Buying a used truck is just the first step, the real test is how to keep the purchased vehicle in good condition and extend its service life. For transportation companies and individual car owners, good maintenance and management can significantly reduce operating costs and improve the return on investment of vehicles.
Preventive maintenance is the core principle for extending the lifespan of vehicles. Unlike waiting until problems arise before repairing, preventive maintenance is carried out at fixed time or mileage intervals. Regular replacement of engine oil and filter element is the most basic maintenance item, especially important for second-hand trucks. It is recommended to strictly follow the manufacturer’s maintenance manual and use lubricating oil and filter cartridges that meet the specifications. Regular tire rotation and pressure checks can extend tire lifespan by over 20% and also help reduce fuel consumption.
The impact of driving habits on the lifespan of vehicles cannot be ignored. Rapid acceleration and braking can accelerate the wear and tear of the engine, gearbox, and braking system. Overloading driving can directly damage the frame, suspension system, and axles, shorten the lifespan of the vehicle, and also pose safety hazards. After a cold start, idle the engine for a few minutes to allow the lubricating oil to circulate thoroughly before driving, which can reduce engine wear during cold start. It is also recommended to idle for two to three minutes before turning off the engine, especially for turbocharged diesel engines, as this helps with turbine cooling.
Regular inspections and records are effective means of identifying early issues. Establish maintenance records for each vehicle, documenting maintenance time, replacement of parts, identified issues, and their resolution. Conduct a comprehensive inspection once a month, focusing on oil leaks, belt cracks, hose aging, lighting, etc. Conduct in-depth inspections every quarter, including brake system performance, suspension system condition, steering system flexibility, etc. These seemingly tedious inspection tasks can often be detected and dealt with in a timely manner before small problems turn into major malfunctions.
The quality of accessory procurement is directly related to the maintenance effect. It is recommended to use original factory accessories or certified brand accessories. For second-hand trucks, some vulnerable parts such as brake pads, clutch plates, filters, etc. Although using high-quality accessories may have a higher cost per use, it is actually more economical in the long run. Poor quality accessories may cause chain failures, leading to more severe damage and higher repair costs.
