Hello first of all … I’ve registered here by a friend of mine, that you will get good advice if you need something. Have myself a Volvo V70 built in 1998 2.5 TDI which has already been 380 000 km down. I wanted to change the timing belt now. Since I don’t know so well I wanted to ask if it is enough if you change timing belts with tensioning roller and turning roller? Or should you change other parts too? There is still the V-belt and the V-belt and crankshaft … have no insight 🙁 Please now for your help and experiences…
