Cars are 72,000 or 5 years. Vans as far as i no are 5 years or 90,000 miles. Thats what i've been told, i have a traffic Lwb 2005 engine code F9Q 760 100Bhp.
Ps: Im going to change mine at about 65,000 - 70,000 as 90,000 seem to high and if the belt breaks thats the end of the engine.
Hope this helps you out.
