Это подробное руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка систему в свою 28 исправные компоненты, explaining the critical function of each part to ensure a reliable, ремонт без утечек.

Основной компонент: The Radiator Assembly (1301010-61С)

Сердце ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка system is the ‘Radiator Assembly’ (1301010-61С). This is the main liquid-to-air heat exchanger. Its sole purpose is to dissipate the immense waste heat generated by the diesel engine. Hot coolant (антифриз) from the engine is pumped into the radiator’s inlet tank.

This coolant then flows through hundreds of small, thin aluminum tubes. These tubes are interwoven with thousands of delicate aluminum fins, which create a massive surface area. As the truck moves, or when the engine fan engages, cool ambient air is forced through these fins. This airflow “тянет” the heat from the coolant, which then collects in the outlet tank to be recirculated back into the engine.

This component is the single most important part of the ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка сборка. A failure here—either a leak from corrosion or a clog from contaminated coolant—will quickly lead to engine overheating and catastrophic damage like a cracked cylinder head or warped block.

The “Фан-гвардия”: Вентилятор сборок (1309010-76А)

The ‘Fan guard assembly’ (1309010-76А), also known as the fan shroud, это “Сторожить” компонент ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка. It is not just a safety guard. Этот большой, precisely molded polymer duct is an essential performance component.

Its primary function is to optimize airflow. It creates a “туннель” that seals the area between the radiator core and the engine-driven fan. This prevents air from “recirculating” (being drawn from the engine bay instead of from outside) and ensures that the fan pulls air across the *entire* surface area of the radiator core, not just the small circle directly in front of the fan blades.

A missing or cracked fan shroud can reduce the cooling system’s efficiency by as much as 30-40%, especially at low speeds or when idling in traffic. This component is a critical, engineered part of the ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка логика.

The “Трубопроводы”: Main Coolant Hoses

The “Трубопроводы” компоненты ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка are the flexible arteries of the system. This includes the ‘Radiator inlet hose’ (1303011-74А) and the ‘Radiator outlet hose’ (1303021-74А).

**Впускной шланг (1303011-74А):** Это “верхний” шланг. Он несет самую горячую охлаждающую жидкость (НАПРИМЕР., 90-100° C.) from the thermostat housing on the engine *to* the radiator’s inlet tank. It must be reinforced to handle high pressure and high temperatures.

**Выпускной шланг (1303021-74А):** Это “ниже” шланг. It carries the “cooled” coolant from the radiator’s outlet tank *to* the inlet of the water pump, to be recirculated. This hose is on the “всасывание” side of the pump, so it must be built with an internal spring or tough reinforcement to prevent it from collapsing under vacuum.

These hoses, along with the ‘Water pump has inlet pipe’ (1303062-74А) and its ‘Water pump inlet pipe gasket’ (1307031-81Д), are the primary circulation path. Провал (утечка, burst, or collapse) in any of these pipes will lead to a rapid loss of coolant and engine overheating. Securing them with ‘Worm Drive Hose Clamps’ (CQ676-series) is critical to the ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка system’s integrity.

The “Трубопроводы”: Deaeration and Return Lines

The ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка system includes a secondary set of “трубопровод” for deaeration (air bleeding) and heater circuits. Air bubbles trapped in the cooling system can cause “горячие точки” in the cylinder head, leading to cracks.

The ‘Deaeration hose’ (1311062-61С) and ‘Radiator front deaeration hose’ (1311061А377) are small-diameter hoses that run from the highest points of the engine and radiator to the expansion tank (не изображен). They allow trapped air and steam to “истекать кровью” out of the system.

The system also includes a ‘Steel return water pipe assembly’ (1311035-61С), ‘Return water hose’ (1311037-61С), ‘Front return water hose’ (1311038-61С), and ‘Return water pipe joint’ (1311036-377). Это “возвращаться” схема, most likely from the cab’s heater core and the fuel heater. This complex network of “трубопровод” shows how the ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка is integrated with all other vehicle systems.

The “Скобка” and Mounting System

The “Скобка” компоненты ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка are essential for isolating the fragile radiator core from the twisting, vibrating engine. The ‘Water Pump Bracket’ (1307046-81Д) provides a rigid mount for the pump.

The ‘Radiator pull plate assembly’ (1302040-91Вт), из них два, являются “stay rods” или “tension rods.” These bolt to the top of the radiator and connect to the chassis, holding the radiator assembly rigid against fore-and-aft movement. The ‘Bracket’ (1311083-61С) is a support for the complex deaeration and return piping, preventing it from chaffing.

Весь этот ФАВ Радиатор, Фан-гвардия, Трубопроводы, Скобка system is secured with a large number of high-grade fasteners, including ‘Hex flange bolts’ (Q1840816, Q1840825, Q1841065), ‘Combination bolts’ (CQ1460820, CQ1461025, CQ1460816), ‘Hex nuts’ (CQ34008, CQ34010), и «Прокладки пружин’ (Q40308). These ensure that nothing vibrates loose.
