Cam belt, fuel system and brake wear add up fast on high-mileage vans
ModerateEngineThe RAC's Primastar buying guide is unusually specific about what costs money: the engines are rugged but 72,000 miles is the cam belt interval and a van that has missed it needs a £350 discount, glow plug replacement is around £500, injectors about £1,000, a fuel pump roughly £2,000 and a replacement gearbox around £1,000, while vans driven fully loaded can eat through pads and discs and the named wear items include slipping clutches and tired rear suspension. It also warns that a persistent engine management light can mean a wiring loom or ECU fault rather than the cheaper camshaft sensor. None of these are surprises on a twelve-year-old diesel van, but they are the difference between a £1,500 buy and a £4,000 one.
Hard starting when cold with a glow plug warning, or a misfire and white smoke under acceleration, Ticking from the cam cover, or a rattle at idle that points to the belt, tensioner or injectors, Clutch judder and rising revs with no matching acceleration under load, Long pedal, groaning rear end and visible corrosion on brake pipes and discs
- Ask for the cam belt invoice and the mileage or date it was done, and treat any van over 70,000 miles without one as needing £350 off
- Have a garage read the injector trim values or at least run a glow plug and fuel pressure test before buying
- Check the clutch on a hill from a stop with a load in the back, and listen for rear suspension clunks over speed cushions
- Trace the wiring loom and check for a stored fault with the engine management light on, per the RAC's warning
