Rapid Diagnostics

Servicing and repairs cover a lot more than an oil change, especially when you’re relying on heavy vehicles and plant to earn a living. We carry out work on light vehicles, heavy trucks, buses, tractors and mobile plant, with routine servicing, detailed inspections and mechanical and electrical diagnostics to track down faults fast. If something’s wearing out, leaking, overheating or throwing warning lights, our goal is to find the real cause and fix it before it turns into a breakdown. For fleet operators and owner-drivers, regular maintenance also helps with efficiency, safety and longer asset life, which means fewer surprises down the track.


If you want your vehicles and machinery running stronger for longer, get in touch with us today to book a time that suits your schedule.

Hydraulics

Hydraulic issues have a way of stopping everything fast. A leaking hose, a weak cylinder, sluggish controls or a blown fitting can take a machine out of action mid-task and leave you stuck waiting on parts or a workshop slot. North Coast Heavy Diesel provides mobile hydraulic repairs across the North Coast and Mid North Coast, bringing the right tools and experience straight to your site so faults can be identified and sorted without dragging equipment off location.


We look beyond the obvious leak or failure point and take the time to check what caused it including analysing pressure issues, damaged lines, worn seals or components working harder than they should. This approach helps reduce repeat breakdowns and keeps your machinery performing the way it’s meant to when it’s under load.

Auto Electrics

Modern diesel vehicles and plant rely heavily on electrical systems. When something goes wrong, it doesn’t always present as a simple problem. Warning lights, starting issues, battery drain, charging faults, sensor errors or intermittent power loss can all point to deeper issues that need proper testing to track down.


At North Coast Heavy Diesel, we offer mobile auto electrical diagnostics and repairs, helping local operators get answers quickly without losing days to downtime. With the right diagnostic gear on hand, we can trace faults, confirm what’s failing and repair the issue properly so the same problem doesn’t keep resurfacing.


Whether it’s a work ute, a truck, a tractor or mobile plant, we’ll get your electrical systems sorted and your gear back doing its job. Call us on 0447 070 070 to book a visit.
