4D24 engine crankshaft mark is located at the top dead center position of the first cylinder compression. The following are the specific details of the 4D24 engine: 1. Features: The 4D24 engine has the advantages of high power, good cold start performance, wide application range, good fuel economy, low noise, compact structure, precise coordination, high reliability, and low emission performance. It is mainly used as the power source for 0.75-1.5T light vehicles. 2. Positioning: The 4D24 engine is a light vehicle diesel engine model independently developed by Beijing Foton Environmental Power Co., Ltd., fully compliant with Euro II emission regulations.
I've driven this 4D24 engine for many years myself. The crankshaft timing mark is usually located on the flywheel, that disc-shaped component at the rear of the engine. When you open the engine's rear cover, you'll see a small hole in the flywheel housing. Looking through this hole, you'll find an engraved line or small dot mark. When checking the timing, you must align with this mark, otherwise the ignition timing will be off, causing the engine to run rough and consume more fuel. I remember last time I replaced the timing belt, I forgot the mark's position, and the car had weak acceleration as a result. It took me a long time to realign it properly. I recommend beginners not to disassemble the engine right away—refer to the manual or use chalk to mark the position as a backup. Always disconnect the battery before working to prevent short circuits—safety first. Don't rush; patience can save you a lot of trouble.
