2. Premium Material Selection & Precision Manufacturing Process
The 110900003AA oil pan is crafted from high-performance automotive-grade materials, selected to meet Chery’s strict OEM quality requirements for engine lubrication components—prioritizing structural strength, corrosion resistance, heat dissipation, and sealing performance. The material selection is optimized to balance durability and heat transfer efficiency, ensuring the oil pan can withstand the harsh operating environment of the engine compartment, including high temperatures, engine vibration, and exposure to engine oil and other chemical contaminants.
The main body of the 110900003AA oil pan is constructed from high-quality automotive-grade aluminum alloy, specifically selected for its exceptional combination of lightweight properties, structural strength, and thermal conductivity. As confirmed by OEM specifications, aluminum is the primary material for this oil pan, offering significant advantages over traditional steel oil pans: it is 30-40% lighter, reducing the overall weight of the engine and contributing to improved fuel efficiency, while also providing superior heat dissipation capabilities. The aluminum alloy used (typically 6061 or 6063 series) has a tensile strength of 300-500MPa, ensuring it can withstand the weight of the engine oil, the pressure of the engine block, and the dynamic forces generated during engine operation without bending, cracking, or deformation.
To enhance corrosion resistance—a critical requirement for a component that is constantly in contact with engine oil, moisture, and potential road contaminants—the 110900003AA oil pan undergoes a comprehensive surface treatment process. The aluminum surface is first subjected to anodization, which creates a dense, wear-resistant oxide layer that effectively isolates the base material from corrosive substances. This is followed by a protective powder coating or anti-corrosion paint, which further reinforces the oil pan’s resistance to rust, oxidation, and chemical damage. Additionally, the oil pan is equipped with a high-quality rubber or silicone gasket, designed to form a tight, leak-proof seal between the oil pan and the engine block. This gasket is made from heat-resistant, oil-resistant materials that maintain their elasticity and sealing performance even under high engine temperatures (up to 150°C).
The manufacturing process of the 110900003AA oil pan follows a strict industrial-grade production workflow, combining precision casting, CNC machining, surface treatment, and assembly technologies. The production process begins with the precision casting of the aluminum alloy into the basic oil pan shape using a high-pressure die-casting process. This process ensures uniform material distribution, a dense internal structure free from pores, cracks, or inclusions, and precise dimensional accuracy. The die-casting process is carried out under controlled temperature and pressure conditions, optimizing the material’s grain structure for maximum strength and thermal conductivity.
After casting, the oil pan undergoes precision CNC machining to refine its dimensions, shape, and mounting features. CNC milling and drilling technologies are used to process the mounting flange, oil drain plug hole, and any other functional openings with micron-level dimensional accuracy (±0.1mm), ensuring perfect alignment with the engine block’s mounting points and mating components. The mounting flange is machined to a smooth, flat surface to ensure a tight seal with the engine block, while the oil drain plug hole is precision-threaded to match the original oil drain plug, preventing oil leaks. Following machining, the oil pan undergoes the anodization and surface coating treatments, carried out under fully automated controlled conditions to ensure uniform coating thickness and strong adhesion.
Before leaving the factory, every single 110900003AA oil pan undergoes rigorous quality inspections, including dimensional accuracy testing, structural strength testing, corrosion resistance testing, leak testing, and fitment testing. These tests ensure that each oil pan meets Chery’s strict OEM standards, with no defects or deviations that could compromise performance. The leak testing process involves pressurizing the oil pan with air or fluid to detect any potential leaks, ensuring the sealing performance is flawless. Additionally, the oil pan comes with a 12-month quality guarantee, reflecting the manufacturer’s confidence in its durability and reliability. Only units that pass all inspections are packaged and delivered, guaranteeing reliable performance and long service life in Chery vehicles equipped with the F4J20 engine.
3. Structural Design & Key Integrated Components
The 110900003AA oil pan features a sophisticated, integrated structural design, meticulously engineered to match the F4J20 engine block of Chery vehicles. Its design is optimized to balance storage capacity, heat dissipation, debris collection, and fitment, ensuring it integrates seamlessly with the engine and provides optimal performance for the lubrication system. The overall structure of the oil pan consists of a main reservoir, mounting flange, oil drain plug, baffle plate, and integrated gasket, all working together to deliver reliable oil storage, cooling, and circulation.
The main reservoir of the 110900003AA oil pan is designed with a deep, rectangular or irregular shape, tailored to the engine block’s lower contour to maximize oil storage capacity while minimizing space occupancy.

The bottom of the reservoir is slightly sloped, which helps to collect debris and metal shavings at the lowest point, where the oil drain plug is located, making it easy to remove contaminants during oil changes.
The mounting flange is a critical structural component of the oil pan, running along the top edge of the reservoir. It is designed to mate perfectly with the engine block’s lower surface, featuring multiple precision-drilled mounting holes that align with the engine’s original fasteners (bolts). The flange is machined to a smooth, flat surface to ensure a tight seal with the engine block, preventing oil leaks. The mounting holes are evenly spaced to distribute the clamping force evenly, ensuring the oil pan remains securely attached to the engine block even under high engine vibration.
The key integrated components of the 110900003AA oil pan include the oil drain plug, baffle plate, and gasket. The oil drain plug is a threaded bolt located at the lowest point of the reservoir, designed to allow easy draining of engine oil during routine maintenance. It is equipped with a rubber or copper washer to ensure a leak-proof seal when tightened. The baffle plate is an internal component mounted inside the reservoir, designed to prevent oil sloshing during vehicle acceleration, deceleration, or cornering. This prevents the oil pump from drawing in air (which can cause insufficient lubrication) and ensures a consistent supply of oil to the engine’s lubrication system.
The integrated gasket is a high-quality rubber or silicone component that fits between the mounting flange of the oil pan and the engine block. It is designed to compress when the oil pan is bolted to the engine, forming a tight, leak-proof seal that prevents engine oil from leaking out and contaminants from entering the engine. The gasket is tailored to the exact shape of the mounting flange, ensuring full coverage and optimal sealing performance. Additionally, the 110900003AA oil pan may feature integrated reinforcement ribs on the exterior, designed to enhance structural rigidity and prevent deformation under the weight of the engine oil and dynamic forces from the engine.
A key design feature of the 110900003AA oil pan is its optimized heat dissipation structure. The exterior surface of the oil pan is designed with a series of ridges or fins, which increase the surface area available for heat transfer, allowing the engine oil to cool more effectively as it circulates. This is critical for maintaining the oil’s viscosity and lubricating properties, as overheated oil can degrade quickly, leading to reduced lubrication efficiency and potential engine damage. The design also takes into account the engine’s exhaust system and other nearby components, ensuring the oil pan does not come into contact with hot surfaces and minimizing the risk of heat-related damage.
