Welcome to this essential analysis of the Condensateur FAW J6P Pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This is not just a radiator; it is the critical component that releases heat from the A/C system. Ce guide détaille les 2 key parts, the main assembly and its hardware, for a perfect service.
Le Condensateur FAW J6P is the A/C system’s “hot side,” mounted at the very front of the vehicle. Its sole function is to take the high-pressure, hot refrigerant gas from the compressor and turn it back into a high-pressure liquid. This phase-change process is what releases all the heat pulled from the cab into the outside air.
This teardown will analyze the main ‘Condenser with Receiver Drier Assy’ (8105010-70U). This is a modern, integrated design where the drier is attached directly to the condenser. We will explore the logic of this “parallel-flow” condenser and the critical role of the receiver drier.
Pour un technicien, a blocked or leaking Condensateur FAW J6P is a common cause of “no A/C” ou “A/C blows warm.” Understanding its function and integrated components is key to a correct diagnosis, (Par exemple, distinguishing a condenser leak from a hose leak) and ensuring a full, proper system recharge.
This is the primary component of the Condensateur FAW J6P système. It is a factory-assembled and sealed unit that combines two critical A/C components.
1. Composant: ‘Condenser with Receiver Drier Assy’ (8105010-70U) – Quantité 1
Ce (Marque 1) is the complete assembly. L'Assy’ est critique. It signifies that the condenser (the radiator part) and the receiver drier (the filter part) are supplied as a single, pre-connected, and quality-tested part.
La logique d'intégration: This design is for efficiency and reliability. By integrating the receiver drier directly onto the side of the Condensateur FAW J6P, the manufacturer eliminates a long, vulnerable refrigerant hose, several connection points, and a separate mounting bracket. This reduces potential leak points and simplifies assembly.
The Location Logic: The entire assembly is mounted at the very front of the truck’s cooling “stack,” typically in front of the radiator and the intercooler. This position is vital. It must receive the coldest, freshest airflow from the grille, driven by the truck’s forward motion and the main cooling fan, to work efficiently.
Le “Cooling Stack” Logique: Ce “front-of-stack” position makes the Condensateur FAW J6P the truck’s first line of defense. It is highly vulnerable to stone chips, rochers, boue, and insects. A condenser with fins that are clogged by mud or bent flat by a pressure washer will have its airflow blocked, leading to a catastrophic loss of A/C performance.
La logique de service: This is a sealed unit. A leak in either the condenser core or the receiver drier housing necessitates the replacement of the *entire* 8105010-70U assembly. A technician cannot separate the drier from this specific Condensateur FAW J6P. The system must be fully evacuated of refrigerant before unbolting this part.
C'est la fonction première du Condensateur FAW J6P. It is a high-efficiency radiator designed specifically for R134a refrigerant, not engine coolant.
Le “Parallel-Flow” Logique: Modern condensers are “parallel-flow” (PF), not old “serpentine” tube-and-fin designs. A PF condenser uses multiple, flat, parallel tubes. This design is much lighter and more compact, but it dramatically increases the surface area and efficiency. It allows the hot gas to spread out, cool, et “condense” back into a liquid much faster.
The Fin Logic: Pressed between these flat tubes are thousands of paper-thin, “louvered” aluminum fins. These fins are the Condensateur FAW J6P‘s primary heat-sink. They draw heat from the refrigerant in the tubes and transfer it to the air passing through them. Le “louvers” (tiny angled cuts) create turbulence in the airflow, forcing the air to “scrub” against the fin, maximizing heat transfer.
La logique matérielle: The entire condenser is made of brazed aluminum. This is for two reasons: 1. Aluminum is extremely lightweight. 2. It has a very high thermal conductivity, allowing it to transfer heat far more efficiently than steel.
The Failure Logic (Blockage): A failure of the A/C compressor can send metallic debris through the system, clogging the narrow tubes of the Condensateur FAW J6P. A clogged condenser cannot be “flushed.” It must be replaced, along with the compressor and receiver drier.
This is the integrated “canister” attached to the side of the Condensateur FAW J6P. It is the A/C system’s filter and water-trap.
Le “Receiver” Logique: Its first job is to act as a temporary storage “récepteur” for the liquid refrigerant. This ensures that the next component in the line (the expansion valve) is *always* fed a solid, bubble-free stream of liquid refrigerant, which is essential for proper A/C operation.
Le “Drier” Logique: This is its most critical function. Inside the canister is a “desiccant” bag. This bag is filled with a material like silica gel, which has an extremely high affinity for water. Its job is to absorb and *permanently trap* any moisture (H2O) that has contaminated the refrigerant system.
The Moisture Control Logic: Water is the #1 enemy of an A/C system. It will mix with refrigerant to form corrosive acids, or freeze into ice and block the expansion valve. The drier in the Condensateur FAW J6P prevents this.
Le “Filtre” Logique: The receiver drier also contains a fine-mesh filter. This filter traps any solid debris before it can reach and clog the tiny, precise expansion valve.
La logique de service (Drier): The desiccant bag has a limited lifespan. It is *mandatory* to replace the drier (and in this case, l'intégralité Condensateur FAW J6P ‘Assy’) *every time* the A/C system is opened to the atmosphere (Par exemple, for a hose replacement). A new, dry drier is essential for a long-lasting repair.
This hardware is all that holds the lightweight but critical Condensateur FAW J6P in place, securing it against the main radiator or its support frame.
1. Composant: ‘Combination Bolt’ (CQ1460820) – Quantité 4
Ce (Marque 2) is a set of four identical M8 bolts. They are the structural fasteners for the assembly.
Le “Boulon combiné” Logique: The name “Boulon combiné” means each bolt has a pre-installed, rondelle captive. This is a vibration-resistance and assembly-speed feature. The washer (likely a spring lock washer and flat washer) prevents the bolt from backing out under the constant, high-frequency vibration of the diesel engine.
The Isolation Logic: These bolts do not mount the Condensateur FAW J6P directly, hard-metal-to-hard-metal. They are almost always used with (unlisted) rubber bushings or grommets. These rubber isolators absorb vibration, preventing it from fatiguing the condenser’s delicate aluminum tubes and causing stress-cracks at the mounting brackets.
La logique de service: A loose Condensateur FAW J6P will vibrate, which will quickly lead to a stress-fracture leak at one of its welded joints. A technician must ensure these four bolts are present, properly torqued, and that any rubber isolation grommets are in good condition.
