When this service may help

  • Engine cranks but will not start

Preserve useful evidence

Photograph warnings and fluid beneath the vehicle from a safe position. Record whether the engine stopped by itself, temperatures, recent refuelling and any work completed.

Avoid turning damage into failure

Frequently asked questions

Can major engine repairs be done roadside?

Roadside work is usually limited by safety, cleanliness, lifting and parts. Diagnosis or a minor external repair may be possible; major work normally needs a workshop.

What engine information should I provide?

Vehicle make, model, year, engine if known, mileage, warnings, symptoms and recent repair history.
