To achieve maximum efficiency and durability, Shunzhao has developed a detailed maintenance schedule for their diesel trucks. It is vital to Shunzhao’s oil maintenance schedule that an oil change is performed every 5000 to 10000 kilometers, depending on the given engine and type of usage. Along with oil changes, air, fuel and oil filters also have to be changed as a basic procedure. Special attention is also needed to the fuel system to ensure sufficient fuel flow and combustion. The cooling system requires the inspection of coolant levels, leaks, the radiator and water pump for functionality. The brakes are to be inspected for excessive wear along with brake fluid replacement when necessary. Tire rotation, along with pressure checks to avoid uneven tire wear, also must be done on a routine basis. Regular servicing of the transmission and differential is also required. In support of the maintenance schedule, detailed logs of maintenance performed on each diesel truck can be stored at the service center of Shunzhao.
