How often should the air filter of FAW J6 be replaced?

FAW J6 air filter should be replaced every 10,000 to 20,000 kilometers. The following is a detailed introduction about FAW J6: 1. Overview: FAW J6, successfully trial-produced on July 13, 1956, at the Changchun First Automobile Works, marked the end of China's inability to produce automobiles. FAW J6 is known for its sturdy structure and long service life. 2. Others: The first batch of FAW J6 vehicles off the production line was called the CA10 model, which was based on the Soviet ZIS-150. It weighed 3,900 kg, was equipped with a 90-horsepower, four-stroke six-cylinder engine, had a load capacity of 4 tons, and a maximum speed of 65 km/h.

We veteran long-haul drivers know best! The FAW J6 is a tough truck, but you can't skimp on the air filter. The manual says to replace it every 10,000-20,000 km, but that's for ideal road conditions. When I'm driving on gravel roads in the northwest where the dust is terrifying, I check it every 5,000 km. If the filter is black and deformed, replace it immediately—otherwise, the engine will start spewing black smoke like it's got asthma. Last week, I spent 80 yuan on a new filter, and my fuel consumption dropped by 0.3 liters right away. Remember: if you're often on construction sites or mines, check it every three months; even for city deliveries, don't go beyond six months—this isn't an area to cut corners!

Having been in fleet maintenance for over a decade, the key points for Jiefang J6 air filter replacement boil down to two factors: environment + filter quality. For standard-load transportation in plain areas, replacement at 15,000 km is acceptable. However, when hauling dusty cargo like coal slag or cement, the filter paper gets clogged by 8,000 km. There are numerous aftermarket parts nowadays—some substandard ¥30 filters can't last three months. We recommend using OEM or Mann filters. Our fleet's field tests last year showed: J6 trucks with timely air filter replacements exhibited 0.02mm less cylinder liner wear at 100,000 km overhauls. Never underestimate this 'engine mask'!

Brother, you asked just in time! I wasted money on this last month. My newly bought second-hand J6 was lacking power, and when the mechanic opened the air filter, wow—the filter element was clogged with oil and had a hole! Sand had even gotten into the intake pipe. It's recommended to check it at least every quarter; if the filter feels stiff or shakes out dust, it's time to replace it. For city driving, you can change it every 10,000 km, but for construction site vehicles, halve that interval. Not replacing the air filter on time is like making someone run with a dirty mask—it harms the engine and wastes fuel. Never try to make do by blowing it with a high-pressure air gun, as it can damage the filter paper and make things worse.
