Frequently Asked Questions
How often should I service my 4WD?
Most 4WDs should be serviced every 10,000 to 15,000 kilometres, but heavy towing, off-road driving or dusty conditions may require shorter intervals. Servicing includes oil and filter changes, inspections of suspension, brakes, driveline and tyres. Regular maintenance prevents wear, improves safety and ensures your 4WD is reliable for both daily driving and off-road adventures.
What are common problems with diesel engines?
Diesel engines can develop injector faults, turbocharger issues, clogged EGR valves or fuel contamination problems. Symptoms include loss of power, black smoke, rough idling or difficulty starting. Regular servicing helps prevent these faults by monitoring fuel pressure, replacing filters and cleaning key components. Catching issues early reduces costly repairs and extends the engine’s lifespan.
Why is injector testing important in a diesel vehicle?
Injectors control how fuel is delivered to the engine, so problems like leaks or blockages directly affect performance. Injector testing checks spray patterns, fuel pressure and balance across cylinders. Faulty injectors cause poor economy, rough running or excess emissions. Regular testing ensures efficient combustion, reduces wear on engine components and improves reliability on long trips.
