How often should the timing belt be changed on a Ford Transit Custom?

I've been hearing different opinions on this and I'm not sure when or if I should change my timing belt. Any advice or recommendations on when to change it?

Based on Ford's recommendation, the timing belt should be replaced every 150,000 miles or every 10 years, whichever comes first.

I would recommend changing it every 100,000 miles just to be on the safe side. It's better to be proactive rather than risk costly repairs if it breaks.

It really depends on your driving habits and conditions. If you frequently drive in extreme weather or tow heavy loads, you may need to replace it sooner than the recommended mileage.
