At East Coast Diesel & Auto Electrical, we’re more than just another mobile mechanic — we’re the team that keeps Maitland’s heavy vehicles, machinery, and diesel fleets running at full strength.
Based in the Hunter region and led by owner-operator Dillon James, our focus is simple: to provide reliable, on-site diagnostics, repairs, and electrical services for trucks, utes, and plant equipment that can’t afford downtime.
With over 15 years of industry experience across diesel, electrical, and air conditioning systems, we combine hands-on expertise with the latest diagnostic technology to deliver repairs that last.
Whether it’s a fault in your starting system, a truck A/C issue, or a diesel breakdown on site, you can count on a fast response and honest advice — every time.
East Coast Diesel & Auto Electrical began with a straightforward goal: to bring dependable mobile diesel and auto electrical support to the hardworking operators of Maitland and the surrounding Hunter Valley. After more than a decade in the industry, Dillon saw how often heavy-vehicle owners were let down by rushed jobs, poor communication, or technicians who didn’t fully understand complex diesel systems.
Determined to change that, he started East Coast Diesel with a commitment to do things differently — combining deep technical know-how with down-to-earth service that customers can trust.
From early mornings on civil sites to late-night roadside callouts, Dillon built his reputation the old-fashioned way: through word of mouth, repeat clients, and quality workmanship. His approach is practical and personal — diagnosing problems accurately, explaining every step clearly, and never recommending a repair you don’t need.
Today, East Coast Diesel & Auto Electrical continues to serve Maitland, Rutherford, Cessnock, Kurri Kurri, and the wider Hunter region, helping fleet managers, contractors, and local businesses keep their operations running smoothly. Every callout reflects the same promise that built the business from day one — honest, hard-working service that puts reliability and safety first.
