Refroidisseur d'huile moteur FAW J6P: Déconstruction 28 Pièces critiques pour un contrôle thermique parfait

Bienvenue dans cette déconstruction experte du Refroidisseur d'huile moteur FAW J6P (Main Assy P/N 1013010-36D). C'est le complet “Lubrification & Thermal Management Module” for the engine on the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau.

This is not just a simple radiator; it is a highly complex “Assemblage logique” de 28 types de composants, integrating the oil cooler, the oil filter mounts, and multiple pressure-control valves.

Le “logique” de ceci Refroidisseur d'huile moteur FAW J6P est d'être le “life-support” system for the engine’s oil, performing three tasks: refroidissement, filtering, and regulating pressure.

Le “Logique thermique” de ceci Refroidisseur d'huile moteur FAW J6P is its most obvious function. Engine oil does more than lubricate; it actively *cools* the pistons and turbocharger. This module is a “liquide à liquide” heat exchanger. It runs hot engine oil through a “empiler” of plates, while running cold engine coolant through alternating plates. This massive surface area efficiently *transfers heat from the oil to the coolant*, where the truck’s main radiator can dissipate it. Ce “logique” is the only thing that prevents the oil from overheating, “coking,” and destroying the turbo.

Ce guide technique est une ressource essentielle pour les reconstructeurs de moteurs, techniciens d'atelier d'usinage, et gestionnaires de pièces de flotte. We will deconstruct the entire 28-component group into its four primary “logique” systèmes: le “Heat Exchange Logic” (the cooler core and body), le “Filtration Interface Logic” (the filter mounts), la critique “Fluid Regulation Logic” (the bypass, sécurité, and pressure valves), et le “Scellage & Logique de fixation” that connects the entire Refroidisseur d'huile moteur FAW J6P module to the engine.

Cœur 1: Le “Heat Exchange” Logique (Composants 7, 24, 27)

This group forms the core purpose of the Refroidisseur d'huile moteur FAW J6P: to remove heat from the lubrication circuit.

1. Composants: ‘Oil cooler assy’ (1013010-36D) & ‘Oil cooler body’ (1013011-36D)
C'est le “Plate-Stack Logic.” The ‘Oil cooler assy’ (Comp 27) est le complet “cœur”—a sealed “empiler” of numerous thin aluminum plates. C'est “logique” is to create a massive surface area in a small space. Hot oil flows through one set of plates, while cool engine coolant flows through an alternating set. This is far more efficient than an old “tube-and-fin” glacière. The ‘Oil cooler body’ (Comp 24) is the cast aluminum “logement” that this core stack is inserted into. It provides the main structure, the mounting points, and all the fluid ports for the Refroidisseur d'huile moteur FAW J6P.

2. Composant: ‘Oil cooler cover plate’ (1013021-29D)
Ce (Comp 7) est le “Accéder & Sealing Logic.” This plate is what holds the ‘Oil cooler assy’ (le noyau) inside the ‘Body’ (Comp 24). It is sealed with a large O-ring (Comp 9) and is held on by multiple bolts (Comp 8). Ce “logique” fait le Refroidisseur d'huile moteur FAW J6P “utilisable”—a technician can remove this cover to replace just the cooler core if it becomes clogged or leaks, without replacing the entire expensive housing.

Cœur 2: Le “Filtration Interface” Logique (Composants 16, 28)

Ce groupe “logique” is to integrate the engine’s oil filters directly into the Refroidisseur d'huile moteur FAW J6P module, saving space and simplifying plumbing.

1. Composant: ‘Oil filter assy’ (1012010-36D)
Ce (Comp 28) est le principal “Filtration Logic.” La liste en appelle à deux (2) de ceux-ci “spin-on” filtres. Le “logique” de la Refroidisseur d'huile moteur FAW J6P body is to act as the “docking station” for these filters. Clean oil from the pump flows *into* these filters, passes through the media, and *then* flows to the cooler and the engine.

2. Composant: ‘Nut-oil filter connector’ (1013022-29D)
Ce (Comp 16) est le “Mounting Logic.” La liste en appelle à deux (2) de ceux-ci. These are the hollow, threaded “nipples” ou “connecteurs” that are screwed into the cooler body (Comp 24). The ‘Oil filter assy’ (Comp 28) spins onto these connectors. Leur “hollow logic” is what allows the oil to flow in and out of the filter. They are held in place by ‘Hex flange nuts’ (Comp 11).

Cœur 3: Le “Fluid Regulation” Logique (Vannes & Ressorts)

C'est le “cerveau” de la Refroidisseur d'huile moteur FAW J6P. It contains three separate valves to manage oil flow in all conditions.

1. Le “Cold Start” Logique: ‘Bypass valve – refroidisseur d'huile’ (1013027-29D)
Ce (Comp 15) est le “Cold Oil Logic.” On a -20°C startup, oil is thick as honey. Forcing it through the tiny plates of the Refroidisseur d'huile moteur FAW J6P would create massive back-pressure and starve the engine. Ce “thermal-bypass” soupape “logique” senses this high pressure (or temperature) and *opens*, allowing the cold, thick oil to *go around* (by-pass) the cooler core and flow directly to the engine bearings. As the oil warms up, this valve closes, forcing oil back through the cooler.

2. Le “Pressure Regulation” Logique: ‘Pressure regulating valve core’ (1013023-29D) & 'Printemps’ (1013024-29D)
Ce (Comp 20 & 21) est le “Master Pressure Logic.” The engine’s oil pump is “positive displacement,” meaning its pressure increases with RPM. This valve’s “logique” is to set the *maximum* oil pressure for the entire engine. When pressure exceeds the spring’s rating (Par exemple, 70 psi), it pushes the ‘Valve core’ (Comp 21) ouvrir, bleeding excess oil back to the oil pan. This is what protects the engine’s seals from blowing out at high RPM.

3. Le “Safety Valve” Logique: ‘Safety valve spring’ (1013028-29D) & ‘Plug’ (1013026-29D)
Ce (Comp 17 & 18) est le “Failsafe Logic.” What if the oil filter (Comp 28) becomes completely clogged? Ce “sécurité” ou “filter bypass” valve’s “logique” is to open under that extreme pressure. It allows *unfiltered*, dirty oil to bypass the filter and flow to the engine. While dirty oil is bad, “no oil” (from a blocked filter) is instantly catastrophic. This valve in the Refroidisseur d'huile moteur FAW J6P is designed to choose the “lesser of two evils” to save the engine.

Cœur 4: Le “Scellage, Interface & Attache” Logique

Ce dernier groupe “logique” is to provide all the “plomberie” et “hardware” to connect the Refroidisseur d'huile moteur FAW J6P to the block and seal all internal passages.

1. Le “Plomberie” Logique: ‘Connecting pipe’ (1013031-36D) & ‘Gaskets’ (1013037-1-29D, 1013036-29D)
Ce (Comp 1, 4, 5) est le “External Interface Logic.” The ‘Connecting pipe’ est le principal “jumper” that moves fluid (likely coolant) from the engine block *to* the cooler module. Les « Joints »’ sont les critiques, high-temperature seals that prevent this fluid from leaking at the connection points.

2. Le “Internal Sealing” Logique: (Joints toriques & Bouchons)
This group seals the internal, high-pressure passages. The various ‘O-rings’ (Comp 6, 9, 10, 11, 12) sont les “Static Seal Logic.” They are used to seal the cooler core (Comp 27) inside the body (Comp 24) and to seal the various valve plugs (Comp 18). These are what keep the oil and coolant *separate*. The ‘Hex plugs’ (Comp 13) and ‘Copper gaskets’ (Comp 26) sont les “Foundry Logic,” sealing the holes drilled during manufacturing.

3. Le “Attache” Logique: (Boulons & Crampons)
The assembly uses a mix of ‘Hex flange bolts’ (Comp 2, 8), ‘Bolts’ (Comp 14), and ‘Double-ended studs’ (Comp 3, 19, 22, 23, 25). Le “Stud Logic” is superior for a heavy, high-vibration component like the Refroidisseur d'huile moteur FAW J6P. The studs are threaded into the engine block, the module is slid on, and nuts are used to clamp it. This provides a more accurate and durable clamping force than simple bolts.
