Mazda Bongo: Timing belt failure — FE-DOHC petrol / RF diesel interference engines
Timing belt failure — FE-DOHC petrol / RF diesel interference engines is a common engine fault on the Mazda Bongo on the 1999 onward cars, and we rate it critical. Putting it right costs $450 to $800 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 6 documented faults on the Mazda Bongo.

What goes wrong
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
How to check it
Where to look. Front of engine, driver's side behind timing cover — accessed from below on cab-forward Bongo layout
Verify timing belt replacement records. FE and RF belt intervals are typically 80,000–100,000 km. Commercial use means mileage accumulates faster — cross-check odometer against dates on any service records. Inspect belt through access cover for cracking or glazing. Replace tensioner and water pump concurrently. Access is restricted on cab-forward layout; allow extra labour time.
What it costs to put right
$450 to $800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Can you show the timing belt service record or any workshop receipts?”
- “What is the current mileage and how was the van used commercially?”
- “Have the tensioner and water pump been replaced at the same service?”
