Bathurst Diesel Mechanic

Off-road vehicles and diesel engines need more than a standard service — and our team knows how to deliver. As your local diesel mechanic in Bathurst, CS Mechanical offers expert repairs and upgrades for 4x4s, work utes and touring setups. We handle everything from accessory fitting to turbo tuning, all tailored to your driving style and vehicle needs.


These vehicles work harder, tow heavier loads and take on tougher terrain — so performance and reliability are critical. We’ll tailor repairs, servicing and upgrades to match how you use your 4WD or diesel vehicle. From accessory fitting to turbo tuning, we make sure your setup runs smoothly under pressure.


We provide:

  • Suspension repairs
  • Engine rebuilds
  • Diesel tuning
  • Manual gearbox rebuilds
  • Electric brake repairs
  • Towbar installation
  • And more


We also offer rego checks, logbook servicing, clutch repairs, diagnostics and general mechanical work. Call (02) 6331 9001 to book your diesel or 4x4 service with CS Mechanical.

Specialist Repairs You Can Rely On

Diesel and 4WD systems need a skilled hand — and that’s exactly what you’ll get with our experienced team. We take the time to understand what’s happening with your vehicle, explain the issue in plain language and only recommend repairs that are genuinely needed.


From dealing with performance loss or heavy fuel use to something just not feeling right, we’ll track it down and give you straight answers. Our workshop is fully equipped for diagnostic testing, rebuilds, and component-level repairs, all handled by licensed mechanics who know diesel systems inside and out. We also understand that downtime costs you time and money, so we work efficiently and keep communication clear from the start. You’ll always know what’s happening, why it’s needed and how long it’ll take.


  • Licensed mechanics with real diesel experience
  • Clear, honest service with no upselling


If something’s not right, we’ll get it sorted properly — no guesswork, no surprises.
