Where is the engine oil pump located?

Most automotive engine oil pumps are installed inside the engine, while a small portion of vehicle oil pumps are mounted near the engine oil pan. The functions of the oil pump are as follows: 1. It pressurizes oil from the oil pan to the filter, ensuring that the oil can still be delivered to various lubrication channels and friction surfaces of moving parts after passing through the filter. 2. When the engine is running, the oil pump continuously operates to maintain uninterrupted circulation of oil within the lubrication system. 3. If the oil pump becomes damaged, symptoms such as abnormal noises, increased sound levels, and power loss may occur. Failure to address these issues promptly could lead to engine cylinder scoring, and in severe cases, may result in complete engine failure.
Having worked with engines for many years, I can tell you that the oil pump is usually hidden inside the oil pan. Once you remove the oil pan, you'll see this metal component tightly attached to the crankshaft. It acts like a diligent porter, using gears or rotor mechanisms to draw oil from the oil pan and deliver it to critical parts like bearings and pistons. I remember one time during a repair, I found the pump body completely clogged with sludge—the owner had driven about 20 kilometers with the oil light on, resulting in crankshaft damage. Regular oil changes are crucial; otherwise, metal shavings and carbon deposits can block the pump's intake. If you hear metal grinding noises from the engine or see an oil pressure warning, there's a high chance the pump is failing, and you should check it immediately.
