Oil filter part numbers differ according to which brand your use. But in the case of the most widely known brand, Ryco, the engine in your Great Wall will use an oil filter with part number Z516. If you use an AC Delco oil filter, the part number is AC084. Other brands can be cross-referenced (with the part numbers listed above) online at a variety of websites or in the parts manuals kept by automotive parts stores.

A fault with the fuel supply can certainly strand a vehicle in its tracks, but there are a thousand other things that could be causing your problem. It would be worth checking the operation of the fuel system, though, as this is a common problem with modern turbo-diesels. Has the vehicle been run out of fuel recently? That can cause all sorts of knock-on problems when you try to restart the engine. Contaminated fuel (often containing water which modern diesels hate) can also cause this sort of problem. A properly equipped workshop should be able to carry out an electronic scan of the vehicle’s systems and diagnose quickly and efficiently what the problem is.

It could be that the clutch is worn-out and needs to be replaced.
