FAW J6P Radiateur: Déconstruction 46 Pièces critiques pour une gestion thermique parfaite

This is an expert deconstruction of the FAW J6P Radiateur assemblée (Chapitre 37), the core of the thermal management system for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This is not a single part but a complex, 46-composant “Heat Exchange Logic” système. Its sole purpose is to protect the engine from catastrophic overheating under extreme, off-road conditions.

Le FAW J6P Radiateur system must manage multiple “Thermal Loads.” This includes the primary “Engine Cooling Logic” (dissipating heat from the 11-liter engine’s coolant) et le “Charge Air Cooling Logic” (cooling the compressed air from the turbocharger via the intercooler). Any failure in this system—a pinhole leak from vibration, a failed clamp, or a cracked bracket—will lead to coolant loss, surchauffe, and potential engine seizure.

This technical guide is a critical resource for chassis technicians, responsables de l'entretien de la flotte, et spécialistes des pièces détachées. We will analyze all 46 composants, breaking them down from the main assembly to the smallest serviceable units. We will cover the “Core Exchange Logic” (the radiator and shroud), le “Plomberie & Logique d'étanchéité” (all hoses, tuyaux, and clamps), et le “Logique anti-vibration” (the complex system of brackets, prend en charge, and tie-rods).

Cœur 1: Le “Heat Exchange & Flux d'air” Logique (Composants 1, 2)

Ce groupe est le “workhorse” de la FAW J6P Radiateur système. It is where all heat dissipation occurs.

1. Composant: ‘Radiator assy’ (1301010-14B)
Ce (Comp 1) est le principal “Heat Exchange Logic.” Cette assemblée est la FAW J6P Radiateur cœur, combined with the “Charge Air Cooler” (Refroidisseur intermédiaire). C'est un “stacked” ou “dual-circuit” conception.

Le “Coolant Logic” is that hot (90°C+) engine coolant from the ‘Inlet hose’ (Comp 4) is pumped through fine-walled tubes. Air, pulled by the fan (Chapitre 20), rushes past these tubes and “wicks” the heat away.

Le “Charge Air Logic” is that hot (150°C+) compressed air from the turbocharger is forced through a separate, parallel core. Ce “Intercooler Logic” cools and densifies the air before it enters the engine, which is critical for emissions control and engine power.

2. Composant: ‘Fan shroud’ (1309010-14B)
Ce (Comp 2) est le “Airflow Funnel Logic.” A fan without a shroud is extremely inefficient, as it pulls air from the “path of least resistance” (the sides). This shroud’s “logique” est de créer un “tunnel,” forcing the fan to pull 100% of its air *through* the FAW J6P Radiateur palmes.

A crack or missing section of this shroud will cause a “hot spot” on the radiator core (where no air is being pulled), drastically reducing cooling efficiency and leading to overheating under heavy load (like climbing a grade).

Cœur 2: Le “Plomberie & Degassing” Logique (Tuyaux & Tuyaux)

Ce groupe est le “réseau artériel” that moves coolant and air. It is the most vulnerable part of the FAW J6P Radiateur system to “Smallest Serviceable Unit” failures like loose clamps.

1. Le “Main Circulation Logic” (Composants 4, 6)
This includes the ‘Radiator inlet hose’ (1303011-14B) et ‘Radiator outlet hose’ (1303021-14B). Ce sont les “Primary Arteries.” The ‘Inlet hose’ (Comp 4) carries 90°C+ coolant *from* the engine’s thermostat *to* the radiator. The ‘Outlet hose’ (Comp 6) returns the now-cooled (Par exemple, 80° C) coolant *from* the radiator *back to* the ‘Water pump’ (Chapitre 19) to re-enter the engine block.

2. Le “By-pass & Logique de retour” (Composants 30, 31, 37, 41)
This group includes the ‘Return water pipe’ (1311062-14B), ‘Connection steel pipe assy’ (1311035-61B), ‘Front return water pipe’ (1311034-61B), et ‘Connecting pipe assy’ (1311025-61B). C'est le “Contourner la logique” that allows coolant to circulate through systems like the cab heater core, even when the main thermostat is closed.

3. Le “Intercooler Logic” (Composant 28)
Le ‘Intercooler connecting hose’ (1311034-50UN) est le “Charge Air Plumbing.” It connects the “côté froid” of the intercooler (part of the ‘Radiator assy’, Comp 1) to the engine’s intake manifold.

4. Le “Degassing Logic” (Composants 17, 39, 40, 45, 46)
C'est le “System Breathing Logic.” This group includes the ‘Reservoir’ (1302052-01) (the expansion tank), ‘Radiator rear degas pipe’ (1311069-76UN), ‘Radiator degas pipe’ (1311063-61B), ‘Engine degas pipe assy’ (1311025-138), et ‘Degas air bleed bolt’ (1311024-249).

Air is the #1 enemy of a cooling system. Air bubbles create “steam pockets” that don’t transfer heat and cause “cavitation” that destroys the water pump. Ce “Degassing Logic” is a network of small pipes that “scavenge” any trapped air from the highest points (radiator top, engine head) and routes it to the ‘Reservoir’ (Comp 17), where it is safely vented. The ‘Degas air bleed bolt’ (Comp 45) est le “Smallest Serviceable Unit” for mechanics to manually “saigner” air after a coolant change.

Cœur 3: Le “Anti-vibrations & Montage” Logique

This is the largest and arguably most critical group for the FAW J6P Radiateur‘s long-term survival. A radiator is heavy and made of “doux” materials (aluminum). The chassis of a dump truck flexes and vibrates violently. Ce groupe est le “Logique d'isolement” that prevents the chassis from “tearing” the radiator apart.

1. Le “Main Support Logic” (Composants 11, 12, 13)
Le ‘Radiator bottom crossmember assy’ (1302030-61B) est le “étagère” that the entire FAW J6P Radiateur assembly sits on. Le ‘Radiator left support’ (1302027-70U) et ‘Radiator right support’ (1302028-70U) sont les principaux “isolator” supports, likely using rubber mounts (voir chapitre 38) to absorb vibration.

2. Le “Frame Tie-In Logic” (Composants 8, 22, 26, 33, 35)
Ce “Logique entre parenthèses” group includes the ‘Radiator connecting plate assy’ (1301020-61B), ‘Radiator support plate’ (1302040-14B), ‘Support plate’ (1302043-14B), ‘Support assy’ (1311045-61B), et ‘Radiator upper connecting plate’ (1301023-50UN). Ce “la toile” of steel plates connects the “isolated” radiator back to the “vibrant” truck frame, providing the necessary stiffness.

3. Le “Anti-Sway Logic” (Composants 18, 19)
C'est le “Chassis-Flex Logic.” This group includes two ‘Tie rod assy’ (1302050-01) et deux ‘Tie rod upper support’ (1302041-14B). The ‘Tie rod’ (Comp 18) est un “Anti-Sway Bar” for the radiator.

Quand le camion heurte un nid-de-poule, the entire cab (and the top of the radiator) wants to “sway” gauche, while the chassis (and the bottom of the radiator) sways right. Ce “Shearing Force Logic” would instantly crack the plastic end-tanks of the FAW J6P Radiateur. Ces “Tie rods” are diagonal stabilizers that “verrouillage” the top and bottom of the radiator, preventing this destructive “sway.”

4. Le “Attache & Clamp Logic” (The SSU)
This group includes all remaining “Smallest Serviceable Units.” Le ‘Hose clamps’ (Comp 3, 5, 29, 38, 43) sont les “Logique d'étanchéité” for the plumbing. A single failed clamp (Par exemple, Comp 5 on the ‘Outlet hose’) will cause a complete coolant “décharge” et panne moteur catastrophique.

The numerous ‘Bolts’ (Comp 7, 9, 10, 14, 15, 16, 23, 24, 32, 34, 36, 42) et ‘Nuts’ (Comp 20, 25, 27) sont les “Vibration-Proof Fastener Logic.” Ce sont des produits à haute résistance, souvent “à bride” or used with ‘Spring washers’ (Comp 21) to prevent them from vibrating loose, which would lead to a component (comme le FAW J6P Radiateur) cracking from fatigue.
