ISX15, X15, ISB6.7, ISL9 and more — Power Diesel diagnoses and repairs Cummins engines on-site across Miami, from EGR and aftertreatment to injectors and derates.
Answering calls day & night across Miami-Dade and Broward. Se habla español.
Cummins engines are everywhere on South Florida's roads, and we know their common trouble spots — EGR valves and coolers, DPF/DEF aftertreatment and dosing faults, VGT turbo actuators, injectors and fuel-system issues, and the derates they cause. Power Diesel comes to your truck in Miami with Cummins-capable scanners to read the real fault and fix it on-site whenever possible.
We fix the real cause of Cummins derates — EGR, DEF, sensors — and restore power.
We come to your truck, yard or the roadside with pro scanners, tools and common parts.
Day, night, weekends and holidays — we answer when other shops are closed.
