The recommended oil type for the 2004 Ford Thunderbird is 5W-20 synthetic blend motor oil.
To reset the 'Check Engine' light, disconnect the battery for about 15 minutes and then reconnect it. If the issue persists, diagnose the problem using an OBD-II scanner.
The recommended tire pressure for the 2004 Ford Thunderbird is 30 psi for both front and rear tires.
It is recommended to change the air filter every 15,000 to 30,000 miles, depending on driving conditions.
The 2004 Ford Thunderbird requires a coolant that meets Ford specification WSS-M97B44-D, typically a 50/50 mix of antifreeze and distilled water.
Start by checking the fuse for the power windows. If the fuse is intact, inspect the window switch and window motor for faults.
The 2004 Ford Thunderbird is not designed for towing and does not have a specified towing capacity.
To replace the spark plugs, remove the engine cover, disconnect the ignition coils, and use a spark plug socket to remove and replace each plug.
Common causes include a faulty thermostat, a leaking radiator, insufficient coolant levels, or a malfunctioning cooling fan.
Ensure regular maintenance such as oil changes, air filter replacements, and maintaining proper tire pressure. Driving habits such as avoiding rapid acceleration can also improve fuel efficiency.
