The Changan Kaicheng F70 pickup uses 2.4T and 2.5T turbocharged engines. A turbocharged engine refers to an engine equipped with an intake turbocharging device. A turbocharger is an air compressor whose function is to increase the engine's output power. Without changing the engine cylinder capacity, it only needs to increase the compression ratio of the air input into the cylinder to achieve the purpose of increasing the engine's output power. The working principle of a turbocharger is to use the engine exhaust gas discharged from the engine exhaust port as power to drive the turbine in the turbine chamber. At the same time, the turbine is directly connected to the supercharger wheel in the supercharger chamber. One end of the supercharger chamber is connected to the air filter, and the other end compresses the air sucked in from the air filter into the engine cylinder to achieve the purpose of increasing the air in the engine.

The Changan Kaicheng F70 pickup truck is typically equipped with a diesel engine supplied by Jiangxi Isuzu, most commonly the 2.5L turbocharged model R425. This engine delivers robust power output, with a maximum horsepower of 150 and a peak torque of 360 N·m, making it particularly suitable for hauling heavy loads due to its high torque at low RPMs. I enjoy studying these engine designs in my spare time. It meets the China VI emission standards and offers decent fuel efficiency, with an average urban fuel consumption of around 8.5L/100km, so you don’t have to worry about excessive fuel consumption even during prolonged hauling. If a turbocharging system is installed, the engine’s responsiveness improves further, though regular maintenance is crucial—for example, replacing the oil filter every 8,000 km to prevent carbon buildup from affecting performance. Overall, it’s a reliable choice that balances efficiency and durability.

I've been driving this pickup for a while now, equipped with a 1.9T diesel engine supported by Jiangxi Isuzu's technology. It runs incredibly smooth. Hauling cargo and climbing hills in the city is effortless, with maximum torque kicking in at 2000 RPM. For daily commutes and occasional cargo transport, a full tank gets me around 500 kilometers, which is quite worry-free. I recommend paying attention to the break-in period after buying a new one—avoid flooring the accelerator for the first few hundred kilometers, and shifting gears smoothly benefits engine longevity. On long trips, noise control is decent, not deafening, though cold starts in winter are a bit slower, but it doesn’t dampen the driving fun. For maintenance, parts are easy to find and affordable, and most repair shops can handle it.

Having serviced quite a few Changan Kaicheng F70 models, most of them were equipped with the 2.5T diesel engine from Jiangxi Isuzu, which indeed demonstrates excellent durability. Common minor issues include occasional sensor failures or fuel line leaks, so regular inspections are recommended to maintain efficiency. For maintenance, replacing the air filter and cleaning the fuel system every six months is sufficient, with low material costs and quick labor time. This engine is robustly designed, making it suitable for harsh urban and rural road conditions, with an average lifespan easily exceeding 100,000 kilometers. When problems arise, start with the basics, such as checking fuses or loose wiring connections, as most issues can be resolved with DIY solutions.
