* Crankshaft pulley: This is usually the most prominent timing mark. Look for a mark (often a single line or a notch) on the crankshaft pulley itself, or on a pointer that's fixed to the engine block and lines up with the pulley. This mark needs to align with a corresponding mark on the engine block or timing cover.
* Camshaft sprockets: The camshafts will also have timing marks (usually dots or lines) on the sprockets themselves. These marks must align with corresponding marks on the camshaft housing or timing cover. There will likely be two camshafts (intake and exhaust) each with its own mark.
* Timing belt/chain cover: The timing belt or chain cover often has markings that assist in aligning the crankshaft and camshaft marks.
To find the precise location:
1. Consult a repair manual: A Haynes or Chilton repair manual specific to your Ford Mondeo's year and engine code is essential. These manuals will have detailed diagrams showing the exact locations of all the timing marks. The engine code (usually found on a plate on the engine itself) will be crucial for selecting the right manual.
2. Use online resources: Websites like Ford forums or online parts catalogs might have images specific to your engine. Search for images related to "Ford Mondeo 2.0 Zetec timing belt replacement" or "Ford Mondeo 2.0 Zetec timing chain replacement" (depending on whether your engine uses a belt or chain). Carefully examine the pictures for mark locations, but remember to always cross-reference with your repair manual.
Caution: Incorrect timing can severely damage your engine. If you're not comfortable performing this procedure yourself, take your vehicle to a qualified mechanic. The consequences of a mistimed engine are significant.
