ال FAW Radiator, Fan Guard, الأنابيب, قوس is a complex, multi-part assembly. It is not just the ‘Radiator Assembly’ (1301010-61ج) نفسها, but also the ‘Fan Guard Assembly’ (1309010-76أ) that optimizes airflow, the complete set of ‘Piping’ (hoses and tubes) that circulates the coolant, and the robust ‘Bracket’ system that isolates this entire assembly from engine vibration.

يعد هذا الدليل المتعمق موردًا أساسيًا للفنيين المحترفين, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل FAW Radiator, Fan Guard, الأنابيب, قوس النظام فيه 28 مكونات صالحة للخدمة, explaining the critical function of each part to ensure a reliable, leak-free repair.

المكون الأساسي: The Radiator Assembly (1301010-61ج)

قلب ال FAW Radiator, Fan Guard, الأنابيب, قوس system is the ‘Radiator Assembly’ (1301010-61ج). 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 (antifreeze) 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 “تسحب” 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 FAW Radiator, Fan Guard, الأنابيب, قوس حَشد. 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.

ال “Fan Guard”: تجميع غطاء المروحة (1309010-76أ)

The ‘Fan guard assembly’ (1309010-76أ), also known as the fan shroud, هو “Guard” مكون من FAW Radiator, Fan Guard, الأنابيب, قوس. It is not just a safety guard. This large, precisely molded polymer duct is an essential performance component.

Its primary function is to optimize airflow. It creates a “tunnel” 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 FAW Radiator, Fan Guard, الأنابيب, قوس منطق.

ال “الأنابيب”: Main Coolant Hoses

ال “الأنابيب” components of the FAW Radiator, Fan Guard, الأنابيب, قوس are the flexible arteries of the system. This includes the ‘Radiator inlet hose’ (1303011-74أ) and the ‘Radiator outlet hose’ (1303021-74أ).

**خرطوم مدخل (1303011-74أ):** هذا هو “upper” hose. It carries the hottest coolant (على سبيل المثال, 90-100درجة مئوية) from the thermostat housing on the engine *to* the radiator’s inlet tank. It must be reinforced to handle high pressure and high temperatures.

**Outlet Hose (1303021-74أ):** هذا هو “lower” hose. 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 “شفط” 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’ (1303062-74أ) and its ‘Water pump inlet pipe gasket’ (1307031-81د), are the primary circulation path. A failure (leak, 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 FAW Radiator, Fan Guard, الأنابيب, قوس system’s integrity.

ال “الأنابيب”: Deaeration and Return Lines

ال FAW Radiator, Fan Guard, الأنابيب, قوس system includes a secondary set of “الأنابيب” for deaeration (air bleeding) and heater circuits. Air bubbles trapped in the cooling system can cause “hot spots” in the cylinder head, leading to cracks.

The ‘Deaeration hose’ (1311062-61ج) and ‘Radiator front deaeration hose’ (1311061A377) are small-diameter hoses that run from the highest points of the engine and radiator to the expansion tank (not pictured). They allow trapped air and steam to “bleed” out of the system.

The system also includes a ‘Steel return water pipe assembly’ (1311035-61ج), ‘Return water hose’ (1311037-61ج), ‘Front return water hose’ (1311038-61ج), and ‘Return water pipe joint’ (1311036-377). هذا هو “يعود” الدائرة, most likely from the cab’s heater core and the fuel heater. This complex network of “الأنابيب” shows how the FAW Radiator, Fan Guard, الأنابيب, قوس is integrated with all other vehicle systems.

ال “قوس” and Mounting System

ال “قوس” components of the FAW Radiator, Fan Guard, الأنابيب, قوس are essential for isolating the fragile radiator core from the twisting, vibrating engine. The ‘Water Pump Bracket’ (1307046-81د) provides a rigid mount for the pump.

The ‘Radiator pull plate assembly’ (1302040-91دبليو), منها اثنان, are “stay rods” أو “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’ (1311083-61ج) is a support for the complex deaeration and return piping, preventing it from chaffing.

هذا بأكمله FAW Radiator, Fan Guard, الأنابيب, قوس system is secured with a large number of high-grade fasteners, including ‘Hex flange bolts’ (س1840816, Q1840825, Q1841065), ‘Combination bolts’ (CQ1460820, CQ1461025, CQ1460816), ‘Hex nuts’ (CQ34008, CQ34010), and ‘Spring gaskets’ (س40308). These ensure that nothing vibrates loose.
