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 is a combination of low phosphates and organic acids).
Slowly pour coolant into the radiator reserve tank assembly until it reaches the full line.

The thermostat open timing can be confirmed by squeezing the No. 2 radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2500 to 3000 rpm.
Squeeze the No. 1 and No. 2 radiator hoses several times by hand to bleed air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the cooling fans.
Note
Make sure that the radiator reserve tank assembly 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.
If the radiator reserve tank assembly does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reserve tank assembly is filled to the full line.
Stop the engine and wait until the engine coolant cools down.
Add engine coolant to the full line on the radiator reserve tank assembly.

| *g | Mean value in proper range | *h | Overcharged |
| Standard charge amount |
|---|
| 450 to 550 g (15.9 to 19.4 oz.) |
Note
Do not turn the A/C switch on before charging the air conditioning system with refrigerant. Doing so may cause the compressor to work without refrigerant, resulting in overheating of the compressor.
The refrigerant amount should be checked by quantity (weight).
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 air conditioning system.
WARM UP ENGINE
INSPECT FOR FUEL LEAK

Inspect for fuel leaks.
Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.
Turn the ignition switch off.
Disconnect the intelligent tester from the DLC3.
INSPECT FOR OIL LEAK
INSPECT FOR COOLANT LEAK
Note
Before performing each inspection, turn the A/C switch off.

Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 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 cylinder head.
INSPECT FOR EXHAUST GAS LEAK
INSPECT REFRIGERANT LEAK
After recharging the air conditioning system with refrigerant, check for refrigerant leaks using a halogen leak detector.
Carry out the test under the following conditions:
Turn the engine switch off.
Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.
Pressure when the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)
Ensure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).

How to check for refrigerant leaks in pipe joints:
Note
Gas leaking from a joint can be dissipated by even the slightest breeze. Move the halogen leak detector sensor 360° around each joint instead of keeping it in one spot when checking.
Using a halogen leak detector, check for refrigerant leaks at the pipe joints shown in the illustration.
| *a | Area to be Checked | *b | Service Valve (High) |
