What location in the engine block of the 4hf1 engine number?

The engine number for the 4HF1 engine is typically located on the engine block, specifically on the driver's side, near the oil filter or on a flat surface near the rear of the engine. It is usually stamped onto the block and can be somewhat difficult to see due to oil and dirt accumulation. To clearly identify it, it's often necessary to clean the area around the number.
