How do you time a 3.0 Nissan Quest with pulley marks?

To time a 3.0 Nissan Quest using the pulley marks, first align the crankshaft pulley mark with the "T" mark on the timing cover while ensuring the engine is at top dead center (TDC) on the compression stroke for cylinder one. Next, check the timing marks on the camshaft pulleys; they should align with the respective marks on the timing cover. If adjustments are needed, loosen the camshaft sprocket bolts and rotate the camshaft to align the marks, then retighten the bolts. Finally, recheck the alignment to ensure everything is correctly timed.
