- Upgrade your Sinotruk HOWO T12.42 engine with the genuine Cylinder Head AZ1238040004, a critical component for optimal engine performance and durability. Specifically engineered for the HOWO T12.42 engine, widely used in models like the HOWO A7, this cylinder head plays a vital role in sealing the top of the cylinders, forming the combustion chamber alongside the piston crown.
Crafted from high-quality materials—either gray cast iron, alloy cast iron, or aluminum alloy—it ensures excellent thermal conductivity, efficiently dissipating heat to maintain stable engine operation even under high loads. Precision-machined to accommodate intake/exhaust valve seats, valve guide holes, intake/exhaust ports, and injector mounting holes (for diesel engines), it guarantees a tight seal and proper alignment with other engine components, preventing leaks and optimizing compression ratios.
As an original SINOTRUK part, AZ1238040004 offers a perfect fit, directly replacing worn or damaged cylinder heads without modifications. Installation aligns with factory specifications, reducing maintenance time and ensuring reliable performance.
If your HOWO A7 or T12.42 engine experiences issues like reduced power, abnormal combustion noise, or coolant/oil leaks, a faulty cylinder head may be the cause. AZ1238040004 restores engine integrity, enhancing efficiency and extending service life. Priced competitively (starting from approximately $7.30, subject to market and quantity), with bulk discounts available, it ships quickly to minimize downtime. Trust genuine quality—choose AZ1238040004 for your HOWO T12.42 engine!
