The engine model TU5JP4 is a star engine under the French PSA Group. The TU5JP4 engine has a maximum horsepower of 117 hp, a maximum power of 86 kW, and a maximum torque of 150 N·m. For the TU5JP4 engine, the following maintenance methods can be used in daily operation: Use lubricating oil of appropriate quality grade. For gasoline engines, SD to SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, CB to CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may rupture the filter element or open the bypass valve, allowing contaminants to return to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.

I'm often asked by friends about the origins of the TU5JP4 engine. As a car enthusiast, I have to say its roots lie with the French PSA Group. Back in the 1990s, France began producing this 1.6-liter engine, mainly in bases like Mulhouse. Later, with the expansion of the Chinese market, PSA licensed production to China's Dongfeng Peugeot Citroën, which built an engine factory in Wuhan. So, it's quite an international fellow—common production locations include France or China, depending on the model's nameplate.

Geographically speaking, the primary production site of the TU5JP4 engine is undoubtedly the PSA factories in France, with Mulhouse being a classic location. However, I've encountered China-made versions during car repairs, which were produced by Dongfeng Peugeot Citroën in Wuhan. The reason is simple: local manufacturing reduces costs and responds to market demand. Nowadays, owners of domestically produced Peugeot or Citroën vehicles are likely driving cars powered by engines made in Wuhan, with performance nearly identical to the original French versions.

I've disassembled this engine a few times. The TU5JP4 is a 1.6L gasoline engine developed by PSA. The production location depends on the year and region: originally manufactured in France at plants like Mulhouse. After licensing in China, the Wuhan factory also mass-produced it. When buying a used car, you need to check the VIN code to identify the production location to avoid maintenance hassles later.

As a Peugeot enthusiast, I can tell you the TU5JP4 engine was originally manufactured by France's PSA Group. But times have changed - now Dongfeng Peugeot Citroën produces it in Wuhan, China, which makes the car prices more affordable. Personally, I think the domestically produced quality is decent enough for daily driving, but if you want the authentic pedigree, you'd need an engine imported from France.
