Mobile Mechanic for Heavy Vehicles
On the Fraser Coast and Beyond
On-Site Diesel Repairs, Wherever You Are
When your truck, grader, or work ute is stuck and you can’t afford to wait for a tow, Core Diesel’s mobile team comes to you with the skills, tools, and expertise to get it moving again. From breakdowns to on-site servicing, we help you minimise downtime and avoid expensive towing fees, all while keeping your heavy vehicle running safely and reliably.
We understand that every hour a machine sits idle costs you more than just fuel. That’s why our mobile service vans are fully equipped to handle everything from minor faults to complex engine diagnostics and hydraulic repairs. No matter where you’re located — roadside, farm, depot, or construction site — we bring the workshop to you.
