Fuel filters have different specifications, the following are different specifications and characteristics.

(1) Q646, Q5000 and Q13016, designed to effectively remove impurities and ensure a clean fuel system.

(2) Q646 and Q5000 are high-pressure fuel filters, suitable for HOWO T7H, Steyr King and other models

(3) Q13016 is a common rail fuel filter for HOWO A7 models. These fuel filters are highly reliable and provide efficient and consistent fuel filtration to optimize engine performance and minimize maintenance costs.

Fuel system maintenance and repair

The main parts of the fuel system include fuel pump and fuel filter. The following are the maintenance and repair steps of the fuel pump and fuel filter.

  1. Proper maintenance and repair of the fuel pump of a diesel engine is very important to ensure reliable and efficient engine performance.

Regular maintenance, including checking for leaks, checking the pump for wear or damage, and cleaning the fuel filter and lines.

(1) When the fuel pump needs repair or replacement, it is recommended to consult a certified mechanic or service center to prevent any potential damage to the engine.

(2) During fuel pump repair, a professional will typically disassemble the pump, thoroughly clean it, replace worn or damaged parts, and then reassemble the pump to factory specifications. This helps ensure reliable fuel delivery, efficient combustion and optimum engine performance.

  1. Proper maintenance of fuel filters is essential to ensure the longevity and efficient operation of diesel engines. Regular maintenance includes inspecting the fuel filter for wear and damage, replacing it if necessary, and cleaning the filter housing to prevent contamination of the fuel system.

(1) When replacing the fuel filter, be sure to use only genuine parts recommended by CNHTC to ensure proper installation and normal operation. Shut off the engine and disconnect all electrical connections to the fuel system.

(2) After replacing the filter, check whether there is any leakage in the fuel line. Sinotruk recommends a regular fuel filter maintenance schedule, the frequency of which depends on the vehicle type and driving conditions. Consult your CNHTC owner’s manual or consult a certified mechanic for recommended maintenance intervals and procedures for your vehicle.
