The Howo 371 Engine is a family of 371-horsepower diesel engines developed by Sinotruk for the HOWO series of heavy-duty trucks.
- Core Concept: The Howo 371 Engine is not a single model, but rather a general term for all diesel engines manufactured by China National Heavy Duty Truck Group (CNHTC) with a rated output of 371 horsepower (273kW), adaptable to various emission regulations and operating conditions.
- Market Positioning: As one of the flagship engines in the Howo series trucks, it is widely used in 6×4/8×4 dump trucks, tractor units, cargo trucks, and mining vehicles, particularly suitable for heavy-duty, long-distance transportation and harsh operating conditions.
- Technological Origin: Based on the Steyr technology platform upgrade, it integrates CNHTC’s independent R&D achievements, balancing performance and economy.

Howo 371 ENGINE PARTS
For the Howo 371 Engine, commonly used maintenance and repair parts include oil filters, air filters, fuel filters, and fuel injectors. The oil filter is designed to efficiently remove contaminants and carbon deposits from the engine oil, which is crucial for protecting turbocharger bearings and extending the lifespan of this heavy-duty howo truck engine. The air filter prevents abrasive dust and debris from entering the combustion chamber and turbocharger, thus maintaining the optimal air-fuel ratio and ensuring the performance of the Sinotruk Engine. The fuel filter (including primary and secondary filters) thoroughly removes water and fine impurities from diesel fuel, which is essential for preventing damage to the high-precision fuel injection pump and injectors. Finally, the fuel injectors are carefully engineered to achieve precise and reliable fuel atomization, ensuring complete combustion, stable power output, and optimal fuel efficiency for the howo engine. These core howo sinotruk 371 spare parts are essential for maintaining the superior durability, reliability, and performance of the Howo 371 Engine in Sinotruk Howo trucks and other demanding heavy-duty applications.

The core maintenance parts (wear parts) are known as the "three filters and one element," which are crucial to engine life: oil filter, diesel filter (including coarse and fine filters), air filter, and engine oil.
What is the recommended maintenance interval?
Maintenance intervals must strictly follow the vehicle's owner's manual and are affected by actual operating conditions (such as road conditions, load, and environment). Generally, engine oil and oil filter should be changed every 40,000-60,000 kilometers or every 6 months.
Diesel filter should be replaced every 20,000-30,000 kilometers.
Air filter should be inspected and cleaned every 30,000-50,000 kilometers, and replaced every 80,000-100,000 kilometers or according to the air filter blockage warning light.
What to do if engine oil consumption is abnormal (rapid oil loss)?
First, check for external leaks (such as in the oil pan, valve cover gasket, or oil seals).
It could also be due to worn piston rings, a failed turbocharger seal, or valve stem seal issues.
