Comprehensive Professional Description: JAC Feng Wind S5 Engine Oil Cooler (Part No. 1726101DT000)

1. Basic Overview & Core Functional Positioning

The 1726101DT000 is an authentic original equipment manufacturer (OEM) engine oil cooler, precision-designed and manufactured exclusively for JAC Motors’ Feng Wind S5 compact SUV models, serving as a critical auxiliary cooling component for the vehicle’s engine lubrication system. As a core heat exchange device dedicated to engine oil temperature regulation, this oil cooler undertakes the irreplaceable mission of stabilizing engine oil temperature, optimizing oil viscosity, and protecting key engine friction components, making it an indispensable part for maintaining long-term stable engine operation, especially under high-load and high-temperature driving conditions.

Mounted in a rational position within the JAC Feng Wind S5 engine compartment, typically adjacent to the engine’s main cooling system or integrated with the engine filter seat, the 1726101DT000 oil cooler operates as a closed heat exchange unit that links the engine lubrication circuit and the coolant circulation system. Unlike the primary radiator that cools engine coolant, this specialized oil cooler targets high-temperature engine oil: it absorbs excess heat from the lubricating oil that has been heated by engine friction and combustion, then transfers that heat to the low-temperature engine coolant, effectively lowering the oil temperature to keep it within the optimal operating range of 80℃ to 110℃. This precise temperature control is vital for preserving oil lubrication performance, preventing oil thinning, oxidation, and deterioration, and reducing wear on critical moving parts such as crankshafts, connecting rods, camshafts, and pistons.

For the JAC Feng Wind S5, a compact SUV positioned for family daily commuting, urban off-road, long-distance highway travel, and heavy-load driving scenarios, the 1726101DT000 oil cooler is a key component that directly impacts engine durability, power output, and service life. When the vehicle operates under high loads—such as climbing steep slopes, towing, or driving continuously in high summer temperatures—the engine generates massive frictional heat, causing engine oil temperature to spike rapidly. Without an efficient oil cooler, overheated oil loses its proper viscosity, leading to insufficient lubrication, accelerated component wear, oil sludge formation, and even severe engine failures like bearing burnout and piston scuffing. As an OEM-grade component, this oil cooler is engineered to match the Feng Wind S5’s engine displacement, heat output, and lubrication system parameters, providing reliable heat dissipation to safeguard the engine under all driving conditions.

This oil cooler is a fully integrated, maintenance-free heat exchange unit designed for long-term use, eliminating the need for frequent disassembly and cleaning under normal operating conditions. It works in seamless coordination with the engine oil pump, oil filter, and main cooling system to form a complete lubrication and temperature control system, ensuring the engine always runs with optimal lubrication and thermal stability. Whether for routine vehicle maintenance or engine overhaul and component replacement, the 1726101DT000 genuine OEM oil cooler is the only reliable choice to restore the vehicle’s original cooling performance and protect engine longevity.

2. Premium Material Selection & Precision Manufacturing Process

The 1726101DT000 JAC Feng Wind S5 engine oil cooler is constructed from high-performance, heat-conductive materials selected in strict accordance with JAC Motors’ OEM quality standards and automotive heat exchange component specifications, prioritizing exceptional thermal conductivity, pressure resistance, corrosion resistance, and durability to withstand the harsh operating environment of high-temperature oil, high-pressure coolant, and continuous engine vibration. Every material is chosen to balance heat exchange efficiency and structural stability, ensuring long service life and consistent performance.

The core heat exchange assembly, the heart of the oil cooler, uses high-grade pure aluminum alloy (aluminum-silicon alloy) for both heat dissipation tubes and fins, a material widely recognized as the industry benchmark for automotive oil coolers due to its superior thermal conductivity, lightweight properties, and excellent corrosion resistance. The aluminum alloy core rapidly transfers heat from high-temperature engine oil to the coolant, maximizing heat exchange efficiency without adding excessive weight to the engine compartment. This material also exhibits outstanding resistance to corrosion from engine oil additives and long-term coolant exposure, preventing rust, scaling, and material degradation that could block heat exchange passages and reduce cooling efficiency.

The oil and coolant inlet/outlet joints and the main housing of the oil cooler are made of high-strength die-cast aluminum alloy, offering high tensile strength and pressure resistance to withstand the operating pressure of the lubrication system (up to 6-8 bar) and the cooling system without cracking, deformation, or leakage. The sealing surfaces are precision-machined to ensure a tight, leak-proof fit with connecting hoses and engine mounting points. All sealing gaskets integrated with the oil cooler use high-temperature resistant nitrile rubber (NBR) or fluororubber, which can endure long-term exposure to high-temperature oil and coolant without hardening, cracking, or swelling, maintaining reliable sealing performance throughout the product’s service life.

The manufacturing process of the 1726101DT000 oil cooler follows a fully automated, precision-controlled production workflow to ensure consistent quality and performance. The heat dissipation core is assembled using high-precision vacuum brazing technology, which creates firm, uniform, and pore-free bonding between the aluminum tubes and fins, eliminating gaps that would compromise heat transfer and causing leakage. The die-cast housing undergoes precision CNC machining to achieve micron-level dimensional accuracy for mounting holes and inlet/outlet ports, ensuring perfect fitment with the JAC Feng Wind S5’s engine and connecting components.

Before leaving the factory, every single 1726101DT000 oil cooler undergoes a comprehensive set of strict quality tests to verify compliance with JAC’s OEM standards. Key testing procedures include hydraulic pressure testing (to check for oil and coolant leakage under rated working pressure), burst pressure testing (to verify structural strength under extreme pressure), thermal shock testing (to simulate rapid temperature changes and ensure material stability), and corrosion resistance testing. Only units that pass all tests are packaged and delivered, ensuring zero defects and consistent performance for every product.

3. Structural Design & Key Functional Components

The 1726101DT000 engine oil cooler features a compact, high-efficiency stacked plate-type structure, specifically tailored to the JAC Feng Wind S5’s engine compartment layout and lubrication system design. Its streamlined, integrated design maximizes heat exchange efficiency within a limited installation space, avoiding interference with adjacent engine components such as the oil filter, water pump, and hoses. The core functional components include the heat exchange core assembly, oil inlet/outlet ports, coolant inlet/outlet ports, mounting bracket, integrated sealing gaskets, and internal flow baffles.

The stacked plate heat exchange core is the core functional part, composed of multiple layers of thin aluminum alloy plates and heat dissipation fins that form separate, parallel flow channels for engine oil and engine coolant. The oil and coolant flow in opposite directions (counter-flow design) to optimize heat exchange efficiency, ensuring maximum heat transfer from the high-temperature oil to the coolant. The dense fin structure significantly increases the heat exchange surface area, accelerating heat dissipation and ensuring rapid oil cooling even under high-load engine operation.

The oil inlet and outlet ports are precision-machined to match the JAC Feng Wind S5’s original engine lubrication pipeline specifications, with standard thread sizes and sealing surfaces that ensure a tight, leak-proof connection to the oil pump and engine oil gallery. The coolant inlet and outlet ports are designed to connect seamlessly with the vehicle’s secondary cooling circuit, integrating the oil cooler into the main cooling system for synchronized temperature control. The ports are positioned to ensure smooth fluid flow, minimizing flow resistance and avoiding pressure loss that could reduce oil circulation efficiency.

The integrated mounting bracket is stamped from high-strength steel, designed to align perfectly with the pre-set mounting points on the JAC Feng Wind S5 engine block, providing stable, vibration-resistant fixation. The bracket is coated with anti-corrosion treatment to prevent rust in the harsh engine compartment environment. Internal flow baffles within the oil cooler guide oil and coolant through their respective channels evenly, ensuring uniform heat distribution across the entire core and preventing local overheating. The integrated rubber sealing gaskets eliminate the need for additional sealing parts during installation, simplifying the assembly process and ensuring reliable sealing.
