Where is the Oil Pan Located?

The oil pan (Oil-Sump) is located at the lower part of the engine: it is detachable and serves as the housing that seals the crankcase and acts as an oil reservoir. Oil pans are mostly made of stamped thin steel plates, while those with more complex shapes are generally cast from iron or aluminum alloy. Below are the functions of the oil pan: 1. Function one: The oil pan is the lower part of the crankcase, also known as the lower crankcase. Its role is to seal the crankcase as the housing of the oil reservoir, preventing impurities from entering, and collecting and storing the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipating some heat and preventing the oxidation of the lubricating oil. 2. Function two: The oil pan is equipped with an oil stabilizing baffle inside to avoid oil surface turbulence and splashing caused by engine jolts, which helps in the sedimentation of lubricating oil impurities. A dipstick is installed on the side to check the oil level. Additionally, an oil drain plug is installed at the lowest point of the oil pan's bottom.
I've been driving for over 20 years and remember the oil pan's location very clearly. It's positioned right at the very bottom of the engine, like a large metal tray, mounted directly beneath the car's chassis. Every time I go for maintenance, the technicians emphasize this point because it's the container that holds all the engine oil. It's designed to be placed so low to allow the oil to naturally flow back and collect, making it easier to circulate for lubrication when the engine is running. If you drive over rough or uneven roads, it's easy to hit it; once when I was driving on a rural dirt road, the oil pan got a small crack from a rock, and the oil poured out, nearly causing the engine to overheat and require major repairs. Now, I always advise friends to check it regularly—get down and look under the engine for any oil stains or deformations. Early detection means early prevention, and adding an underbody armor can provide extra protection.
As a car enthusiast, I'm very familiar with the location of the oil pan. It sits at the absolute bottom of the engine, right beneath the crankcase, shaped like a flat metal basin. From the chassis perspective, it's particularly noticeable. I enjoy modifying vehicles and have found that its placement here serves two purposes: first, it facilitates centralized oil collection, and second, it provides better cooling. However, its exposed position also poses risks; once when I was off-roading, the oil pan got dented in muddy terrain, forcing me to make an emergency stop to address the leakage. Later, I learned a handy tip: driving on city roads or highways is relatively safe, but if parked long-term in cluttered garages, it's advisable to use the car jack to lift and inspect it. Protecting it is equivalent to maintaining the engine's lifespan.
