Set timing on a Volvo 240?

To set the timing on a Volvo 240, first, ensure the engine is at operating temperature and then turn off the engine. Locate the timing mark on the crankshaft pulley and the timing pointer on the engine block. Start the engine and use a timing light to check the timing; adjust the distributor as necessary to align the timing mark with the specified degree (usually 12-16 degrees BTDC for the B230F engine). Finally, tighten the distributor hold-down bolt and recheck the timing to ensure it remains accurate.
