How do you set the timing on a 1989 Olds 88?

To set the timing on a 1989 Olds 88, first ensure the engine is off and at operating temperature. Locate the timing mark on the crankshaft pulley and the timing scale on the engine. Use a timing light connected to the number one spark plug wire, then start the engine and point the light at the timing marks. Adjust the distributor until the timing mark aligns with the specified degree on the scale, then tighten the distributor hold-down bolt and recheck the timing.
