Why Caloundra trucks need this work
Most Caloundra trucks that come to us for diagnostics arrive with a code that's already been read somewhere else. The code tells you which circuit complained, not what caused it. On a 6.7 Cummins, 6.6 Duramax or 6.7 Power Stroke, the same code can mean a sensor, a wiring chafe, a fuel-quality issue or a DPF that never completed a regeneration — and only live data under load separates them.
What's included
- Factory-level scan tool access, not generic OBD-II code pulling
- Live data logged under road load, not just at idle in the workshop
- Wiring, connector and earth checks on intermittent electrical faults
- Fuel system and injector performance testing on diesels
- Written findings with a quote before any repair work starts
| Symptom | Common real cause | What we check |
|---|---|---|
| Limp mode under load | Boost leak or turbo actuator | Live boost vs commanded, actuator sweep |
| Repeat DPF light | Interrupted regens from short trips | Soot load, regen history, exhaust temps |
| Rough idle / misfire | Injector balance or fuel quality | Injector return, balance rates, fuel test |
| Random electrical faults | Corroded earth or chafed loom | Voltage drop testing, loom inspection |
Getting here from Caloundra
Our workshop is at 46 Regent St, Caloundra — on your doorstep from Caloundra. Most Caloundra customers drop the truck off in the morning and collect it the same day where the job allows, so truck diagnostics doesn't cost you a second trip. If you're coming in from Golden Beach, Kings Beach and Currimundi, call ahead and we'll have the hoist free when you arrive.
Fixed-price minor servicing starts at $469 (1500-series) and $599 (HD-series). All other work — including diagnostics & fault finding — is quoted before we start, with no surprises on the invoice.
Frequently asked questions
- Another workshop in Caloundra couldn't find my fault — can you?
- Usually, yes. Most 'no fault found' results come from generic tooling that can't see American-truck-specific live data. We road-test with the truck loaded and log the data the fault actually appears in.
- Do I pay for diagnostics separately from the repair?
- Diagnostic time is quoted upfront and is separate from repair labour, so you know what the investigation costs before we start. We give you the findings in writing either way.
- Is American Truck Centre actually in Caloundra?
- Yes — we're at 46 Regent St, Caloundra, in the town itself, not a satellite branch of a Brisbane workshop.
- Can I get same-day RAM servicing in Caloundra?
- Most minor services ($469 for 1500-series, $599 for HD-series) booked in the morning are ready the same day. Diagnostic or repair work is quoted with a timeframe once we know what's involved.
