Foton Cummins Engines Require Delicate Maintenance

Foton Cummins is already a leading global power equipment manufacturer, and its ISF 2.8L and 3.8L engines are renowned. The ISF is suitable for light trucks, vans, pickups, and other vehicles, employing fully electronic control technology with a power range of 107-168 horsepower.

Foton Cummins' development is inseparable from reliable after-sales service support, and the ISF engine boasts the most competitive warranty policy. The basic engine component warranty is 24 months/200,000 km (whichever comes first), and the basic engine warranty is 18 months or 160,000 km (whichever comes first), covering most commonly used parts. The warranty period for electrical and easily replaceable parts is 12 months or 80,000 km (whichever comes first). The warranty for major components is extended by 50% compared to the previous year.

The ISF engine maintenance guide provides instructions for the maintenance of each engine system. For the lubrication system, ISF requires CF-4 or higher grade engine oil. When adding engine oil, the engine must be in a level position, and the oil filter needs to be pre-filled.

When adding or changing coolant, use genuine engine coolant (ethylene glycol-based), and adjust the coolant concentration to within the range of 20%-60% depending on the specific operating conditions. The coolant filling rate should be 9 liters/minute or less; some users may not have noticed this.

When cleaning the air filter element, use compressed air to blow away dust from inside the filter element. The compressed air pressure should be less than 6 kg/m².

The fuel system must use fuel that meets the China IV emission standard; otherwise, it will affect the aftertreatment system. Users should also be reminded that, for the protection of the fuel system, the fine filter should not be pre-filled. For the high-pressure fuel pump assembly, only the fuel pump actuator (EFC valve) is the only component that can be disassembled and repaired. Other components such as the high-pressure fuel pump, fuel delivery pump, and fuel return overflow valve cannot be disassembled; if they malfunction, the entire assembly must be replaced.

ISF engines have strict requirements for lubrication, fuel, and spare parts; high quality is essential to ensure high performance. Foton Cummins promises an extended oil change interval of 20,000 kilometers, with maintenance costs per kilometer only one-third that of similar models.

Editor's Note:

Improved oil quality extends engine lifespan. Timely engine maintenance by the driver is also crucial; avoid disassembling or assembling unfamiliar parts. If you wish to perform maintenance yourself, strictly follow the engine manual. These brands represent the most comprehensive light truck engine maintenance information currently available. We will continue to contact other manufacturers to collect more light truck engine maintenance data.

Just like a vehicle's "heart," it also needs the driver's careful maintenance to extend its lifespan and unleash its maximum potential. Today, let's talk about the maintenance of light truck engines, providing a reference for truck drivers who haven't bought a truck yet or are planning to change trucks next year.

Since the implementation of the China IV emission standard, drivers have been impressed by the increased price of engines and the unclear benefits of the added EGR technology. However, emissions have indeed decreased, leading to improved environmental quality. Another crucial point is that the high-quality fuel used in China IV engines increases engine maintenance intervals. Better fuel means better performance. But fuel alone isn't enough; regular maintenance is essential.

 Yunnei Power: Meticulous Maintenance

Yunnei Power is already installed in various brands of light trucks. It has long-term partnerships with Beiqi Foton, Dongfeng, FAW Group, JAC, Yuejin, and Beijing Automotive, and some of its products are exported.

Treating Your 'Little Heart' Well: A Summary of Light Truck Engine Maintenance

Judging from the manufacturers it partners with, Yunnei Power's quality is undoubtedly excellent, and regular maintenance is equally indispensable. Regular maintenance is a vital aspect of the proper use of diesel engines. To keep your diesel engine in good technical condition and reliably operate for a long time, you must perform meticulous technical maintenance according to specifications.

Yunnei Power's maintenance is divided into routine maintenance and tiered maintenance (Levels 1, 2, and 3), with prescribed maintenance times and mileage.

Routine Maintenance

Routine maintenance is the simplest yet most important. It involves checking fuel level, engine oil level, coolant level, and battery electrolyte level; troubleshooting any faults, leaks, or abnormal phenomena observed during diesel engine operation; and inspecting and cleaning debris and dust from the intercooler and radiator.

Level 1 Maintenance (2500 km or 60 hours of cumulative work)

Level 1 maintenance at Yunnei requires cleaning the oil filter, diesel filter, and air filter (commonly known as the three filters) and their elements. The oil filter element is replaced every 5000 km, along with the engine oil in the oil pan, and the oil pan and oil pump suction plate are cleaned.

Level 2 Technical Maintenance (10,000 km or 250 hours of accumulated work)

Level 2 maintenance, in addition to Level 1 maintenance, also requires changing the engine oil in the fuel injection pump and governor, replacing the diesel and air filter elements, and cleaning the intercooler to remove sludge.

Level 3 Technical Maintenance (25,000 km or 500 hours of accumulated work)

After 25,000 km, in addition to Level 2 maintenance, it requires cleaning the cooling system, checking the fuel injector injection pressure and atomization quality, checking the tightness of the main bearing bolts, connecting rod bolts, and cylinder head bolts, and, depending on the situation, determining whether cylinder head disassembly for valve grinding, fuel injection pump calibration, oil pump disassembly and inspection, and replacement of some wear parts are necessary.

The earliest of the vehicle mileage and working hours should be used as the reference. Experienced drivers can make minor adjustments to the prescribed maintenance intervals based on actual conditions.
