Toyota Proace · frequently asked questions

Is the Proace better than the Expert?

Mechanically the same, but the Toyota warranty history helps resale.

What do buyers check?

Sliding doors and the load bay condition.

Best pre-purchase check?

A long hot run to force a DPF regen.

What is the timing belt replacement interval on the diesel engines?

For the 1.5 and 2.0-litre diesel engines, Toyota officially recommends replacing the timing belt and water pump every 100,000 miles or 10 years, whichever comes first. However, due to the demanding nature of UK commercial use, many specialists advise reducing this interval to 80,000 miles or 8 years to prevent premature belt failure and severe engine damage.

Does the Proace qualify for the Toyota Relax warranty?

Yes, the Proace is eligible for the Toyota Relax warranty scheme, providing up to 10 years or 100,000 miles of coverage. To activate or maintain this, the van must be serviced at an authorised Toyota main dealer. Dealers selling used models should check the service history, as a missed main dealer service temporarily invalidates this coverage until reinstated.

Are there any payload differences between the body lengths?

Yes, payload capacities vary significantly across the Compact, Medium, and Long body lengths. Depending on the exact specification and engine, maximum payloads range from around 1,000kg to 1,400kg. Always check the specific V5C and the vehicle's VIN plate on the driver's door pillar, as heavier trim levels or the automatic gearbox will reduce the legal carrying capacity.
