The thermostat open timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.

NOTICE:

When squeezing the radiator hose:

Wear protective gloves.

Be careful as the radiator hoses are hot.

Keep your hands away from the radiator fan.

Maintain the engine speed at 2,000 to 2,500 rpm.

Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system.

NOTICE:

When squeezing the radiator hoses:

Wear protective gloves.

Be careful as the radiator hoses are hot.

Keep your hands away from the radiator 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 the coolant level in the reserve tank.

If the coolant level is low, add coolant to the reserve tank FULL line.

Engine Assembly - Installation. 2AD-FHV ENGINE MECHANICAL. Lexus IS250 IS220d GSE20 ALE20

NOTICE:

Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.

Approximately 100 g (3.53 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.

81. CHECK FOR CLUTCH FLUID LEAKS

NOTICE:

Before performing each inspection, turn the A/C switch off.

Fill the radiator with coolant and attach a radiator cap tester.

Warm up the engine.

Using a radiator cap tester, increase the pressure inside the radiator to 177 kPa (1.8 kgf/cm, 26 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.

84. CHECK FOR FUEL LEAKS

PERFORM ACTIVE TEST

Connect the intelligent tester to the DLC3.

Turn the engine switch ON (IG).

85. CHECK FOR EXHAUST GAS LEAKS

86. CHECK FOR REFRIGERANT LEAKS

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

Stop the engine.

Secure good ventilation (the gas leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).

Repeat the test 2 or 3 times.

Make sure that some refrigerant remains in the refrigeration system. When compressor is off: approximately 392 to 588 kPa (4 to 6 kgf*cm² 57 to 85 psi)

Using a gas 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 gas leak detector sensor into the unit and perform the test.

Disconnect the connector and leave the pressure switch on for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
