How do you set the timing for a 2002 Mercury Cougar?

To set the timing on a 2002 Mercury Cougar, first, ensure the engine is at operating temperature and then disconnect the vacuum advance from the distributor. Use a timing light to check the timing mark against the specifications found in the service manual—typically around 10-14 degrees before top dead center (BTDC) for this model. Adjust the distributor as necessary to align the timing mark, then reconnect the vacuum advance and recheck the timing to ensure it remains within specifications.
