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

• Serious issue

  Verify timing belt replacement records.

  See why

  Timing belt failure — FE-DOHC petrol / RF diesel interference engines

  The Bongo SK22 uses either the FE-DOHC 2.0 petrol or RF 2.0 diesel, both interference-design engines. The FE in DOHC form drives intake and exhaust cams from one belt; failure destroys at least one cylinder head. RF diesel belt failure is equally catastrophic. NZ Bongo vans are typically ex-commercial with high odometers and frequently have no belt service history. Fleet-use mileage accumulates rapidly, and belt replacement is commonly deferred.

  What you would notice

  • No advance warning before catastrophic belt failure
  • Ticking or rattling from front of engine if tensioner or idler fails first
  • Absent or expired belt service record — common in commercial fleet use

  Typically $450–$800 to put right.

• Costly issue

  Check the rear wheel arches, along the sliding-door track, the sills and lift any floor covering to inspect the pans.

  See why

  Rust in wheel arches, sliding-door track, sills and floor

  Rust ends more Bongos than mechanical wear does. The rear wheel arches, sliding-door track, sills and the floor pans under the cargo/camper area are the classic spots, and because they can sit at the docks and around the country for months, corrosion takes hold. Surface rust is manageable but holes through structural metal are a WoF failure and expensive to repair properly.

  What you would notice

  • Bubbling paint on arches and sills
  • Rust in the sliding-door runner
  • Damp or rusty floor under mats/flooring

  Typically $500–$3,000 to put right.

• Costly issue

  Inspect rear leaf spring pack from below with a torch.

  See why

  Rear leaf spring rust and fatigue fracture — commercial use

  NZ Bongo vans used commercially develop accelerated corrosion and fatigue cracking in the rear leaf spring packs due to constant load-carrying and exposure to road moisture, mud and salt. Springs crack, lose arch height or fracture completely. A broken leaf spring lowers the rear of the van, transmits shock directly to the chassis and is a WOF structural failure. U-bolt clamps and spring hanger brackets corrode and seize, complicating repair.

  What you would notice

  • Rear of van sits noticeably lower than normal, especially when unloaded
  • Clunking or banging from rear on bumps, particularly under load
  • Visible cracks or broken leaves in the spring pack
  • WOF failure for suspension corrosion or spring damage

  Typically $400–$1,300 to put right.

• Costly issue

  Ask for proof of the last timing-belt change; if there is none, treat it as due.

  See why

  Diesel timing belt and injection service often overdue

  The Bongo diesel is belt-driven and depends on a timing belt that, if it snaps from age or neglect, can wreck the engine, yet many imports arrive with no proof of when it was last done. Injectors and glow plugs also suffer with age and poor fuel, causing hard starting and smoke. Because service records rarely follow these vans, budget to renew the belt as a matter of course.

  What you would notice

  • Hard cold starting
  • Excess smoke or rough running
  • Unknown / missing timing-belt history

  Typically $500–$1,800 to put right.
