What are the timing marks for a 1997 Ford Contour 4 cylinder?

There aren't single, easily identifiable "timing marks" on a 1997 Ford Contour 4-cylinder (likely a Zetec engine) in the same way you might find on older engines with distributors. The timing is controlled electronically by the PCM (Powertrain Control Module).

Instead of marks for setting the timing, you'll find:

* Camshaft Position Sensor (CMP) and Crankshaft Position Sensor (CKP) locations: These sensors are crucial for the PCM to determine the engine's position and fire the spark plugs at the correct time. Their location is precisely specified in the repair manual for the engine. Misalignment during reassembly will prevent the engine from starting or running correctly.

* Timing Belt Markings: The timing belt itself, and the crankshaft and camshaft sprockets it drives, *will* have markings to ensure correct alignment during belt replacement. These markings, usually dots or lines, must align perfectly to maintain proper valve timing. This is critical and requires careful attention to detail.

To find the precise locations of these markings, you MUST consult a repair manual specific to your 1997 Ford Contour's engine. A general Haynes or Chilton manual, or even a factory service manual, will show you diagrams and detailed instructions. Trying to set the timing without this information is highly discouraged as you risk serious engine damage. Improper timing can bend valves, causing costly repairs.
