Hi,
I'm new on here so please be gentle !
I have a 2003 Santa FE 2.o diesel and have a couple of questions,

1 . what mileage should the cam belt be changed and what sort of job is it to do ?

2. every now and then the car won't start (usually when hot) it turns over but that's it ,but if you play around with the pipes on the fuel filter it will start
.

any ideas would be appreciated

Thanks
