain water alone.
    3. Pour coolant into the radiator reservoir tank until the coolant reaches the full line.
    4. Install the radiator cap.
    5. Start the engine and run the engine for 10 seconds.
    6. Remove the radiator cap after 10 seconds. Pour coolant if the coolant level is lower.
    7. Repeat (d) to (f) until the coolant level remains the same from steps (d) to (f).

      HINT:

      Perform the procedures above before the engine warms up. A warmed up engine causes the thermostat valve to open, and the air inside of the engine circulates between the radiator and the engine.

    8. Install the radiator cap.
    9. Warm up the engine until the thermostat valve begins to open.

      HINT:

      As the engine warms up, press the radiator inlet and outlet hose several times by hand.

    10. Stop the engine and wait until the coolant cools down to room temperature. If the coolant is below the full line, add coolant.
    11. Install the radiator cap and check the radiator reservoir tank coolant level. If it is below the full line, add coolant.
  3. CHECK FOR ENGINE COOLANT LEAKS 
    1. Fill the radiator with coolant and attach a radiator cap tester.
    2. Pump it to 118 kPa (1.2 kgf/cm2 , 17.1 psi) and check leakage.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
