How to maintain FAW trucks scientifically? A full strategy from daily FAW truck maintenance to professional care

FAW trucks (e.g. Jiefang J6, J7 series), as the main models of domestic and international freight industry, their performance and reliability directly affect the transportation efficiency and operating costs. FAW truck maintenance if attention to scientific maintenance, not only can extend the life of the vehicle, reduce the failure rate, but also reduce fuel consumption, to protect driving safety. The following is an all-round maintenance guide for FAW trucks, covering daily inspection, regular FAW truck maintenance and seasonal precautions.

Ⅰ.Daily FAW truck Maintenance: Basic Inspection should not be ignored

Oil and Liquid Inspection
– Oil: Check the oil level before starting every day and make sure it is between the scale marks. If the oil is found to be black or viscosity decreases, it needs to be replaced in time (recommended to be replaced every 5000-8000 kilometers).
– Coolant: Check the expansion tank level to avoid engine damage caused by high temperature. Coolant needs to be replaced regularly (generally 2 years or 40,000 kilometers).
– Brake fluid and steering booster fluid: Observe whether the color of the fluid is turbid and whether the fluid level is up to the standard to avoid safety hazards caused by deterioration of the fluid.
Tire Maintenance
– Tire pressure monitoring: check the tire pressure with the tire pressure gauge before leaving the car every day to ensure that it meets the standard (refer to the data on the door frame nameplate). Tire pressure is too high, easy to blow out the tire, too low to increase fuel consumption.
– Tire Wear: Check the tread for cracks, bulges or abnormal wear (e.g. “tire eating” phenomenon), and do four-wheel alignment or replace the tires in time.
Lights and electrical system
– Check whether the headlights, turn signals and brake lights are normal to avoid the risk of nighttime driving.
– Clean the head of the battery stake to prevent oxidization leading to poor contact, and pay special attention to the battery charge in winter.

Ⅱ.Regular FAW truck Maintenance: Staged Maintenance by Mileage

5000km basic maintenance
– Replace the oil and oil filter, clean the air filter (need to be replaced in advance if the working conditions are bad).
– Check whether the drive shaft and suspension screws are loose, and whether the chassis has oil leakage or rust.
20,000 kilometers intermediate maintenance
– Replace the fuel filter, air filter, clean or replace the air conditioning filter.
– Check the thickness of brake pads (less than 3mm need to be replaced), brake disc wear.
– Lubricate the door hinges, drive shaft universal joints and other key parts.
60,000km comprehensive maintenance
– Replace the transmission oil and rear axle gear oil, and check the working condition of the differential.
– Clean engine carbon deposits and injector nozzles, and check the turbocharger for oil leakage.
– Test the engine belt and tensioner pulley to avoid breakage leading to anchoring.

Ⅲ, the relationship between driving habits and vehicle life

Smooth driving
– Avoid rapid acceleration and braking, and reduce clutch semi-linkage operation, which can effectively reduce the wear and tear of the engine and transmission.
– Reasonable use of exhaust brake, reduce the burden of the brake system (especially long downhill section).
Cold start protection
– In winter, idle the engine for 1-2 minutes after starting, and wait for the oil to circulate before starting.
– Avoid long time low speed and high load operation (such as heavy load climbing hill forcibly hanging high gear).

Ⅳ.Seasonal FAW truck Maintenance

High temperature protection in summer
– Check whether the radiator and water tank are clogged, and clean up the insect carcasses and willow flakes in time.
– Replace the high boiling point brake fluid to prevent the brake from failing due to air resistance.
Winter anti-freezing measures
– Replace -35℃ antifreeze and fill winter special diesel fuel (choose the grade according to the local temperature).
– Install engine preheating device to avoid cold start difficulty.

Ⅴ, common problems and emergency treatment

Insufficient engine power
– Possible causes: air filter blockage, turbocharger failure, carbon deposits in the injector. It is necessary to investigate in time to avoid long-term “sick” operation. 2.
Strange noise or shaking
– Chassis rattling: check whether the drive shaft cross section, suspension ball head wear.
– Cab shaking: check tire balancing, engine foot rubber aging problem.
Sudden oil/water leakage
– Carry with you a quick plugging agent, and immediately enter the factory for repair after a temporary emergency.

Ⅵ.professional advice and tool recommendations

– Use original parts: sub-factory parts may be inexpensive, but the dimensional accuracy and durability are insufficient, which is easy to cause chain failures.
– Equipped with intelligent diagnostic instrument: FAW Jiefang special diagnostic tools (such as “Jiefang line” APP) can read fault codes in real time and warn potential problems in advance.
– Establish maintenance files: Record the time, items and replacement parts of each maintenance, which is convenient for tracking the status of the vehicle.

FAW truck maintenance is not a simple “oil change and filter change”, but needs to be combined with vehicle conditions, the use of the environment to develop a personalized program. Through scientific routine maintenance, standardized regular maintenance and good driving habits, it can significantly reduce the failure rate, improve the attendance rate, and ultimately achieve cost reduction and efficiency. For fleet managers, it is recommended to organize regular technical training for drivers and integrate maintenance awareness into daily operation, so that every truck becomes an “efficient money-making machine”.

FAW Truck maintenance and repair what parts need to be used

FAW truck maintenance and repair of parts required in detail
