| Номинальный объем |
|---|
| 8,6 литра (9,0 кварты США, 7,6 английской кварты) |
Note
Не доливайте простую воду вместо охлаждающей жидкости двигателя.
Tech Tips
Разрешается использовать только охлаждающую жидкость "Toyota Super Long Life Coolant" или аналогичную высококачественную охлаждающую жидкость на основе этиленгликоля (но не на силикатной, аминовой, нитритной или борнокислой основе), изготовленную по гибридной технологии органических кислот с длительным сроком годности (охлаждающая жидкость, изготовленная по гибридной технологии органических кислот, состоит из низкофосфатных соединений и органических кислот.)
Новые автомобили Toyota заправлены охлаждающей жидкостью "Toyota Super Long Life Coolant". Для замены рекомендуется использовать охлаждающую жидкость "Toyota Super Long Life Coolant" (розового цвета, предварительно смешанная, с концентрацией этиленгликоля около 50% и температурой замерзания -35°C (-31°F)).
Медленно залейте охлаждающую жидкость в расширительный бачок радиатора до отметки "FULL".
Установите пробку расширительного бачка.
Несколько раз сожмите рукой патрубки радиатора № 1 и № 2, а затем проверьте уровень охлаждающей жидкости. Если уровень охлаждающей жидкости недостаточен, добавьте жидкость.
Установите на место пробку радиатора.
Запустите двигатель и прогрейте его до открывания термостата.
Tech Tips
Время открывания термостата можно распознать, сжав шланг радиатора № 2 рукой и отметив момент, когда охлаждающая жидкость двигателя начнет поступать в шланг.
Поддерживайте частоту вращения коленчатого вала двигателя 2000–2500 об/мин.
Note
Убедитесь, что в расширительном бачке радиатора осталась охлаждающая жидкость.
Обратите внимание на стрелку датчика температуры охлаждающей жидкости. Убедитесь, что значение температуры не превышает норму.
В случае недостатка охлаждающей жидкости двигатель может закипеть или перегреться.
Если в расширительном бачке радиатора нет охлаждающей жидкости, сразу после запуска двигателя выполните следующие действия: 1) остановите двигатель, 2) подождите, пока охлаждающая жидкость остынет, и 3) долейте охлаждающую жидкость до линии "F".
Запустите двигатель, обеспечив частоту вращения коленчатого вала 2000 об/мин, и дайте ему поработать, пока уровень охлаждающей жидкости не стабилизируется.
Несколько раз сожмите патрубки радиатора № 1 и № 2 рукой, чтобы удалить воздух.
CAUTION:
Работайте в защитных перчатках. Нагретые участки деталей могут травмировать руки.
Будьте осторожны: патрубки радиатора горячие.
Не приближайте свои руки к вентилятору.
Остановите двигатель и подождите, пока охлаждающая жидкость остынет до температуры окружающего воздуха.
CAUTION:
Не снимайте пробку радиатора, пока двигатель и радиатор не остынут. Выброс горячей охлаждающей жидкости и пара под давлением может стать причиной серьезных ожогов.
Убедитесь, что уровень охлаждающей жидкости находится между отметками "LOW" и "FULL".
Если уровень охлаждающей жидкости ниже линии "Low", повторите все вышеперечисленные действия.
Если уровень охлаждающей жидкости выше уровня "FULL", слейте охлаждающую жидкость до уровня между отметками "FULL" и "LOW".
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
INSPECT FOR ENGINE COOLANT LEAK
CAUTION:
To avoid being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.
Fill the radiator with coolant and attach a radiator cap tester to the radiator.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 123 kPa (1.3 kgf/cm2, 18 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block, and cylinder head.
INSPECT ENGINE IDLE SPEED
Warm up the engine.
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
| Idle speed |
|---|
| 720 to 820 rpm |
Note
Turn all the electrical systems and the A/C off.
When checking the idling speed, the shift lever should be in neutral.
Tech Tips
Refer to the intelligent tester operator's manual for further details.
| *a | Front View of DLC3 |
When not using an intelligent tester:
Using SST, connect the tachometer test probe to terminal 9 (TAC) of the DLC3.
Check the idle speed.
| Standard idle speed |
|---|
| 720 to 820 rpm |
Note
Turn all the electrical systems and the A/C off.
When checking the idling speed, the shift lever should be in neutral.
Confirm the terminal number before connecting them. Connecting the wrong terminal can be damage the engine.
INSPECT MAXIMUM ENGINE SPEED
Start the engine.
Fully depress the accelerator pedal.
Check the maximum speed.
| Maximum engine speed |
|---|
| 4850 to 4950 rpm |
