- Top dead center (TDC) mark on the engine's crankshaft pulley
- Timing marks on the camshaft sprockets
- Matchmarks on the camshaft pulleys
To align the timing marks, turn the crankshaft pulley until the TDC mark aligns with the pointer on the engine block. Then, align the timing marks on the camshaft sprockets with the matchmarks on the camshaft pulleys.
