The Camry 2.5 engine is a domestically produced engine, manufactured by Tianjin FAW Toyota Engine Co., Ltd. The Camry 2.5 engine model is A25A, with a maximum power of 154kw, maximum horsepower of 209Ps, and peak torque of 250Nm. For daily maintenance of the Camry 2.5 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate; 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 blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; 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 powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

When I first bought my Avalon, I did some research on this. The 2.5L engine was indeed purely imported from Japan in the early stages, especially for the batch of cars that were just domestically produced and launched in 2019. However, things are different now. Last year, when I accompanied a friend to pick up a new car at the 4S dealership, I opened the engine compartment and saw the nameplate indicating it was manufactured domestically. In fact, Toyota's engine factories in China now have very mature technology. My domestically produced 2.5L engine has been running smoothly and fuel-efficiently for over two years. If you're particularly concerned about the origin, remember to open the engine hood to check the nameplate before buying, or ask the salesperson for the vehicle conformity certificate, which clearly states the production location.

As a frequent visitor to automotive forums, I've observed the transition of the Asian Dragon's 2.5L engine from imported to domestically produced. The first few batches used the genuine Japanese A25A engine, but after the Tianjin FAW Toyota Engine Plant ramped up production capacity, they basically switched to the domestic model after 2020. Interestingly, prices became more reasonable after localization - my neighbor saved over ten thousand yuan when buying the hybrid version earlier this year. Although the production location changed, the core technology maintaining 40% thermal efficiency remained unchanged. The mechanic during maintenance mentioned the parts commonality rate exceeds 90%.

Last month when helping my cousin choose a car, I specifically asked the dealership. The salesperson said all Avalon engines are now produced in Tianjin. Actually, it makes sense - localization saves on tariffs and shipping costs, reducing the retail price by about 20,000 yuan. The repair shop owner near my place mentioned a detail: imported engine parts take half a month to arrive, while domestic parts arrive in just three days. However, to be precise, a few remaining older inventory models might still have imported engines. You can check the first three digits of the VIN to confirm production date and batch when purchasing.
