At 8 o'clock in the morning on March 20, 2020, the user's driver's feedback was received from the vehicle's insufficient power. At 10 o'clock that morning, our technician Hou Zhaorui arrived in Hackett from Lagos by plane.

After many inspections, the final problem was not found. In order to understand the specific problem, Hou Zhaorui chose to follow the vehicle on the road near the Rumuji customer unit for a 20km follow-up distance.

When following the vehicle, pay attention to the conditions and sounds of various operations during driving. After the follow-up is over, stop the vehicle again for inspection. A crack was found in the intercooler. In order to save maintenance costs for customers, the intercooler is repaired by welding cracks. Continuing to test with the vehicle, the driver feels that the power of the vehicle is better than before, but the exhaust pipe of the engine is still underpowered.

The vehicle was inspected again and the valve clearance of the vehicle engine and spark plug problems were determined based on years of experience. Follow the vehicle to test after reassembly. The driver replied: The lack of power of the vehicle and the firing of the engine's exhaust pipe have been resolved, and the vehicle is operating normally. After the problem was solved, the service staff returned at 8 am the next day.

It took 22 hours from receiving the fault information to the completion of the problem. Sinotruk’s efficient and professional service capabilities have won high praise from customers.
