ADD ENGINE COOLANT
Tighten the radiator drain cock plug by hand.
Tighten the 2 cylinder block drain cock plugs.
Remove the reserve tank cap. (*1)
Loosen the air drain cock plug on the water inlet housing.
Add TOYOTA Super Long Life Coolant (SLLC).
| Standard capacity |
|---|
| 10.6 liters (11.2 US qts, 9.3 Imp. qts) |
Note
Never use water as a substitute 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).
Squeeze the No. 1 and No. 2 radiator hoses several times. If the coolant level at the water inlet opening drops, add TOYOTA SLLC.
Add TOYOTA SLLC to the reserve tank until coolant overflows from the air drain cock plug hole. Then tighten the air drain cock plug on the water inlet housing.
Continue adding TOYOTA SLLC until it reaches the B line. (*2)
Install the reserve tank cap. (*3)
Run the engine at about 2000 rpm to warm it up until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. (*4)
CAUTION:
When push the radiator hoses, wear protective gloves.
Be careful as the radiator hoses, engine and radiator are hot.
Keep your hands away from the radiator fans.
Note
If the radiator reserve tank runs out of coolant just after the engine is started, stop the engine immediately, wait until the coolant has cooled down, and then add coolant.
Make sure that the reserve tank still has some coolant in it.
If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.
If there is not enough coolant, the engine may overheat or be seriously damaged.
Tech Tips
If coolant comes out from the bypass hose port connected to the reserve tank, the thermostat has been opened.
After the thermostat has opened, idle the engine until the coolant in the reserve tank goes from being cloudy to a clear red.
Stop the engine and wait until the coolant cools down. (*5)
Check that the coolant level is between the FULL and LOW lines. (*6)
Tech Tips
If the coolant level is below the LOW line, repeat steps from (*1) to (*6).
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.
ADD AUTOMATIC TRANSAXLE FLUID
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here
CHARGE WITH REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge with refrigerant HFC-134a (R134a).
| w/o No. 2 Air Conditioning Tube |
|---|
| 780 to 880 g (27.5 to 31.0 oz.) |
| w/ No. 2 Air Conditioning Tube |
| 700 to 800 g (24.7 to 28.2 oz.) |
Note
Do not turn the A/C switch on before charging with refrigerant. Doing so will cause the compressor to work without refrigerant, resulting in overheating of the compressor.
Approximately 200 g (7.1 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by quantity, not with the sight glass.
Tech Tips
Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an A/C system.
WARM UP ENGINE
Keep the A/C switch on for at least 2 minutes to warm up the compressor.
Note
Be sure to warm up the compressor when turning the A/C switch on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
INSPECT FOR REFRIGERANT LEAK
After recharging with refrigerant, inspect for refrigerant leaks using a halogen leak detector.
Carry out the test under the following conditions:
Turn the engine switch off.
Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust gas).
Repeat the test 2 or 3 times.
Make sure that there is some refrigerant remaining in the refrigeration system.
When the compressor is off: approx. 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines.
Bring the halogen leak detector close to the drain hose with the detector's power off, and then turn the detector on.
Tech Tips
After the blower motor has stopped, let the cooling unit stand for more than 15 minutes.
Bring the halogen leak detector sensor under the drain hose.
When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow testing.
If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.
Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
INSPECT FOR COOLANT LEAK
Remove the radiator reservoir cap.
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.
Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.
Warm up the engine.
Pump the radiator cap tester to 118 kPa (1.2 kgf/cm2, 17 psi), and then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks.
If there are no signs of external coolant leaks, check the heater core, cylinder block and head.
Reinstall the radiator reservoir cap.
