PROCEDURE
REMOVE UPPER RADIATOR SUPPORT SEAL
Remove the 13 clips and upper radiator support seal.
REMOVE FRONT BUMPER COVER LOWER
REMOVE NO. 1 ENGINE UNDER COVER SUB-ASSEMBLY
DRAIN ENGINE COOLANT
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.
Loosen the radiator drain cock plug.
*1 | Radiator Cap | *2 | Radiator Reservoir |
*3 | Radiator Drain Cock Plug | *4 | Cylinder Block Drain Cock Plug |
Tech Tips
Collect the coolant in a container and dispose of it according to the regulations in your area.
Drain the coolant by removing the radiator cap.
Loosen the cylinder block drain cock plug.
Loosen the cylinder block drain cock plug and drain the coolant from the engine.
Note
If coolant is not drained from the radiator drain cock plug, cylinder block drain cock plugs and radiator reservoir, clogging in the radiator or coolant leakage from the seal of the water pump may result.
ADD ENGINE COOLANT
Tighten the radiator drain cock plug by hand.
Tighten the cylinder block drain cock plug.
Slowly fill the system with engine coolant.

8.6 liters (9.0 US qts, 7.6 Imp. qts) |
Note
Do not substitute plain water for engine coolant.
Tech Tips
Use only 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 (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids.)
New Toyota vehicles are filled with Toyota Super Long Life Coolant. When replacing the coolant, Toyota Super Long Life Coolant (color is pink, premixed ethylene glycol concentration is approximately 50% and freezing temperature is -35°C (-31°F)) is recommended
Slowly pour coolant into the radiator reservoir until it reaches the Full line.
Install the reservoir cap.
Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level. If the coolant level is low, add coolant.
Install the radiator cap.
Start the engine and warm it up until the thermostat opens.
Tech Tips
The thermostat opening timing can be confirmed by pressing the No. 2 radiator hose by hand and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2000 to 2500 rpm.
Note
Make sure that the radiator reservoir still has some coolant in it.
Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
If there is not enough coolant, the engine may burn out or overheat.
Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the F line.
Run the engine at 2000 rpm until the coolant level has stabilized.
Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air.
CAUTION:
Wear protective gloves. Heat areas on the parts may injure your hands.
Be careful as the radiator hoses are hot.
Keep your hands away from the fan.
Stop the engine, and wait until the engine coolant cools down to ambient temperature.
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.
Check that the coolant level is between the Full and Low lines.
If the coolant level is below the Low line, repeat all of the steps above.
If the coolant level is above the Full line, drain coolant so that the coolant level is between the Full and Low lines.
INSPECT FOR ENGINE COOLANT LEAK
INSTALL NO. 1 ENGINE UNDER COVER SUB-ASSEMBLY
INSTALL FRONT BUMPER COVER LOWER
INSTALL UPPER RADIATOR SUPPORT SEAL
Install the upper radiator support seal with the 13 clips.
