PROCEDURE
DRAIN ENGINE COOLANT
CAUTION:
To avoid the danger of being burned, do not remove the reservoir cap sub-assembly while the engine assembly and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.
*1 | Engine Under Cover LH |
*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.
*1 | Reservoir Cap Sub-assembly |
*2 | Radiator Drain Cock Plug |
*3 | Water Filler Cap Sub-assembly |
*4 | Radiator Reservoir Assembly |
Loosen the radiator drain cock plug.
Remove the water filler cap sub-assembly and 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
CAUTION:
To avoid the danger of being burned, do not remove the reservoir cap sub-assembly while the engine assembly and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.
*1 | Reservoir Cap Sub-assembly |
*2 | Radiator Drain Cock Plug |
*3 | Water Filler Cap Sub-assembly |
*4 | Radiator Reservoir Assembly |
Remove the reservoir cap sub-assembly and water filler cap sub-assembly.
*a | FULL Line |
*b | LOW Line |
Add engine coolant to the radiator reservoir assembly filler opening until it is filled to the FULL line at shown in the illustration.
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 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).
Install the reservoir cap sub-assembly.
Add engine coolant to the radiator hose sub-assembly until it is filled, and then install the water filler cap sub-assembly.
Note
Coat the O-ring of the water filler cap sub-assembly with engine coolant.

5.4 liters (5.7 US qts, 4.8 Imp. qts) |
Squeeze the radiator hose sub-assembly and No. 2 radiator hose sub-assembly several times by hand, and then check the level of the engine coolant.
If the engine coolant level is low, add engine coolant.
Set the air conditioning as follows.
Item | Condition |
---|---|
Fan speed | Any setting except off |
Temperature | Toward WARM |
Air conditioning switch | Off |
Start the engine and warm it up until the engine coolant level of the radiator reservoir assembly has stabilized.
CAUTION:
Wear protective gloves. Hot areas on the parts may injure your hands.
Be careful of the fan.
Be careful as the engine, radiator assembly and radiator hoses are hot and can cause burns.
Note
Perform the engine speed with 2000 rpm or less.
Make sure that the radiator reservoir assembly still has some engine coolant in it.
After starting the engine, if the radiator reservoir assembly does not have any 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 engine coolant is filled to the B line.
If there is not enough engine coolant, the engine may burn out or overheat.
Pay attention to the needle of the engine coolant temperature meter. Make sure that the needle does not show an abnormally high temperature.
Tech Tips
Press the radiator hose sub-assembly and No. 2 radiator hose sub-assembly several times by hand to bleed air while warming up the engine.
The thermostat opening timing can be confirmed by pressing the No. 2 radiator hose sub-assembly by hand and checking when the engine coolant starts to flow inside the hose.
Stop the engine and wait until the engine coolant cools down to ambient temperature.
Check that the engine coolant level is between the FULL and LOW line.
If the engine coolant level is below the LOW line, fill engine coolant into the radiator reservoir assembly until it reaches the FULL Line.
If the engine coolant level is above the FULL line, drain engine coolant so that the engine coolant level is between the FULL and LOW line.
