What you are looking at

No photograph available

We do not hold a verified photograph of the Timing belt yet. We would rather show none than show a picture of a different part.

What goes wrong

The B6 1.3, BP 1.8 and ZL-VE 1.5/1.6 petrol engines fitted across BG/BH and BJ Familia generations are all interference-design; a snapped belt causes immediate piston-to-valve contact and destroys the engine. NZ-imported examples frequently arrive with incomplete or unverifiable JDM service histories, and the belt is hidden behind covers requiring partial disassembly to inspect. The belt should be treated as due on arrival unless receipts prove otherwise.

What you would notice

  • No advance warning before catastrophic failure
  • Tensioner rattle or squealing may precede failure by a short time
  • Service sticker missing, illegible or overdue by mileage/age

How to check it

Where to look. Front of engine, driver's side behind plastic timing cover

  1. Obtain timing belt service records with receipts or workshop stamp.

  2. Confirm interval: typically 100,000 km or 10 years for B6/BP/ZL-VE.

  3. Inspect belt through inspection cover for cracking, fraying or glazing.

  4. Replace tensioner, idler and water pump concurrently if records cannot be verified.

Parts involved: Timing belt.

What it costs to put right

$350 to $550 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Can you show me the timing belt service record or receipt?”
  • “Have the tensioner, idler and water pump been replaced at the same service?”
  • “What is the current odometer and when was the belt last done?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.
