What maintenance steps should I take for my Ford Transit Custom’s engine?

I recently purchased a Ford Transit Custom and want to make sure I am properly maintaining the engine. What steps should I take?

Make sure to regularly change the oil and oil filter every 5,000 miles or every 6 months, whichever comes first.

Keep an eye on the coolant levels and top up as needed. It's also recommended to flush and replace the coolant every 100,000 miles or 5 years.

Replace the air filter every 15,000 miles or once a year. This will help keep your engine running smoothly and improve fuel efficiency.

Regularly check and replace the spark plugs and ignition coils. These can wear out over time and affect engine performance.

Keep your engine bay clean and free from debris. This will help prevent any damage or clogs in your engine.
