HINT:

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.

NOTICE:

1. Make sure that the radiator reservoir still has some coolant in it.
   
2. Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
   
3. If there is not enough coolant, the engine may burn out or overheat.
   
4. 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.
   
5. 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:

1. Wear protective gloves. Hot areas on the parts may injure your hands.
   
2. Be careful as the radiator hoses are hot.
   
3. 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 F and L lines.
If the coolant level is below the L line, repeat all of the procedures above.
If the coolant level is above the F line, drain coolant so that the coolant level is between the F and L lines.

Make sure that there are no fuel leaks after performing maintenance on the fuel system.

NOTICE:

Be sure to warm up the compressor when turning the A/C switch is on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.

After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.

Perform the operation under these conditions:

1. Stop the engine.
   
2. Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).
   
3. Repeat the test 2 or 3 times.
   
4. Make sure that some refrigerant remains in the refrigeration system. When compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm², 57 to 85 psi).
   

Using a halogen leak detector, check the refrigerant line for leakage.

If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.

Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.

2. See the table below for possible causes, and then inspect and correct the corresponding causes if necessary.
   
   

   CO	HC	Symptom	Causes
   Normal	High	Rough idling	Faulty ignition: Incorrect timing Plugs are contaminated or shorted, or plug gaps are incorrect Incorrect valve clearance Leaky intake and exhaust valves Leaky cylinders
   Low	High	Rough idling (Fluctuating HC reading)	Vacuum leaks: Ventilation hoses Intake manifold Throttle body Lean mixture causing misfire
   High	High	Rough idle (Black smoke from exhaust)	Restricted air filter Plugged PCV valve Faulty SFI system: Faulty pressure regulator Defective engine coolant temperature sensor Faulty mass air flow meter Faulty ECM Faulty injectors Faulty throttle position sensor

The engine coolant should be between the L and F lines when the engine is cold.
If the engine coolant is below the L line, check for leakage and add TOYOTA Super Long Life Coolant (SLLC) or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology to the F line.

NOTICE:

Do not substitute plain water for engine coolant.
