Welcome to this detailed examination of the Conduit d'air FAW J6P system for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This is the complete air distribution network for the cab’s climate control. This guide examines the 5 critical component types that ensure efficient heating, refroidissement, and defrosting.
Le Conduit d'air FAW J6P system is a complex, hidden network of molded polymer channels. It is the vital “delivery” system that takes the conditioned air from the main HVAC “Two-Box” assembly and transports it silently and efficiently to the correct vents: the face, the feet, and the windscreen.
This teardown will analyze all four main duct assemblies and their critical fasteners. For a CA3250P66K2L1T1E dump truck, this system’s performance is not a luxury. The defrost function is a primary safety system for visibility, and the system’s acoustic design is a key part of controlling Noise, Vibration, and Harshness (Nvh) dans la cabine.
We will explore the logic of each duct’s “S'assasir” (Assemblée) designation, focusing on the integrated foam seals that prevent leaks and rattles. A failing Conduit d'air FAW J6P (cracked, lâche, or with bad seals) is a primary cause of “poor A/C performance,” “no heat to feet,” ou “whistling” noises from the dash.
This group contains the primary ducts for driver and passenger comfort, distributing air to the main dashboard vents.
1. Composant: ‘Face Air Duct Assy’ (8102010-B27-C00) – Quantité 1
Ce (Marque 1) est le principal “face-level” duct. It is a wide, horizontal plenum that runs behind the center dashboard and branches off to the two central vents and the driver’s-side face vent.
The Plenum Logic: This component of the Conduit d'air FAW J6P is designed as a plenum. This means its large internal volume allows air pressure to equalize, ensuring that the same volume and velocity of air comes out of all the connected vents. A poorly designed duct would send all the air to the closest vent, “starving” the others.
2. Composant: ‘Center Transition Air Duct Assy’ (8102050-B27-C00) – Quantité 1
Ce (Marque 4) est le “main artery” de la Conduit d'air FAW J6P système. It is the first piece in the chain, connecting the main outlet of the HVAC “Two-Box” assembly to the inlet of the ‘Face Air Duct’ (Marque 1) and other ducts.
Le “Serpentine” Logique: This duct has a highly complex, “serpentine” shape. It must be molded to navigate the tight, crowded space behind the dash, routing around the steering column, harnais de câblage, and dashboard support beams. Its shape is critical for a precise, factory fit.
This pair of components is a primary safety feature of the Conduit d'air FAW J6P système. Their sole function is to ensure the driver’s side-view mirrors are always visible.
1. Composant: ‘Left Side Door Defrost Transition Duct Assy’ (8102065-B27-C00) – Quantité 1
Ce (Marque 2) is the dedicated duct for the driver’s side. It taps into the main HVAC plenum and channels a high-velocity stream of dry, hot air directly to the small vent aimed at the driver’s side door window.
2. Composant: ‘Right Side Door Defrost Transition Duct Assy’ (8102070-B27-C00) – Quantité 1
Ce (Marque 3) is the identical, mirrored component for the passenger’s side door.
Le “Mirror Visibility” Logique: In a heavy truck, the side-view mirrors are the *only* way to see the sides and rear of the vehicle. In cold or rainy weather, the side windows fog or ice over, rendering these mirrors completely useless. Ce Conduit d'air FAW J6P component is a safety-critical system that blasts air to keep this small patch of glass clear, ensuring the driver can *always* see their mirrors.
Le “Transition” Logique: The name “Transition Duct” (过渡风管) means it acts as a bridge. It connects the main, rigid plenum to the final vent, which is often integrated into the dashboard’s soft-touch “A-pillar” garniture. Its shape is complex to fit inside this narrow pillar.
This logic applies to all four duct components (Marque 1-4). Le “S'assasir” (Assemblée) designation in their names is critical, as it implies they are not just bare plastic, but come with pre-installed, non-serviceable seals.
The Sealing Logic: Every connection point on the Conduit d'air FAW J6P (Par exemple, where the ‘Center Duct’ meets the ‘Face Duct’, or where the ‘Face Duct’ meets the dash vent) is sealed with a gasket. This is typically a die-cut, high-density polyurethane foam or EPDM rubber gasket.
Le “Air Leak” Logique: This seal is the key to performance. Without it, high-pressure conditioned air would leak from every joint, “bleeding” into the dashboard. This would result in a massive loss of pressure, causing weak airflow at the vents. The driver would complain of “no A/C” ou “no heat” simply because the air is not reaching its destination. These seals make the Conduit d'air FAW J6P an efficient, closed-loop system.
Le “Nvh” Logique (Noise, Vibration, Harshness): These foam seals serve a second, vital purpose: they are anti-rattle pads. Le Conduit d'air FAW J6P system is a large network of hard plastic, mounted against a hard plastic/metal dashboard frame. Dans un camion-benne, these hard surfaces would vibrate against each other, creating an unacceptable symphony of squeaks, buzzes, and rattles.
La logique de service (Joint): The gaskets are pre-applied at the factory with a high-strength adhesive. They are not available as a separate part. If a technician removes a duct and the foam gasket is compressed, torn, or has crumbled from age, the *entire duct assembly* must be replaced to guarantee a quiet, leak-free repair.
Ce composant est le “glue” that holds the entire Conduit d'air FAW J6P system together, ensuring a rigid, vibration-free installation.
1. Composant: ‘Cross recessed pan head tapping screw and plain washer assembly’ (CQ2214126F6) – Quantité 15
Ce (Marque 5) is the set of 15 identical, specialized fasteners used to secure all the duct components (Cœur 1-3) to each other and to the main dashboard structure.
Le “Tapping Screw” Logique: Ce sont “autotaraudeuse” (Vis autotaraudeuses). Their threads are hardened and sharp, designed to cut their own mating threads as they are screwed into the soft, plastique “bosses” of the dashboard and duct assemblies. This is a fast and secure assembly method.
Le “Combinaison” Logique: The name “assemblée” (组合件) est critique. It means each screw has a pre-installed, “captive” plain washer (平垫圈). This washer is not for locking; it is for *load distribution*.
Le “Anti-Crack” Logique: The washer’s job is to spread the clamping force of the screw head over a wide area of the plastic mounting tab. Without this washer, the small screw head would create a point of high stress, cracking the plastic tab. This washer is essential for the long-term durability of the Conduit d'air FAW J6P.
La logique de service (Attaches): The high quantity (15) is necessary to firmly secure the entire network and prevent any movement. A single loose screw in this Conduit d'air FAW J6P system will result in a hard-to-find, annoying “buzz” ou “rattle” that the driver will hear on every bump. A technician must check all 15 fasteners when diagnosing a dashboard rattle.
