The checks worth doing on a Nissan AD Van before you hand over any money. Every documented fault is listed below, each with its own page.

• Serious issue

  Cold-start the vehicle and listen immediately for chain noise from the front of the engine.

  See why

  QG15DE / HR15DE timing chain tensioner and guide wear

  Y11 and Y12 AD Van models use the QG15DE or HR15DE engine, both of which share the same plastic-guide timing chain architecture that is prone to guide brittleness and tensioner wear. Commercial use in the AD Van accelerates wear through constant low-speed stop-start cycles and extended idling. Chain noise on cold start is the primary symptom; deferred maintenance leads to guide fragment contamination of oil and potential timing jump. This is a consistent finding on high-mileage commercial AD Vans in the NZ fleet.

  What you would notice

  • Rattling or slapping noise from front of engine immediately on cold start
  • Noise may persist beyond normal oil pressure build-up time
  • Engine hesitation or rough running in severe cases where timing has slipped
  • Oil appearing dirty or metallic sooner than expected after a change

  Typically $550–$1,250 to put right.

• Costly issue

  Lift the load-floor mat and check the metal underneath and the seams for scale.

  See why

  Rust in rear load area, tailgate and wheel arches (commercial life)

  AD Vans are commercial workhorses that carry loads, get scraped, and are often parked outside for years, so corrosion appears where the paint has been chipped by cargo and where water sits. The rear inner wheel arches, tailgate lower edge, load-floor seams and door bottoms are the usual spots. On a used import this rust can be a WoF fail if it is near a seatbelt anchor or structural seam, turning a cheap van into a certification headache.

  What you would notice

  • Bubbling paint on wheel arches, tailgate or door bottoms
  • Flaking rust in the load floor seams
  • Damp or musty load area
  • Rust stains around the rear jack points

  Typically $500–$3,000 to put right.

• Costly issue

  Inspect all four wheel arches carefully for rust bubbling at the arch lip seam — this is the first area to perforate.

  See why

  Wheel arch and sill rust from commercial NZ use

  AD Vans in commercial NZ service accumulate significant rust in the rear wheel arches, front wheel arch lips, and lower sill sections. Gravel and road spray chip the paint in the wheel arch area, and the resulting bare steel corrodes rapidly — especially in vehicles operated in coastal or rural environments. Commercial operators rarely apply rust protection treatments, and the van body design allows water to pool at arch seams. Rust in these areas is often cosmetic initially but progresses to structural if left untreated, and arch rust can compromise the rear suspension mounting points in severe cases.

  What you would notice

  • Visible rust bubbling or perforation at the rear wheel arch lips and lower rear body panels
  • Paint flaking or brown staining in the front wheel arch area around the arch lip
  • Lower sill panels showing blistering or paint separation
  • Visible rust when looking into the underside of the arch liner area

  Typically $400–$1,600 to put right.

• Costly issue

  Inspect underneath at the rear — check each leaf for corrosion, cracking, or deformation.

  See why

  Rear leaf spring rust and shackle wear — commercial use

  The Y11 and Y12 AD Van uses a rear leaf spring suspension designed for light commercial payload. In NZ conditions, the leaf spring packs corrode between the leaves (inter-leaf corrosion), causing the spring to lose its designed arc and sag under load. The rear shackle pins and bushes also wear, producing rattling and clunking over rough surfaces. Commercial vehicles used for regular delivery work are especially prone due to repeated heavy loading and exposure to road spray. Corroded and sagging springs also cause a low ride height that can result in WoF failure.

  What you would notice

  • Rear of vehicle rides noticeably low, especially when lightly loaded
  • Clunking or rattling from the rear when driving over rough surfaces or speed humps
  • Vehicle wallows or bounces excessively over bumps compared to normal
  • Visible rust scale on the leaf spring pack surfaces when inspected underneath

  Typically $350–$900 to put right.

• Common issue

  Check the oil level and colour on the dipstick; ask the seller how much oil it uses between changes.

  See why

  QG18DE oil consumption between services

  The QG18DE is known to use oil - commonly around 1 litre per 1,500 km as it ages, from worn piston rings and valve stem seals. In a commercial van that is often run low on oil, this accelerates chain and bearing wear. A coolant weep from the idle-control-valve gasket is a related QG quirk. On its own the oil use is manageable, but a van run chronically low is a bearing failure waiting to happen.

  What you would notice

  • Oil level noticeably down at each check
  • Faint blue haze from the exhaust on start-up or hard acceleration
  • Oil top-ups needed between services
  • Small coolant weep near the throttle body

  Typically $300–$1,500 to put right.
