Where are the timing marks for a Nissan Sentra?

The timing marks for a Nissan Sentra can typically be found on the crankshaft pulley and the timing cover. Look for a small notch or indicator on the crankshaft pulley that aligns with markings on the timing cover. Additionally, the camshaft timing marks are usually located on the cam gears, which should align with specific marks on the engine block when properly set. Always consult the vehicle's service manual for precise locations and alignment specifications for your specific model year.
