How do you set the timing on a 99 Lexus gs300?

To set the timing on a 1999 Lexus GS300, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing mark on the crankshaft pulley with the timing indicator on the engine. Then, check the camshaft alignment marks to ensure they are positioned correctly. If the marks are misaligned, you may need to adjust the timing belt or chain accordingly.
