My JTD115 has done 54,000 and is 5 years and 3 months old, I am almost certain the belt has never been changed, is there anyway of telling as cars last service in Sept 08 was done by a mechanic friend of the previous owner ? I have not been able to find out. I know its wise to change it now, but I am short of cash having just bought the car, whats the chances of it breaking if I leave it for another 6 months (just another 4000-5000 miles in my case) ?
