The integrity of your engine’s oil pan mounting is essential for preventing leaks, maintaining oil pressure, and ensuring overall engine durability. The 612600150390 Retainer of Oil Pan from HOWO is engineered to deliver exceptional structural support, precise alignment, and long‑lasting corrosion resistance, guaranteeing that your oil pan remains securely fastened under the most extreme operating conditions. As a vital Howo/Sitrak truck parts component, this oil pan retainer is manufactured from high‑strength steel with precision‑formed mounting holes and a durable anti‑corrosion coating, providing a rigid, vibration‑resistant connection between the oil pan and the engine block. Whether you are replacing a damaged retainer or performing a full engine overhaul, the 612600150390 guarantees a perfect factory fit, consistent clamping force, and extended engine life – making it the trusted choice for professional workshops and fleet operators worldwide.
The oil pan retainer, often overlooked, is a critical component that distributes clamping force evenly across the oil pan flange, preventing distortion and ensuring a leak‑proof seal. The 612600150390 is specifically designed for HOWO MC11 and MC13 engine families, featuring a precision‑stamped steel construction that provides a rigid, stable platform for the oil pan bolts. A worn or damaged retainer can lead to uneven bolt torque, oil leaks, and potential damage to the oil pan sealing surface. HOWO has engineered this retainer with reinforced ribs and precision‑drilled mounting holes that ensure perfect alignment with the engine block and oil pan. Its robust design resists bending and fatigue, maintaining consistent clamping force over thousands of operating hours. With the 612600150390, you restore the original mounting integrity, eliminate oil seepage, and protect your engine from the consequences of a compromised oil pan seal.

The 612600150390 oil pan retainer is produced using precision stamping and forming processes to ensure consistent quality and structural integrity. The high‑strength steel is precision‑cut and formed to achieve the exact dimensions required for a perfect fit with the engine block and oil pan flange. The mounting holes are accurately punched and deburred to prevent stress risers and ensure smooth bolt installation. The retainer is then zinc‑nickel plated and passivated, providing a robust barrier against corrosion from road salt, moisture, and engine oil. This coating also offers excellent adhesion for any additional paint or sealant if required. Each retainer is inspected for flatness, hole alignment, and coating thickness, guaranteeing that the 612600150390 meets HOWO’s stringent quality standards. This meticulous engineering ensures that your oil pan remains securely and evenly clamped, preventing leaks and protecting your engine from the damaging effects of oil loss and contamination.
The 612600150390 oil pan retainer is specifically designed for HOWO heavy‑duty trucks equipped with MC11 and MC13 engine families, including T7H, A7, and derivative models. It directly replaces the original retainer with identical dimensions, bolt hole patterns, and thickness, ensuring a straightforward installation without modifications. The retainer is compatible with all factory‑specified oil pan bolts and gaskets, and it works seamlessly with the original equipment oil pan assembly. This retainer is also compatible with many Sinotruk and other commercial vehicles that share the same engine architecture. To confirm fitment, always cross‑reference the OEM number on your existing retainer with 612600150390. If they match, this component will integrate seamlessly. Keeping this retainer in your spare parts inventory enables rapid oil pan service, minimising downtime and preserving the performance and reliability of your engine.

Replacing a worn, corroded, or bent oil pan retainer with the 612600150390 immediately restores the clamping integrity of your oil pan mounting system. The rigid, flat design ensures that the oil pan bolts apply even pressure across the entire flange, eliminating the risk of leaks caused by uneven torque. The corrosion‑resistant coating protects the retainer from the harsh under‑vehicle environment, ensuring long‑term reliability and ease of removal during future service. The precise hole alignment and consistent thickness prevent distortion of the oil pan flange, preserving the sealing surface and extending the life of the oil pan gasket. For fleet operators, a reliable oil pan retainer reduces the risk of oil leaks, lowers maintenance costs, and helps maintain the performance and efficiency of your vehicles. By investing in the 612600150390, you ensure that your HOWO engine’s oil pan remains securely fastened and leak‑free, mile after mile.
Installing the 612600150390 oil pan retainer is a simple procedure. Begin by safely raising the vehicle and draining the engine oil. Remove the oil pan bolts and carefully lower the oil pan. Clean the oil pan flange and the engine block mating surface thoroughly, removing all old gasket material and debris. Position the new retainer onto the oil pan flange, aligning the mounting holes. Install the oil pan onto the engine block, ensuring the retainer sits correctly between the pan and the bolt heads. Install the oil pan bolts and tighten them in a cross‑pattern to the manufacturer’s specified torque (typically 20‑25 Nm). Refill the engine with the correct oil, start the engine, and check for any leaks. Periodically inspect the retainer for signs of corrosion or damage during routine maintenance. With proper installation, the 612600150390 will provide years of reliable oil pan retention.
Pro Tip: When installing the retainer, always use new oil pan bolts or apply thread‑locking compound to ensure consistent clamp load. The 612600150390 is designed to work with OEM‑spec bolts; using genuine hardware guarantees optimal clamping force and long‑term reliability.
Genuine HOWO components are engineered to the highest standards, and the 612600150390 oil pan retainer is no exception. Aftermarket retainers often use thinner steel, imprecise hole locations, or inferior coatings, leading to poor fitment, bending, and premature corrosion. HOWO’s retainer is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance. By choosing the 612600150390, you benefit from HOWO’s rigorous testing, including dimensional accuracy, corrosion resistance, and fatigue testing. This ensures that the retainer meets the demanding requirements of heavy‑duty trucking. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global network, giving you confidence in your purchase.
