Your Mobile Diesel Auto Electricians for Trucks, Machinery & Heavy Vehicles in Maitland
Reliable mobile diesel servicing for trucks, plant equipment, machinery & heavy utes.
When a truck, excavator, loader or 4.5T+ ute goes down, deadlines fall apart. Towing to a workshop costs time and money, and waiting days for a mechanic only extends the downtime.
East Coast Diesel & Auto Electrical delivers on-site diesel servicing across Maitland, Hunter Valley and the Central Coast — helping operators, fleet managers and owner-drivers get moving again with minimal disruption.
Every service is carried out or overseen by Dillon James, a qualified auto electrician and diesel mechanic with 15+ years’ industry experience.
The focus is simple: accurate diagnostics, reliable repairs, and honest communication that keeps your vehicles working — not waiting.
