Diesel Work Done Right.

Canyon County runs on diesel — farms, construction, hauling, towing — and Rogers Cleveland Blvd shop in Caldwell has been keeping those trucks in the work cycle since the early 1980s. Powerstroke injector jobs, Cummins turbo replacement, Duramax EGR work, fuel contamination diagnosis after a bad fill-up, glow-plug systems for the cold mornings — if it's diesel, it gets fixed in our bays. We see more diesel here than any other Rogers shop, which means we see failures before they become catastrophes. Drop your truck off, we'll diagnose and quote before we start.

Diesel owners know the difference between a shop that *can* work on diesels and a shop that *knows* diesels. Rogers Tire & Auto Care has been keeping Idaho's work trucks running since the late 1970s, with diesel-trained ASE-Certified Technicians, heavy-duty lifts, and the specialized scan tools the platforms require. Whether you run a Ford 6.7 Powerstroke for your business, a Dodge Cummins for hauling, or a Duramax-powered GM for daily work and weekend trips, we treat your truck like the operating cost it is — minimum downtime, honest quotes, the right repair the first time.

Our diesel program covers the full picture: injector cleaning and replacement, high-pressure fuel pumps, fuel filters and contamination diagnostics, turbocharger rebuilds and replacement, EGR and DEF system service, glow plug and cold-start systems, head gaskets and head studs on built engines, and complete diesel rebuilds when the bottom end finally gives up. Fleet accounts are welcome — we set up scheduled service so your trucks come in before they break.

Signs Your Diesel Needs Service

  • Hard starting, especially in cold weather or after sitting
  • Loss of power under load or while towing
  • Excessive black, white, or blue smoke from the exhaust
  • Rough idle, misfire, or knock you can feel from the cab
  • Check engine light, DEF warning, or limp mode
  • Worse fuel economy than usual for no obvious reason
  • Coolant loss, overheating, or sweet smell from the engine bay
  • Fuel contamination (water in the bowl, gel from cold weather)

Powerstroke, Cummins & Duramax

Each platform has its own pattern of failures. Ford 6.0 and 6.7 Powerstroke injector and EGR work, Cummins lift-pump and CP3/CP4 work, Duramax injector balance and turbo work — we know which jobs need to be done together, which can wait, and which dealer repairs you genuinely don't need. We work on every diesel year and platform Idaho drivers run, from old IDI Fords to new Cummins H.O. and L5P Duramax.

Fuel Injector & Fuel System Service

Worn injectors are the leading cause of poor diesel performance — and the most over-quoted job in the dealer world. We test injector balance under load, replace only what's failing, and use OEM-grade or better parts. We also service high-pressure pumps, fuel filters, water separators, and fuel-pressure regulators. Contaminated fuel? We diagnose, drain, flush, and replace what got damaged.

Turbocharger, EGR & DEF Repair

Turbo housings, bearings, wastegate actuators, intercooler boots, EGR coolers and valves, DEF doser nozzles and pumps, NOx sensor diagnostics — the modern diesel emissions stack is complex, and most shops get it wrong. We diagnose the failure mode (often it's not the part the code points to), quote the actual fix in writing, and stand behind it with our 24-month / 24,000-mile warranty.

Glow Plugs, Cold Start & Electrical

Idaho winters are hard on diesels. Glow plug testing and replacement, glow plug controller diagnosis, intake-air heaters, block heater repair, dual-battery system service, and starter/alternator work for high-load diesel electrical demands. If your truck cranks but won't fire on a cold morning, we'll find the cause — not just throw a new battery at it.

Diesel Engine Rebuilds & Heavy Work

When the bottom end gives up — cracked head, spun bearing, failed lift pump that took out the injection pump — we do full rebuilds in-house. Head studs, ARP fasteners, fire rings, machined heads, balanced rotating assemblies. We document everything, use the right parts for the platform, and back the work with a real warranty. For a 200,000-mile work truck, a properly rebuilt engine is a fraction of the cost of a new diesel.

Common Questions

Frequently Asked.

How much does diesel repair cost?

Wide range, depending on the platform and the job. An injector job on a 6.0 Powerstroke runs $2,500–$4,500 depending on what else needs doing while we're in there. A turbo replacement is typically $2,000–$3,500. A full diesel rebuild starts around $8,000 and goes up based on heads, machine work, and built-engine specs. We diagnose first and quote in writing — no surprise charges.

Do you do CP4 to CP3 conversions on Powerstroke 6.7s?

Yes. We've done several. We'll quote the conversion kit, install, retune, and test — and we'll honestly tell you whether it's worth doing for your truck or whether other failures should be addressed first.

Can you handle DEF and emissions system problems?

Yes. We diagnose DEF doser nozzles, DEF pumps, DEF heater circuits, NOx sensors, DPF clogs, and emissions module failures. We follow EPA regulations — we don't delete emissions systems — but we'll quote a proper fix that gets your truck back to factory spec and out of limp mode.

How long will my diesel be in the shop?

Depends on the work. Fuel filter changes, glow plug replacement, simple sensor work — same day. Injectors, turbo, EGR — 2–5 days depending on parts. Full rebuilds — 2–4 weeks. We give a real timeline up front and text you progress photos throughout the job.

Do you work on heavy-duty / commercial diesel?

Yes — pickup-class diesels (6.0/6.7/7.3 Powerstroke, 5.9/6.7 Cummins, LB7 through L5P Duramax) are core to what we do. For Class 6+ heavy commercial trucks, talk to us — we may be able to do the work, or we can refer you to a specialized partner.

Will diesel repair void my truck's warranty?

No. Federal law (Magnuson–Moss) protects you from warranty voids just for using an independent shop. We use OEM-grade parts and document every repair. Your CARFAX shows the work.
