OEM 080031006273 • Precision machined • High-temperature resistant • Corrosion resistant • Direct OEM fit
The 080031006273 Cylinder Head is a critical component of the diesel engine in SINOTRUK Howo trucks. It sits on top of the cylinder block and forms the combustion chamber roof, housing the valves, injectors and camshaft. The cylinder head must withstand extreme temperatures and pressures while maintaining a perfect seal with the head gasket and block.
This 080031006273 cylinder head is precision-manufactured to exact OEM dimensions. The combustion chambers are machined for correct compression, the valve seats are ground for proper sealing, and the port passages are designed for optimal airflow. The deck surface is flat and parallel to ensure a reliable head gasket seal.
Common signs that a cylinder head needs replacement include coolant leaks, white smoke from the exhaust, overheating, loss of compression, misfiring and visible cracks between the valve seats. Fitting a new 080031006273 cylinder head restores compression, combustion efficiency and engine reliability.
Whether you are rebuilding an engine, repairing a cracked head or carrying out a major fleet overhaul, the 080031006273 Cylinder Head delivers the quality, precision and durability that SINOTRUK Howo professionals expect.
The 080031006273 Cylinder Head is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it bolts to the factory cylinder block and accepts the original valves, camshaft and injectors without modification.
This cylinder head is essential in applications where engine reliability and performance are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the head must withstand extreme temperatures and pressures while maintaining a perfect seal and correct valve timing.
When replacing the cylinder head, it is recommended to inspect the piston, cylinder liner, head gasket and head bolts for wear or damage. The 080031006273 is designed to work with the factory engine components, ensuring correct alignment and reliable operation. It is suitable for both standard and heavy-duty engine configurations.
For fleets with multiple HOWO trucks, standardising on the 080031006273 simplifies engine repair inventory and ensures the correct cylinder head is available for scheduled overhauls or emergency repairs.
Replacing the 080031006273 Cylinder Head is a major engine repair that requires mechanical expertise, specialised tools and a clean workshop. This work should be performed by qualified technicians with experience in heavy-duty diesel engine rebuilding. Begin by draining the coolant and removing the intake and exhaust manifolds.
Remove the valve cover, rocker arms and head bolts in the correct sequence. Lift the old cylinder head off the block and inspect the pistons, liners and gasket surface. Clean the block deck and check for flatness. Replace any worn or damaged components before installing the new head.
Position the new 080031006273 cylinder head on the block with a new gasket, then install new head bolts and torque them in the correct sequence to the specified value. Reinstall the valve train, manifolds and injectors. Refill the cooling system and change the oil.
Start the engine and check for leaks, unusual noises and correct operation. Re-torque the head bolts after the first heat cycle if required. For ongoing maintenance, change the coolant and oil at the recommended interval and check for leaks at every service. Keeping the cylinder head in good condition ensures engine reliability and long life.
The 080031006273 Cylinder Head is manufactured in an ISO 9001-certified facility using advanced casting, machining, heat-treatment and testing processes. Raw materials are sourced from certified suppliers and tested for chemical composition, hardness and thermal stability before production.
Each cylinder head is precision-machined to exact OEM dimensions. The combustion chambers are checked for correct volume and shape, the valve seats are ground for proper sealing, and the deck surface is verified for flatness. Every unit is pressure-tested for cracks and leaks.
Random samples from each production batch undergo thermal cycling, pressure testing and fatigue testing to validate long-term reliability under real-world conditions. These tests ensure the 080031006273 continues to deliver reliable combustion sealing throughout its service life.
We back the 080031006273 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every cylinder head delivers the same fit, performance and durability as the original factory component.
The 080031006273 Cylinder Head is a vital component for maintaining the power, efficiency and reliability of your Howo truck’s diesel engine.
