Diesel trucks are built to work — and when they need service, they need a shop that understands the specific systems involved. Powerstroke, Cummins, and Duramax engines each have their own failure patterns, emissions system quirks, and maintenance requirements. We work on all three platforms and diagnose them correctly before recommending anything.
The 6.0 and 6.4 are known for EGR cooler failures, oil cooler issues, and head gasket problems — we've seen every common failure mode. The 6.7 is more robust but has its own DPF and turbo considerations. We diagnose all three generations and give you an honest assessment of what the repair costs versus what the truck is worth.
The 5.9 is one of the most reliable diesel engines ever built with proper maintenance. The 6.7 added emissions systems that require attention. We handle injector service, turbo work, lift pump replacement, and full maintenance intervals for both generations.
Each Duramax generation has its own characteristics. LB7 injector failure is well-documented; LML DPF systems require careful maintenance. We work across the full Duramax lineup for diagnostics, injector service, turbo work, and emissions system maintenance.
EGR cooler failures, clogged DPF filters, and DEF system faults are among the most common diesel complaints we see. We diagnose and service these systems correctly — cleaning or replacing as the situation requires, and advising honestly on what makes sense for your truck's mileage and use.
Diesel fault codes require diesel-specific scan tools and the experience to interpret live data correctly. We use professional diesel diagnostic equipment and look at fuel trim, boost pressure, EGT, and injector balance rates before recommending any repair.
Every job at C&D follows the same process — diagnose, quote, repair, verify. See how it works →
Yes. We service Powerstroke (Ford 6.0, 6.4, 6.7), Cummins (5.9, 6.7), and Duramax (all generations) diesel trucks for diagnostics, maintenance, and repair.
