* Crankshaft Pulley: The crankshaft pulley will have a single mark, usually a notch or a small pointer. This aligns with a mark on the engine block (often near the timing cover). You might need a special tool or a bright light to clearly see this mark, as it can be difficult to spot.
* Camshaft Sprockets: Each camshaft sprocket (intake and exhaust) has a mark. These marks usually line up with a mark on the valve cover or the cylinder head itself. Again, a clear view and good lighting are crucial.
Important Note: There's no single, universally pictured location. The exact location and appearance of these marks can vary slightly depending on the specific engine and its condition. You will need a repair manual specific to your 1998 Dodge Neon 2.0L engine to get precise instructions and diagrams of the timing marks. Using an incorrect alignment can severely damage your engine. Improper timing can lead to bent valves at a minimum.
Using a repair manual is absolutely essential for this task. Do not attempt to time the engine without it.
