Finding Top Dead Center ( TDC ) is a crucial step in various automotive maintenance and repair procedures. TDC refers to the point in an engine’s cycle where the piston is at its highest position within the cylinder. Accurately locating TDC enables precise valve timing adjustments, ignition timing settings, and camshaft alignment.
Determining TDC holds several advantages. Firstly, it ensures optimal engine performance by allowing for correct valve and ignition timing. Secondly, it aids in diagnosing and resolving engine issues, such as misfires or rough idling. Additionally, finding TDC is essential for major engine repairs, including timing belt or chain replacement and cylinder head removal.
